ABSTRACT
Current
estimates
indicate
that
up
to
160
short
tons
(
146
Mg)
of
mercury
(
Hg)
is
consumed
by
the
chlor­
alkali
industry
each
year.
Very
little
quantitative
information
is
currently
available,
however,

on
the
actual
Hg
losses
from
these
facilities.
The
Hg
cell
building
roof
vent
is
considered
to
be
the
most
significant
potential
emission
point
in
chlor­
alkali
plants,
especially
when
the
cells
are
opened
for
maintenance.
Because
of
their
potential
importance,
chlor­
alkali
plants
have
been
identified
as
needing
more
accurate
measurements
of
Hg
emissions.
To
obtain
a
better
understanding
of
the
fate
of
Hg
within
their
manufacturing
process,
the
Olin
Corporation
voluntarily
agreed
to
cooperate
with
the
U.
S.

Environmental
Protection
Agency
in
a
comprehensive
study
of
the
Hg
emissions
from
their
Augusta,

GA,
facility,
in
collaboration
with
other
members
of
the
Chlorine
Institute
representing
the
active
chloralkali
plants
in
the
United
States.

To
investigate
the
Hg
releases
from
the
Olin
chlor­
alkali
facility,
the
EPA's
National
Risk
Management
Research
Laboratory,
Air
Pollution
Prevention
and
Control
Division
(
EPA­
APPCD)
in
Research
Triangle
Park,
NC,
organized
a
special
study
involving
multiple
organizations
and
personnel.
However,
only
the
research
conducted
by
EPA­
APPCD
involving
roof
vent
monitoring
and
air
flow
studies
conducted
in
the
Olin
cell
building
is
discussed
in
this
report.

The
overall
objective
of
monitoring
the
cell
building
roof
vent
was
to
determine
the
total
elemental
mercury
(
Hg0)
mass
flux
from
the
cell
building
under
a
range
of
typical
wintertime
meteorological
conditions,
including
both
normal
operation
of
the
cell
building
and
routine
maintenance
of
Hg
cells
and
decomposers.
Secondary
objectives
of
the
research
were
to
perform
an
air
flow
mass
balance
for
the
building
and
to
compare
various
Hg
monitoring
methods
under
a
variety
of
sampling
conditions.
Both
objectives
were
met
during
the
February
2000
field
sampling
campaign,
which
showed
an
average
Hg0
emission
rate
of
0.36
g/
min
from
the
roof
ventilator
as
determined
over
the
9­

day
monitoring
period.

SECTION

INTRODUCTION
1.1
Background
Current
estimates
indicate
that
up
to
160
short
tons
(
146
Mg)
of
mercury
(
Hg)
is
consumed
by
the
chlor­
alkali
industry
each
year
(
Chlorine
Institute,
1999).
Very
little
quantitative
information
is
currently
available,
however,
on
the
actual
Hg
losses
from
these
facilities.
The
most
significant
potential
emission
point
in
chlor­
alkali
plants
(
CAPs)
is
thought
to
be
the
mercury
cell
building
roof
vent,
especially
when
the
cells
are
opened
for
maintenance.
Because
of
their
potential
importance,
CAPs
have
been
identified
as
needing
more
accurate
measurements
of
Hg
emissions.

In
order
to
better
understand
the
fate
of
mercury
within
their
manufacturing
process,
the
Olin
Corporation
voluntarily
agreed
to
cooperate
with
the
U.
S.
Environmental
Protection
Agency
(
EPA)
in
a
comprehensive
study
of
the
Hg
emissions
from
their
Augusta,
GA,
facility.
This
effort
is
in
collaboration
with
other
members
of
the
Chlorine
Institute
representing
the
active
chlor­
alkali
plants
in
the
United
States.

Chlorine
Institute
members
have
committed
to
reduce
overall
mercury
consumption
by
50%
(
from
1990­
95
levels)
by
the
year
2005.

To
investigate
the
Hg
releases
from
the
Olin
chlor­
alkali
facility,
the
U.
S.
Environmental
Protection
Agency's
National
Risk
Management
Research
Laboratory,
Air
Pollution
Prevention
and
Control
Division
(
EPA­
APPCD)
in
Research
Triangle
Park,
NC,
organized
a
special
study
involving
multiple
organizations
and
personnel.
Each
major
aspect
of
the
study
was
addressed
by
a
separate
Principal
Investigator
(
PI)
based
on
the
individual
area
of
expertise.
It
should
be
noted,
however,
that
only
the
research
conducted
by
EPA­
APPCD
involving
roof
vent
monitoring
and
air
flow
studies
conducted
in
the
Olin
cell
building
is
discussed
in
this
report.
The
following
sections

conducted
at
the
Augusta
plant,

objectives
of
the
specific
research
described

The
program
was
divided
into
two
phases:
a
preliminary
survey,
and
a
winter
sampling
campaign
conducted
in
February
2000.
A
summer
campaign
was
also
planned
to
evaluate
the
effects
of
elevated
ambient
temperature
but
this
phase
was
eliminated
and
thus
is
not
discussed
here.
Implementation
of
the
overall
program
is
briefly
outlined
below
with
formal
publication
of
the
results
by
the
respective
Principal
Investigator
planned
for
late­
2002.

1.2.1
Preliminary
Survey
The
purpose
of
the
survey
was
to
obtain
preliminary
information
to
assist
in
planning
the
second,

and
more
significant,
phase
of
the
program.
The
survey
included
measurements
of
the
typical
range
of
elemental
mercury
(
Hg0)
concentrations
in
the
cell
building
as
well
as
similar
measurements
external
to
the
cell
building.
In
addition,
flow
visualization
experiments
were
also
performed
and
meetings
held
with
Olin
operating
personnel
to
plan
the
logistics
of
the
winter
sampling
campaign.

The
Hg
monitoring
methods
used
in
the
preliminary
survey
generally
involved
portable
hand­
held
instruments,
including
both
the
Jerome
Model
431­
X
electrical
conductivity
analyzer
and
the
Lumex
Model
RA­
915
Zeeman
Mercury
Spectrometer.
The
Model
RA­
915
is
a
portable
cold­
vapor
atomic
absorption
(
CVAA)
spectrometer
capable
of
monitoring
Hg0
at
nanograms
per
cubic
meter
levels.
Both
instruments
were
used
to
measure
and
spatially
map
Hg0
levels
in
and
around
the
electrolytic
cells
as
well
as
upwind
and
downwind
of
the
cell
building.

In
addition
to
point
monitoring,
profiles
of
air
velocity
and
Hg0
concentration
were
also
obtained
near
the
entrance
to
the
roof
vent.
The
measurements
were
conducted
by
mounting
a
sampling
line
and
hotwire
anemometer
on
a
non­
conducting
mast
attached
to
the
upper
platform
of
the
movable
crane
used
for
cell
maintenance.
The
sampling
line
was
connected
to
a
Jerome
431­
X
electrical
conductivity
analyzer
with
the
velocity
measurements
made
at
selected
intervals
along
the
length
of
the
vent.

Finally,
since
the
determination
of
air
flow
is
critical
to
study
implementation,
special
flow
visualization
equipment
was
also
used
as
part
of
the
preliminary
survey.
This
equipment
included
an
infrared
camcorder
to
observe
and
record
thermal
plumes
from
the
cell
building
and
a
commercial
smoke
generator
and
associated
video
camcorder
for
visualizing
the
overall
flow
field
within
the
cell
room.
Flow
5
visualization
answered
several
important
questions
regarding
the
nature
of
the
air
flow
pattern
inside
the
building
as
well
as
dispersion
of
the
plume
after
it
exits
the
roof
vent.

1.2.2
Winter
Sampling
Campaign
The
overall
objective
of
the
winter
sampling
campaign
was
to
determine
the
total
Hg
release
from
the
plant
using
parallel
sampling
approaches
under
typical
wintertime
meteorological
conditions.
The
activities
in
the
winter
campaign
included:
roof
vent
monitoring,
point
source
measurements,
air
flow
studies,
flux
measurements,
upwind/
downwind
monitoring,
and
waste
and
product
evaluation.
The
locations
of
the
various
activities
at
the
Olin
plant
site
are
shown
in
Figure
1­
2.

As
stated
above,
the
research
described
in
this
report
includes
only
the
roof
vent
monitoring
and
air
flow
studies
conducted
by
EPA­
APPCD
with
contractor
support
from
OPSIS
®
,
Inc.
and
ERG.
The
other
related
activities
performed
by
study
collaborators
are
briefly
summarized
below.

Point
Source
Measurements
The
objective
of
the
point
measurements
was
to
characterize
the
distribution
of
airborne
Hg0
in
the
cell
room
(
including
the
floor
below
the
cells)
and
around
the
exterior
of
the
cell
building.
The
primary
instrument
used
for
point
monitoring
was
the
Tekran
Model
2537A
automated
Hg
analyzer.
The
Model
2537A
is
a
cold­
vapor
atomic
fluorescence
(
CVAF)
spectrometer
which
is
equipped
with
dual
gold
traps
for
preconcentration
of
the
sample
prior
to
analysis.
This
analyzer
was
housed
in
the
control
room
with
samples
obtained
from
a
high­
flow
sampling
line
which
extended
to
a
point
near
the
center
of
the
roof
vent
entrance.

In
addition
to
the
Tekran
monitoring,
walking
surveys
were
also
conducted
using
a
Jerome
Model
431­
X
and/
or
Lumex
Model
RA­
915
instrument.
These
data
were
combined
with
measurements
from
a
hand­
held
air
anemometer
to
identify
potential
hot
spots
and
any
ancillary
emission
points
found
in
or
around
the
cell
building.
Manual
"
denuders"
were
also
employed
to
determine
the
concentration
of
nonelemental
Hg
(
e.
g.,
divalent
Hg
compounds)
in
the
cell
room.
A
series
of
short­
duration
grab
samples
was
collected
from
the
crane
above
the
south
cell
line
and
analyzed
on­
site
using
a
Tekran
Model
2537A.
6
Preliminary
results
of
these
analyses
indicate
that
non­
elemental
forms
of
Hg
represent
<
~
5%
of
the
total
Hg
at
the
time
of
sample
collection
(

et
al.,
2000).

Flux
Measurements
Mercury
fluxes
from
surfaces
in
and
around
the
cell
building
(
especially
the
basement
floor
of
the
building)
were
also
determined
to
assess
the
role
of
these
surfaces
as
sources.
Flux
chambers
of
various
designs
were
used
over
the
cell
room
and
ground
(
basement)
floors
to
determine
their
source
strength
and
Hg0
emission
characteristics.
Chambers
were
also
deployed
over
old
waste
deposits
within
the
plant
facility
and,
since
solar
radiation
can
strongly
influence
soil
fluxes,
operated
throughout
the
diurnal
cycle.

Upwind/
Downwind
Monitoring
Upwind/
downwind
ambient
air
monitoring
was
also
conducted
as
part
of
the
overall
program.
The
purpose
of
this
monitoring
was
to
estimate
the
total
mass
flux
of
Hg
compounds
from
the
entire
facility
as
a
check
on
the
source
estimates
obtained
within
the
plant,
for
model
validation
purposes,
and
to
collect
data
which
can
potentially
be
compared
to
similar
measurements
conducted
outside
other
facilities.

For
the
upwind/
downwind
monitoring,
instrumentation
was
deployed
at
different
locations.
Tekran
analyzers
were
used
in
two
mobile
monitoring
laboratories
located
a
significant
distance
upwind
and
downwind
from
the
process
area
(
Figure
1­
2).
(
Note
that
two
of
the
Tekran
instruments
used
in
the
mobile
laboratories
were
a
Model
1130
analyzer
and
the
prototype
Model
1135
capable
of
measuring
gas­
and
particle­
phase
elemental
and
non­
elemental
Hg.)
In
addition,
an
open­
path
Fourier
Transform
Infrared
(
FTIR)
spectrometer
and
ultraviolet
differential
optical
absorption
spectrometer
(
UV­
DOAS)
were
also
installed
near
the
cell
building
in
the
prevailing
downwind
direction
(
Figure
1­
2).
Using
the
various
instruments,
the
concentration
of
elemental
and
non­
elemental
Hg
and
SF6
tracer
gas
could
be
determined
in
near­
real­
time.
(
Note
that
the
open­
path
monitoring
was
not
successful
due
to
atypical
wind
conditions
occurring
during
the
limited
9­
day
study
period.)

Waste
and
Product
Evaluation
Sampling
and
analysis
of
liquid
and
solid
wastes
and
selected
liquid
product
streams
were
also
performed.
Wipe
samples
were
also
collected
from
various
environmental
surfaces
including
building
walls
and
exterior
cell
surfaces.
These
samples
were
subsequently
analyzed
for
total
Hg,
Hg0
,
and
9
dissolved
reactive
Hg
(
also
referred
to
as
"
easily
reduced
Hg"),
as
appropriate,
using
a
Tekran
analyzer
as
the
primary
measurement
tool.

1.3
Research
Objectives
The
overall
objective
of
the
roof
vent
monitoring
described
in
this
report
was
to
determine
the
total
Hg0
mass
flux
from
the
cell
building
under
a
range
of
typical
wintertime
meteorological
conditions.
This
research
was
to
include
both
normal
operation
of
the
cell
building
as
well
as
routine
maintenance
of
Hg
cells
and
decomposers.
Secondary
objectives
of
the
research
were
to
perform
an
air
flow
mass
balance
for
the
building
and
to
compare
various
Hg
monitoring
methods
under
a
variety
of
sampling
conditions.
Each
of
these
objectives
was
met
in
the
study.

SECTION
2
CONCLUSIONS
AND
RECOMMENDATIONS
This
section
provides
conclusions
drawn
from
the
use
of
the
equipment,
methods,
and
data
analysis
procedures
described
in
Section
4
to
determine
the
total
Hg
release
and
volumetric
air
flow
from
the
Olin
chlor­
alkali
cell
building:

Elemental
mercury
concentrations
measured
by
the
UV­
DOAS
varied
over
an
order
of
magnitude
from
~
73
to
7.3
µ
g/
m3.
The
overall
average
for
the
9­
day
study
period
was
24
µ
g
Hg0/
m3.

Hg0
emission
rates
measured
in
the
roof
ventilator
varied
from
0.08
to
1.2
g/
min.
An
overall
average
for
the
monitoring
period
of
0.36
g/
min
(
472
g/
day)
was
calculated
from
the
data.
These
values
appear
to
represent
only
a
small
percentage
of
the
total
potential
Hg0
emissions,
however,
based
on
available
estimates
of
the
makeup
Hg0
added
to
the
cells
on
an
annual
basis.

A
comparison
between
the
concentration
of
Hg0
measured
by
the
UV­
DOAS
and
similar
measurements
conducted
using
a
hand­
held
instrument
across
the
width
of
the
roof
vent
showed
that
the
Hg0
concentrations
were
relatively
consistent
across
the
vent
and
compare
reasonably
well
to
the
average
concentration
obtained
with
the
UV­
DOAS.

Comparison
of
roof
vent
monitoring
data
obtained
by
the
UV­
DOAS
and
point
measurements
made
using
a
Tekran
Model
2537A
automated
Hg
analyzer
at
the
entrance
to
the
vent
exhibited
a
relatively
high
degree
of
scatter
with
only
about
63%
of
the
variance
explained
by
linear
regression.
The
data
do,
however,
show
comparable
trends
in
Hg0
concentration
with
time.
Scatter
in
the
data
is
potentially
due
to
a
combination
of
factors
including
differences
in
analysis
method,
non­
representative
sampling,
and
sampling
line
losses.

The
SF6
tracer
gas
results
obtained
using
the
long­
path
FTIR
in
the
roof
vent
were
found
to
be
unusable
for
the
purpose
of
determining
volumetric
air
flow
due
to
optical
saturation
of
the
detector.

Results
of
the
24­
hour,
time­
integrated
bag
sampling
showed
SF6
tracer
gas
concentrations
either
at
or
below
the
instrumental
detection
limit
except
for
one
sampling
period
on
February
20,
2000.
11

The
average
roof
vent
air
velocity
measured
by
a
hand­
held
anemometer
as
compared
to
that
obtained
by
the
optical
anemometer
showed
that
the
two
methods
agreed
within
±
10
%.

Very
good
closure
(
79
to
100%)
was
obtained
for
each
of
the
three
air
flow
balance
calculations
performed
for
the
cell
building.
The
three
methods
also
correlate
well
with
each
other,
and
the
high
degree
of
closure
of
these
flow
balances
lends
further
credibility
to
the
air
velocity
measurements
made
by
the
optical
anemometer
in
the
roof
ventilator.

No
specific
pattern
could
be
discerned
from
daily
plots
of
Hg0
emission
rates.
Various
episodic
events
were
observed
during
the
study
where
the
emission
rate
rose
for
a
period
of
time,
then
dropped
back
to
some
nominal
level
which
could
not
be
correlated
to
either
process
operation
or
maintenance
events
using
plant
records.

Although
the
concentration
of
Hg0
was
found
to
be
relatively
homogeneous
across
the
lateral
dimension
of
the
roof
vent,
concentrations
of
Hg0
were
not
consistent
along
the
length
of
the
ventilator.

On
the
basis
of
the
results
obtained
for
this
study,
the
following
recommendations
are
applicable:

This
study
was
conducted
at
one
chlor
alkali
plant,
in
a
time
window
of
approximately
2
weeks.
For
more
thorough
characterization
of
operations
in
this
industry,
extended
monitoring
at
a
single
location
and/
or
monitoring
at
more
plants
is
recommended
to
better
characterize
maintenance
events
and
other
operational
transients.
Better
monitoring
of
these
transients
is
also
needed.

Roof
vent
instrumentation
may
be
a
useful
tool
for
process
monitoring
in
some
facilities
to
identify
problems
in
the
operation
of
the
cells
that
may
require
corrective
action.
The
long­
term
suitability
of
these
instruments
must
be
established,
however,
by
additional
on­
site
evaluations.

The
high
electromagnetic
field
at
the
facility
had
an
adverse
effect
upon
instrument
operation.
For
future
studies
of
this
type,
optical
modems
and
cables
should
be
used
to
allow
logging
of
data
at
a
remote
location
to
reduce
data
loss
and
make
troubleshooting
much
easier
for
the
operator.

The
variation
in
Hg0
concentrations
along
the
length
of
the
ventilator
vs.
the
homogeneous
values
observed
for
Hg0
across
the
lateral
dimension
argue
strongly
for
the
use
of
spatially
integrated
measurements
rather
than
point
sampling
with
a
manifold
system.

Roof
vent
tracer
gas
data
in
this
study
were
not
usable.
Since
the
use
of
a
tracer
is
well
accepted
for
determining
flow
rates,
the
possibility
of
tracer
gas
analyses
for
future
flow
measurement
studies
should
not
be
abandoned.
Greater
care
is
needed,
however,
to
verify
proper
instrument
setup
and
operation.
12

The
possibility
of
using
different
tracer
gases
has
been
discussed.
Some
of
these
candidate
tracer
gases
(
e.
g.,
carbon
tetrafluoride)
can
be
determined
using
UV­
DOAS,
making
concurrent
sampling
and
analysis
of
mercury
and
tracer
gas
highly
desirable.
Additional
research
is
also
recommended
to
determine
the
best
way
to
diffuse
the
tracer
gas
into
the
cell
room.

Additional
measurements
of
non­
elemental
(
oxidized)
forms
of
Hg
should
also
be
conducted
to
determine
their
overall
environmental
significance.

SECTION

PROCESS
DESCRIPTION
AND
OPERATION
3.1
General
Process
Description
In
Hg
cell
CAPs,
Hg0
is
used
as
a
flowing
cathode
in
electrolytic
cells.
The
Hg
electrolytic
cell
consists
of
an
electrolyzer
and
a
decomposer.
In
the
electrolyzer
section,
a
sodium
chloride
(
NaCl)
brine
solution
flows
concurrently
with
the
Hg0
cathode.
A
high
current
density
is
applied
between
the
Hg0
cathode
and
metal
anodes.
Chlorine
gas
(
Cl2)
forms
at
the
anode
and
a
sodium
amalgam
forms
at
the
Hg0
cathode.
The
amalgam
is
separated
from
the
brine
in
a
discharge
end­
box
and
then
enters
the
decomposer
section,
where
deionized
water
is
added.
In
the
decomposer,
the
amalgam
becomes
the
anode
to
a
shortcircuited
graphite
cathode
resulting
in
formation
of
hydrogen
(
H2)
gas
and
sodium
hydroxide
(
NaOH),
and
conversion
of
the
amalgam
back
to
Hg0.
The
Hg0
is
then
recycled
to
the
inlet
end­
box,
where
it
reenters
the
electrolyzer.
Cell
surface
temperatures
of
~
66

C
(
150

F)
and
decomposer
surface
temperatures
of
~

116

C
(
240

F)
are
typical
at
the
Olin
facility.

The
chlor­
alkali
electrolysis
process
results
in
the
manufacture
of
Cl2,
H2,
and
NaOH
caustic
solution.
Of
these
three,
the
primary
product
is
Cl2.
The
overall
process
reaction
is:

2NaCl
+
2H2O

Cl2
+
H2
+
2NaOH

A
description
of
the
various
buildings
and
processes
at
the
facility
as
provided
by
Olin
can
be
found
in
Appendix
A.

The
Olin
facility
has
a
total
rated
output
of
309
Mg/
day
(
340
short
tons/
day)
of
Cl2,
348
Mg/
day
(
383
short
tons/
day)
of
NaOH,
and
8.2
Mg/
day
(
9
short
tons/
day)
of
H2
produced
by
the
60
cells
in
the
building.
According
to
plant
records
provided
to
the
research
team,
the
process
was
operated
at
a
relatively
constant
production
rate
except
for
a
few
brief
periods
when
cells
were
taken
off
line
for
maintenance.

3.3
Cell
Building
The
cell
building
at
the
Olin
facility
is
a
single
fiberglass
and
steel
structure
approximately
62
m
(
204
ft)
long
by
34
m
(
112
ft)
wide
which
is
generally
oriented
in
a
east/
west
direction.
The
peak
of
the
building
is
located
approximately
16
m
(
51
ft)
above
grade
with
a
single
monovent
(
Figures
3­
3a
and
3­
3b)

running
its
entire
length.

The
Hg
cell
building
consists
of
two
floors.
The
ground
floor
(
basement)
is
used
for
storage
tanks
and
various
other
process
equipment
and,
except
for
the
Reductone
®
area,
is
open
to
the
atmosphere
on
three
sides.
The
Hg
cells
and
associated
decomposers
are
mounted
on
a
support
structure
on
the
cell
room
floor
which
is
open
to
the
basement
below
except
for
concrete
aisles
along
the
edges
and
through
the
center
of
the
cell
array.
In
this
configuration,
each
cell
is
exposed
to
ventilation
air
used
for
cooling
or
worker
protection.

The
cell
building
houses
the
60
electrolysis
cells
(
Figures
3­
4
and
3­
5)
containing
a
total
estimated
Hg
inventory
of
~
169,000
kg
(
372,000
lb).
In
1997,
7,444
kg
(
16,411
lb)
of
"
virgin"
makeup
Hg
was
supplied
to
the
cells
(
Rosario,
2001).
This
amount
of
makeup
Hg
represents
~
5%
of
the
total
quantity
used
by
all
plants
in
the
chlor­
alkali
industry
during
that
year
(
Rosario,
2001).

The
electrolytic
cells
in
the
Olin
cell
building
are
mounted
in
two
rows
of
30
units
each
which
run
east
to
west
(
Figure
3­
6).
The
cell
rows
are
separated
by
a
~
2.4
m
(
8
ft)
wide
aisle
running
along
the
centerline
of
the
building
with
other,
~
3.4
m
(
11
ft)
wide
aisles
located
along
the
perimeter
of
the
cell
rows
to
allow
access
for
equipment
maintenance.
The
decomposers
used
for
Hg
recovery
(
Figure
3­
7)
are
located
on
the
end
of
each
cell
near
either
the
north
or
south
wall.

The
building
is
ventilated
by
natural
convection
with
three
sides
of
the
basement
and
cell
room
floor
(
except
for
the
Reductone
®
area)
open
to
the
atmosphere.
During
colder
weather,
two
large
sliding
doors
on
the
west
end
of
the
cell
room
floor
can
be
closed
to
reduce
ventilation.
Also,
various
1.1
m
(
3.7
ft)
high
panels
located
on
the
north
and
south
sides
of
the
building
can
be
either
removed
or
replaced
as
ambient
conditions
dictate.

To
further
assist
with
ventilation
of
the
cell

axial­
blade

located
in
and
along

can
also

operated,
as
needed,
depending
on
ambient
temperature.
Each
of
these
fans
is
rated
at
626
actual
m3/
min
(
22,100
actual
ft3/
min)
and
is
manually
activated/
deactivated
by
operating
personnel.

A
general
diagram
of
the
cell
building,
showing
the
cell
rows
and
general
fan
locations,
is
shown
in
Figure
3­
8.

In
general,
the
internal
temperature
of
the
cell
room
varies
with
the
ambient
outdoor
temperature.

The
impact
of
this
variation
on
ventilation
rate
is
discussed
in
further
detail
in
Section
4.2.3
below.

In
the
northwest
corner
of
the
cell
building
is
the
Reductone
®
process
area.
This
area
contains
reactors
used
for
the
production
of
303,000
L/
day
(
80,000
gal./
day)
of
liquid
sodium
hydrosulfite
which
is
operated
from
a
separate
control
room
in
that
part
of
the
building.
Since
sodium
amalgam
from
the
electrolytic
cells
is
used
in
this
process,
the
Reductone
®
area
is
also
a
source
of
fugitive
Hg
emissions.

Finally,
based
on
observations
made
during
the
study,
the
Olin
chlor­
alkali
plant
appeared
to
be
a
very
well
operated
and
maintained
facility.
General
housekeeping
of
the
cell
building
and
adjacent
areas
was
excellent
and
the
Olin
staff
were
found
to
be
highly
motivated
to
reduce
Hg
emissions
from
the
process.
Periodic
maintenance
was
also
performed
throughout
the
study
period
as
part
of
the
normal
operation
of
the
cell
building.
In
addition,
two
specific
maintenance
events
expected
to
generate
elevated
Hg
levels
were
monitored:
a
cell
opening
and
a
decomposer
"
basket"
changeout.
To
facilitate
maintenance,

both
operations
were
conducted
after
the
equipment
had
been
taken
off­
line
and
allowed
to
cool.
(
Note
that
cooling
of
hot
process
equipment
before
opening
is
not
only
a
good
maintenance
practice,
but
also
a
good
engineering
practice
to
minimize
release
of
Hg
emissions.)
Neither
of
these
events
resulted
in
abnormally
high
Hg0
concentrations
either
in
the
area
adjacent
to
the
maintenance
activity
or
in
the
roof
vent.

SECTION
4
EXPERIMENTAL
PROCEDURES
This
section
provides
detailed
information
on
the
field
measurements
conducted
during
the
period
February
17
to
25,
2000.
Both
the
manual
and
automated
techniques
are
described
along
with
the
procedures
used
to
reduce
and
analyze
the
experimental
data.

4.1
Measurement
Methods,
Setup,
and
Calibration
A
combination
of
measurement
methods
was
used
for
data
collection
at
the
Olin
chlor­
alkali
facility.
Past
studies
of
this
type
show
that
parallel
approaches
reduce
the
overall
uncertainty
of
the
estimates
and
provide
useful
constraints
on
measurement
accuracy.
The
methods
used
were:
roof
vent
monitoring,
tracer
gas
analyses,
and
manual
velocity
measurements.
Each
is
described
in
detail
below.

4.1.1
Roof
Vent
Monitoring
The
basic
measurement
approach
used
in
this
portion
of
the
research
was
the
"
roof
monitor
method"
developed
in
the
late
1970s
for
fugitive
emissions
(
Cowherd
and
Kinsey,
1986).
In
this
particular
study,
however,
long­
path
instruments
were
used
in
lieu
of
extractive
sampling
using
a
manifold
system
(
EPA,
1984).
The
use
of
long­
path
instruments
allows
measurements
to
be
made
on
a
spatially
integrated
basis,
thus
eliminating
problems
with
representative
sampling
typical
of
point
measurements.

The
primary
instrumentation
used
in
the
roof
vent
consisted
of:

UV­
DOAS
for
the
measurement
of
Hg0
concentration;

Optical
scintillometer
(
anemometer)
for
the
determination
of
air
velocity;
and

FTIR
spectrometer
for
the
measurement
of
SF6
tracer
gas
concentration.
26
This
equipment
was
selected
because
it
has
been
used
successfully
for
testing
of
similar
emissions
in
other
industries
monitoring
roof
vents.
In
fact,
the
Model
LOA­
104
optical
anemometer
has
recently
received
an
EPA
Reference
Method
14
equivalency
designation
for
the
determination
of
air
velocity
in
aluminum
pot
room
roof
vents
(
EPA,
1984;
Hunt,
1998).
The
long­
path
instruments
used
for
roof
vent
monitoring
are
described
in

The
long­
path
instruments
were
mounted
on
wooden
sampling
platforms
erected
at
the
east
and
west
ends
of
the
cell
building
roof
vent
(
Figure
4­
1).
The
UV­
DOAS
receiver,
FTIR,
and
optical
anemometer
transmitter
were
located
on
the
west
platform
with
the
UV­
DOAS
transmitter
(
light
source),
a
retroreflector,
and
the
optical
anemometer
receiver
mounted
on
the
east
platform.
Except
for
the
optical
anemometer,
the
signals
from
all
instruments
were
directed
by
optical
fiber
to
computerized
data
acquisition
systems
(
DASs)
located
in
a
trailer
parked
directly
beneath
the
roof
ventilator
at
the
west
end
of
the
cell
building.
For
the
optical
anemometer,
the
microprocessor
and
associated
laptop
computer
used
for
data
acquisition
were
located
on
the
sampling
platform
itself.
This
arrangement
was
necessary
due
to
the
high
electromagnetic
field
which
precluded
the
use
of
the
low­
voltage
modems
supplied
with
the
instrument.

Due
to
practical
considerations,
the
optical
measurement
path
of
all
the
instruments
was
positioned
slightly
above
the
exit
plane
of
the
ventilator
"
throat"
as
shown
in
Figure
4­
2.

29
Each
instrument
was
set
up
and
calibrated
according
to
the
operating
manual
and/
or
approved
Quality
Assurance
Project
Plan
(
QAPjP)
for
the
study
(
Kinsey
et
al.,
2000).
For
the
UV­
DOAS,
both
the
transmitter
and
receiver
units
were
bolted
to
steel
plates
attached
to
the
internal
building
structure
at
the
approximate
centerline
of
the
vent
cross
section.
Instrument
calibration
was
performed
at
the
beginning
and
end
of
the
study
using
a
sealed
Hg
gas
cell
placed
in
the
measurement
path.
Daily
checks
of
instrument
performance
were
made
by
OPSIS
®
personnel
who
operated
and
maintained
the
UV­
DOAS
during
the
course
of
the
study.

For
operation
of
the
optical
anemometer,
the
transmitter
and
receiver
were
bolted
directly
to
the
wooden
platform
on
the
south
side
of
the
roof
vent
centerline.
The
instrument
was
initially
compared
against
a
standard
unit
evaluated
in
the
National
Institute
for
Standards
and
Technology
(
NIST)
low­
speed
wind
tunnel
and
thus
is
considered
to
be
NIST­
traceable.
Since
a
dynamic
calibration
could
not
be
performed
on
site,
daily
quality
control
(
QC)
checks
were
made
each
morning
using
the
electronic
calibrator
supplied
with
the
instrument.
In
addition,
two
sets
of
manual
velocity
measurements
were
also
made
as
a
comparison
with
the
readings
made
by
the
optical
anemometer
as
described
below.

The
open­
path
FTIR
and
associated
retroreflector
were
also
bolted
to
the
wooden
platforms
on
the
north
side
of
the
roof
ventilator
centerline.
The
instrument
was
calibrated
both
before
and
after
the
main
data
collection
period
using
a
nitrogen
purge
followed
by
500
ppmv
n­
butane
and
25
ppmv
SF6
according
to
EPA
Method
TO­
16
(
EPA,
1999).
Daily
QC
checks
were
also
made
by
the
instrument
operator.
A
diagram
showing
the
location
and
beam
path
of
each
long­
path
instrument
relative
to
the
roof
vent
cross
section
is
shown
in
Figure
4­
3.

Finally,
a
Met
One
Model
062
temperature
controller
and
meteorological
station
and
associated
laptop
computer
were
also
installed
on
the
west
sampling
platform
to
monitor
air
temperature
and
relative
humidity.
This
system
provided
15­
min
average
data
for
these
two
parameters
as
logged
by
the
computer.

(
Note
that
the
high
electromagnetic
field
precluded
the
transfer
of
electronic
files
from
the
meteorological
station
computer
in­
situ
and
thus
the
data
were
provided
as
hard
copy
output
directly
from
the
computer.)

Note,
however,
that
the
meteorological
station
was
not
available
until
about
midday
on
February
21,
and
thus
temperature
and
humidity
data
are
not
available
for
the
entire
study.
The
available
data
were
analyzed,
however,
to
estimate
the
air
temperature
for
periods
where
actual
monitoring
was
not
conducted.

Ambient

for
the

were
also
obtained

With
regard
to

the
raw

stream
from
each

was
continuously
logged
and
accumulated
by

The

to
provide

4.1.2
Manual
Tracer
Gas
Analyses
The
SF6
tracer
gas
concentration
was
measured
inside
the
Hg
cell
building
by
ERG's
Optical
Measurements
Group
using
manually
operated
bag
samplers
and
a
closed­
cell
Nicolet
Magna
760
FTIR
to
analyze
the
gas
samples.
The
roof
vent
and
upwind/
downwind
monitoring
was
conducted
using
EPA­
operated
FTIRs
to
determine
tracer
gas
concentrations.
All
analyses
and
measurements
for
the
tracer
gas
were
completed
following
EPA
Method
TO­
16
(
EPA,
1999).
31
Manual
sampling
was
accomplished
by
drawing
sample
air
into
a
Tedlar
®
bag
over
a
nominal
24­
hour
period.
Tedlar
®
bags
were
used
for
air
sampling,
and
were
constructed
of
a
material
that
minimizes
adsorption
of
many
ambient
air
chemical
species.
Tedlar
®
bags
will
be
referred
to
as
"
bags"
for
the
remainder
of
this
section.
A
bag
sampling
location
consisted
of
a
rigid
container
with
an
enclosed
bag,

a
sample
pump
to
pull
a
vacuum
on
the
container,
and
associated
flow
measurement
and
control
devices
(
rotameters).

Sampling
was
achieved
by
placing
an
evacuated
bag
inside
the
container,
sealing
the
container,
and
attaching
a
pump
and
sampling
lines
to
the
container.
The
sample
pump
was
started
and
withdrew
air
from
the
container,
creating
a
vacuum
within
the
container
which
then
inflated
the
bag
by
drawing
in
sample
air.

Sampling
rate
was
controlled
by
adjustment
of
the
pump
flow
rate.

Multiple
sampling
locations
were
used
to
obtain
a
distribution
of
tracer
concentration
at
key
locations
in
and
around
the
cell
building.
The
locations
were
sampled
nearly
simultaneously
for
approximately
24
hours.
Sampling
locations
were
determined
based
on
estimated
air
flow
patterns
and/
or
wind
conditions
prior
to
sampling.

Prior
to
sampling,
all
equipment
was
inspected
for
proper
operation.
Bags
were
inspected
for
integrity,
and
the
sampling
containers
were
inspected
and
tested
for
leaks.
When
all
equipment
passed
inspection,
the
equipment
was
placed
in
its
designated
sampling
location
and
assembled.
All
clocks
used
during
sampling
were
synchronized
with
a
master
clock
set
to
the
atomic
clock
in
Boulder,
CO.

Due
to
the
density
difference
between
air
and
SF6,
all
flowmeters
were
calibrated
with
tracer
gas
before
sampling
using
a
manual
Buck
calibrator.
After
the
bag
samples
were
obtained,
they
were
removed
from
the
rigid
container
(
10­
gal.
drum),
labeled,
and
transported
to
the
trailer
for
analysis.
All
samples
were
analyzed
at
Olin
using
the
ERG
Nicolet
FTIR.

The
bag
samples
were
analyzed
by
FTIR
spectroscopy
because
of
the
high
sensitivity
of
FTIR
to
SF6
and
the
ability
of
FTIR
to
simultaneously
detect
many
other
analytes
of
interest.
The
FTIR
operating
parameters
are
given
in
Table
4­
2.
These
parameters
provide
acceptable
detection
limits
for
the
target
analytes
anticipated
in
this
study.

Prior
to
each
day's
analysis,
the
FTIR
instrument
was
checked
for
proper
operation,
and
a
background
spectrum
was
collected
using
ultra­
high
purity
nitrogen.
A
background
spectrum
was
considered
a
zero­
response
measurement.
After
the
background
spectrum
was
collected,
QC
measurements
were
performed
at
nominal
SF6
concentrations
of
0.1
and
0.5
ppm
(
volume).
QC
results
are
described
in
detail
in
Section
6.

4.1.3
Manual
Velocity
Measurements
Manual
anemometer
measurements
were
also
performed
as
part
of
the
study.
The
objective
of
these
measurements
was
to
evaluate
air
velocity
in
the
roof
vent
as
an
independent
check
on
the
optical
anemometer
as
well
as
to
determine
the
air
velocity
in
various
building
openings
for
the
purpose
of
performing
an
overall
flow
balance
for
the
cell
building.

The
original
study
design
proposed
the
use
of
three
specially
designed
"
anemometer
trees"

(
ATREEs)
for
the
determination
of
air
velocity
and
air
flow.
The
ATREEs
consisted
of
multiple
thermal
anemometer
probes
which
were
mounted
on
a
movable
metal
mast
and
connected
to
a
central
data
logger.

Upon
initial
deployment,
however,
it
was
determined
that
the
thermal
anemometers
used
in
the
ATREEs
were
far
too
sensitive
for
these
measurements
and
immediately
went
off­
scale.
Therefore,
a
hand­
held,

Davis
Instruments
TurboMeter
®
propeller
anemometer
was
used
for
the
manual
velocity
measurements.

This
instrument
is
capable
of
integrated
air
velocity
measurements
down
to
0.1
m/
s
and
thus
was
well
suited
to
this
particular
application.
The
propeller
anemometer
was
also
compared
with
a
hand­
held
33
hot­
wire
instrument
during
selected
measurement
periods.
Since
propeller
data
were
available
for
all
of
the
manual
measurements,
only
this
information
was
used
in
the
analyses
described
below.

Propeller
anemometer
readings
were
obtained
both
in
the
roof
ventilator
and
in
cell
building
openings.
For
the
vent
measurements,
readings
were
made
at
selected
locations
across
the
width
of
the
ventilator
throat
both
at
the
same
height
as
the
optical
anemometer
measurement
path
and
also
~
20
cm
(
8
in.)
below
the
throat
exit.
For
the
various
building
openings,
anemometer
readings
were
obtained
at
the
approximate
geometric
center
of
each
opening.
All
data
collected
during
the
manual
velocity
measurements
were
recorded
by
hand
in
a
bound
field
notebook.

4.2
Data
Reduction
and
Analysis
The
data
reduction
and
analyses
conducted
in
the
study
are
described
below.
Copies
of
the
Excel
®
spreadsheets
containing
the
reduced
data
are
appended,
as
appropriate.

4.2.1
Roof
Vent
Monitoring
For
the
Hg0
concentration
measurements
made
by
the
UV­
DOAS,
the
raw
30­
sec
average
values
generated
by
the
spectrometer
were
downloaded
directly
from
the
instrument
in
the
form
of
an
ASCII
text
file
for
each
day
of
the
study.
The
individual
text
files
were
then
imported
into
separate
pages
of
an
Excel
®
spreadsheet
where
the
data
were
checked
for
any
obvious
errors
or
anomalies.
Any
entries
in
the
spreadsheet
which
appeared
corrupted
or
questionable
were
deleted,
the
remaining
information
plotted
as
a
chronology,
and
summary
statistics
calculated
for
each
24­
hr
period.
In
addition,
a
second
data
set
consisting
of
1­
min
averages
was
downloaded
from
the
DAS
for
the
purpose
of
the
emission
rate
calculations.
These
data
were
analyzed
in
a
similar
fashion
except
that
graphs
and
summary
statistics
were
not
generated.

A
similar
procedure
was
also
used
for
analysis
of
the
optical
anemometer
results.
In
this
case,

however,
raw
1­
min
averages
were
generated
by
the
instrument
and
were
imported
as
ASCII
text
files
into
the
spreadsheet
pages.
Due
to
the
high
electromagnetic
field
and
subsequent
frequency
of
corrupted
data,

special
care
was
taken
to
check
each
data
line
prior
to
further
reduction
and
analysis.
Note,
however,
that
the
data
generated
by
the
optical
anemometer
were
provided
at
actual
roof
vent
temperature
and
pressure,
34
whereas
the
DOAS
results
were
reported
at
a
constant
temperature
of
30

C
(
86

F)
and
pressure
of
760.7
mm
Hg
(
29.95
in.
Hg).
Therefore,
an
appropriate
temperature
and
pressure
correction
was
applied
to
the
optical
anemometer
results
prior
to
the
two
data
sets
being
used
to
calculate
Hg0
emission
rates.

For
the
roof
vent
meteorological
station,
the
temperature
and
humidity
data
were
entered
by
hand
into
a
spreadsheet
from
the
hard
copy
records.
The
data
entries
were
then
checked
by
the
analyst
for
accuracy.
These
data
were
later
combined
with
applicable
ambient
temperature
information
to
make
the
necessary
corrections
for
the
emission
rate
calculations
described
below.

Finally,
probably
the
most
complex
data
set
to
be
analyzed
was
that
obtained
from
the
roof
vent
FTIR.
This
data
set
consisted
of
individual
infrared
(
IR)
spectra
generated
by
the
instrument
from
64
separate
scans
conducted
over
a
time
period
of
approximately
5
min.
The
individual
spectra
were
analyzed
by
post­
processing
to
determine
the
concentration
of
SF6
and
other
gases
of
interest.

Data
files
containing
the
FTIR
spectra
were
provided
to
two
separate
EPA
contractors
for
post­
test
data
reduction
and
analysis.
An
initial
set
of
~
300
spectra
collected
late
in
the
study
was
first
provided
to
Jeff
Childers
of
ManTech,
Inc.,
who
developed
the
basic
spectral
analysis
scheme
and
provided
a
quality
control
check
of
the
data
(
Appendix
B).
A
complete
set
of
spectra
(
including
those
provided
previously
to
ManTech)
was
also
furnished
to
EPA's
in­
house
contractor
(
ARCADIS
Geraghty
&
Miller)
who
conducted
a
separate
analysis
(
Appendix
C)
of
the
information
generated
in
the
field
using
the
methodology
developed
by
Childers.

As
stated
in
Childers'
report
(
Appendix
B),
the
FTIR
detector
was
found
to
be
optically
saturated
due
to
poor
instrument
setup
in
the
field.
Because
of
detector
saturation,
the
response
of
the
instrument
is
highly
non­
linear,
making
quantitative
interpretation
of
the
spectra
impossible.
Therefore,
the
entire
data
set
was
considered
to
be
unuseable
for
the
quantitative
determination
of
air
flow
rate
from
the
cell
building.

The
data
are
of
some
qualitative
interest,
however,
as
discussed
in
Section
5.

4.2.2
Tracer
Gas
Analyses
The
SF6
tracer
gas
was
released
as
a
diffuse
line
source
along
the
centerline
of
the
cell
room.
The
tracer
was
provided
from
two
separate
compressed
gas
cylinders
through
a
`
soaker
hose'
running
the
length
35
of
the
building.

cylinder
layout
along
the
cell
building
basement.
Figure

room.

Gas
was
metered
from
the
cylinder
using
a
pressure
regulator
and
precision
rotameter
which
was
calibrated
in
the
field
with
SF6
using
a
bubble
test
meter
prior
to
use.

The
total
average
gas
release
for
the
first
3
days
of
sampling,
February
17
through
February
20,

2000,
was
137.4
g/
min.
Gas
concentration
was
increased
on
February
21,
2000,
because
the
FTIR
instrument
was
detecting
baseline
amounts
of
SF6.
The
average
release
from
February
21
to
23,
2000,
was
248.1
g/
min.
Because
there
was
still
a
problem
with
the
detection
of
SF6
from
the
long­
path
roof
vent
FTIR,
the
rotameters
were
exchanged
and
calibrated,
and
a
higher
flow
was
set
to
run
the
last
2
days
of
sampling,
February
23
and
24,
2000.
The
average
release
was
3356.0
g/
min.
Gas
release
concentrations
are
listed
in
Table
4­
3.

4.2.3
Emission
Rate
Calculations
Using
the
data
sets
described
in
Section
4.2.1
above,
the
emission
rate
for
each
1­
min
averaging
period
was
calculated
according
to:

(

E
60VcAeC(

Where:

E
=
Hg
0
emission
rate
(
g/
min);
Vc
=
air
velocity
obtained
from
optical
anemometer
corrected
for
temperature
and
pressure
(

area
of
vent
(

and
C
=
Hg
0
concentration
as
measured
by
the
UV­
DOAS
(
µ
g/

The
corrected
air
velocity
was
calculated
by
Equation

To
obtain
the
value
of
Ta
in
Equation

2,
the
temperature
data
obtained
from
the
roof
vent
meteorological
station
were
used,
where
available.
However,
for
time
periods
when
actual
monitoring
was
not
conducted,
the
available
data
were
analyzed
separately
to
estimate
the
vent
air
temperature.

To
estimate
roof
vent
air
temperature,
the
available
monitoring
data
were
copied
into
a
separate
spreadsheet
and
the
difference
between
the
vent
temperature
and
the
ambient
temperature
calculated
for
each
15­
min
averaging
period.
The
temperature
differentials
( 
Ts)
obtained
from
these
calculations
were
then
plotted
on
the
same
graph
as
a
series
of
daily
time
histories.
Upon
examination
of
these
plots,
a
similar
daily
trend
in
 
T
was
observed,
as
would
be
expected
for
a
naturally
ventilated
building.

Appropriate
averages
were
then
calculated
from
the
15­
min
monitoring
results
which
were
subsequently
applied
to
the
ambient
temperature
data
for
those
time
periods
where
actual
monitoring
was
not
conducted.

The
time
histories
generated
from
the
monitoring
results
and
the
average
daily
 
T
cycle
calculated
from
these
data
are
shown
in
Figures
4­
6a
and
4­
6b,
respectively.
As
shown
by
Figure
4­
6b,
the
"
artificial"

chronology
developed
from
the
average
data
is
very
similar
to
the
daily
trends
actually
determined
from
the
monitoring
results
(
Figure
4­
6a)
and
thus
should
be
adequate
to
estimate
vent
air
temperature.

Finally,
the
concentration,
velocity,
temperature,
and
pressure
data
described
above
were
imported
into
an
Excel
®
spreadsheet
and
the
Hg0
emission
rate
calculated
for
each
1­
min
averaging
period
using
Equations
4­
1
and
4­
2.
Also
generated
in
the
spreadsheet
were
summary
statistics
and
a
time
history
for
each
24­
hr
period.

Manual
Velocity
Measurements
and
Flow
Balance
Calculations
For
the
manual
velocity
measurements
in
the
roof
vent,
the
data
from
the
field
notebook
were
entered
by
hand
into
an
Excel
®
spreadsheet
(
Appendix
D).
These
data
were
then
plotted
with
respect
to
the
physical
boundaries
of
the
ventilator
throat
and
averages
calculated
for
each
set
of
observations.
The
averages
were
then
compared
to
similar
values
obtained
from
the
optical
anemometer
for
the
same
time
period.
In
addition,
the
data
points
obtained
at
both
edges
of
the
ventilator
were
extrapolated
by
linear
regression
to
the
point
of
zero
velocity.
These
locations
were
then
used
to
determine
the
effective
flow
area
of
the
vent
(
Ae)
for
the
emission
rate
calculations
shown
in
Equation
4­
1
above.

In
the
case
of
the
building
openings,
the
manual
velocity
data
were
also
entered
by
hand
into
an
Excel
®
spreadsheet
(
Appendix
E).
These
values
were
then
multiplied
by
the
cross
sectional
area
of
each
opening
as
determined
either
from
building
drawings
or
field
notes
to
determine
volumetric
flow
rate.
The
individual
flow
rates
were
then
combined
with
the
total
volumetric
flow
of
the
electrically
powered
ventilation
fans
to
obtain
the
total
ambient
air
entering
the
cell
building.
Similar
calculations
were
also
performed
for
the
roof
vent
using
the
applicable
optical
anemometer
data
for
the
same
measurement
period
and
the
effective
flow
area
as
described
earlier.

To
perform
the
flow
balance
for
the
building,
three
separate
techniques
were
used.
The
first
technique
simply
corrected
the
total
flow
obtained
for
the
building
inlets
and
roof
vent
to
standard
temperature
and
pressure
and
compared
the
two
values
on
a
volumetric
basis.
In
the
second
method,
the
mass
of
air
entering
and
leaving
the
building
was
calculated
and
a
similar
comparison
made.
Finally,
a
method
developed
by
the
Occidental
Chemical
Corporation
(
OxyChem)
as
part
of
their
direct
mass
balance
(
DMB)
modeling
effort
was
also
used.
For
the
sake
of
consistency,
all
flow
balance
calculations
were
performed
in
English
units
as
described
in
the
following
paragraphs.

In
the
first
approach,
the
total
flow
for
both
the
building
inlets
and
the
roof
vent
was
corrected
to
a
standard
temperature
of
77

F
(
25

C)
and
pressure
of
29.92

(

according
to:

and
Ps
=

As
shown
by
Equation
4­
3
above,
no
correction
for
relative
humidity
(
water
vapor)
was
made
in
the
calculations.

Percent

of
the
volume
balance
was
then
calculated
as:

(
standard

and
Qout
=
volumetric
air

exiting
the
roof
ventilator
(
standard

In
the
second
calculation
scheme,
a
traditional
mass
balance
was
performed
which
compared
the
quantity
of
air
entering
the
building
through
the
various
openings
to
that
exiting
the
roof
vent
per
unit
time.

For
these
calculations,
the
partial
pressure
of
water
vapor
in
moist
air
(
pw)
at
the
building
inlet
and
outlet
was
found
by
(

and
ps
=

pressure
of
water

moist

(

Equation

assumes
that

is
approximately
equal
to
the
vapor
pressure
of
saturated
pure
water
(
pws)

which
is
generally
accepted
for
most
calculations
(
ASHRAE,
1981).

Next,
the

of
moist

of

(

was
found
for
the

from
Equation
4­

The
mass
of
air
either
entering

was
then
calculated
according
to
Equation

(

from
Equation

To
assess

RESULTS
AND
DISCUSSION
This
section
provides
the
results
of
the
Olin
field
study
as
obtained
using
the
equipment,
methods,

and
data
analysis
procedures
described
in
Section
4.
Also
included
in
this
section
is
a
discussion
of
key
experimental
results.

5.1
Mercury
Monitoring
Results
The
outcome
of
the
roof
vent
monitoring
conducted
at
the
Olin
cell
building
is
discussed
below.

Both
the
Hg0
emission
rates
calculated
from
the
continuous
monitoring
data
as
well
as
comparisons
of
the
UV­
DOAS
results
to
other
Hg0
measurement
techniques
are
also
described.

5.1.1
Monitoring
Data
and
Mercury
Emission
Rates
As
discussed
above,
continuous
monitoring
was
conducted
at
the
roof
vent
for
Hg0
concentration
and
air
velocity
from
which
1­
minute
average
Hg0
emission
rates
were
calculated.
In
addition,
continuous
monitoring
was
also
attempted
for
SF6
tracer
gas
as
a
separate
measure
of
the
air
flow
rate
from
the
vent.

The
results
of
these
measurements
are
discussed
below.

The
raw
30­
sec
averages
generated
by
the
UV­
DOAS
were
reduced
to
produce
daily
plots
of
the
Hg0
monitoring
results
as
well
as
summary
statistics
for
each
day.
The
daily
data
plots
are
shown
in
Figures
5­
1
to
5­
9
with
summary
statistics
calculated
from
the
data
provided
in
Table
5­
1.
As
can
be
seen
from
Table
5­
1,
the
measured
Hg0
concentration
varied
over
an
order
of
magnitude
from
~
73
to
7.3
µ
g/
m3.

The
overall
average
for
the
study
period
was
24
µ
g
Hg0/
m3.

Similar
plots
and
statistics
were
also
created
from
analysis
of
the
1­
min
optical
anemometer
data
as
discussed
in
Section
4.1.1.
The
plots
are
shown
in

was
also
calculated
from
the
data.

5.1.2
Comparison
of
Mercury
Measurement
Methods
In
addition
to
the
continuous
monitoring
described
above,
the
UV­
DOAS
results
were
also
compared
to
other
measurement
techniques
performed
by
collaborators
from
the
Oak
Ridge
National
Laboratory
(
ORNL).
Each
comparison
is
described
below
along
with
the
results
obtained.

In
the
first
analysis,
a
comparison
was
made
between
the
concentration
of
Hg0
measured
by
the
UV­
DOAS
and
similar
measurements
conducted
using
a
hand­
held
instrument
at
various
points
across
the
width
of
the
roof
vent
(
i.
e.,
from
north
to
south).
This
comparison
was
made
to
determine
whether
any
stratification
in
the
Hg0
concentration
was
evident
across
the
width
of
the
vent.
The
hand­
held
measurements
were
made
by
ORNL
using
a
Jerome
Model
431­
X
survey
instrument.
(
Note
that
the
Model
431­
X
uses
an
electrical
resistance
cell
to
measure
Hg0,
and
thus
the
readings
are
not
directly
comparable
to
an
optical
method
such
as
the
UV­
DOAS.
Also,
the
lower
detection
limit
of
the
Jerome
is
3000
ng/
m3
as
compared
to
~
130
ng/
m3
for
the
DOAS.)
The
data
obtained
from
this
evaluation
are
summarized
graphically
in
Figure
5­
28.

As
shown
by
Figure
5­
28,
the
Hg0
concentrations
determined
by
the
Jerome
instrument
were
relatively
consistent
across
the
width
of
the
vent
and
compare
reasonably
well
to
the
average
concentration
obtained
with
the
UV­
DOAS.
Based
on
these
results,
the
measurements
made
by
the
UV­
DOAS
were
considered
to
be
representative
of
the
entire
vent
cross
section
and

useful
for
the
purpose
of

Lateral

as

431­
X
instrument.

In
the
second
analysis,
monitoring
data
obtained
by
the
UV­
DOAS
were
compared
to
point
measurements
made
using
a
Tekran
Model
2537A
automated
Hg
analyzer
operated
by
ORNL.
The
Model
2537A
is
a
cold­
vapor
atomic
fluorescence
spectrometer
(
CVAFS)
originally
designed
for
ambient
air
monitoring
which
uses
gold
traps
to
preconcentrate
the
sample
prior
to
analysis.
The
Tekran
analyzer
was
located
in
the
cell
building
control
room
with
air
samples
collected
from
a
high­
flow
sampling
line
which
extended
to
a
point
in
the
ceiling
of
the
cell
building
~
5
m
(
16
ft)
below
the
approximate
center
of
the
roof
vent
entrance.

Selected
data
from
both
instruments
were
imported
into
an
Excel
®
spreadsheet.
The
two
data
sets
were
time­
synchronized
and
plotted
against
each
other,
and
a
simple
linear
regression
calculation
performed
on
the
data.
The
results
of
this
analysis
are
shown
in
Figure
5­
29.

As
Figure
5­
29
shows,
the
data
exhibit
a
relatively
high
degree
of
scatter
with
only
about
63%
of
the
variance
being
explained
by
the
linear
regression.
Possible
reasons
for
these
results
include
differences
in
analysis
method,
non­
representative
sampling
(
e.
g.,
sample
extraction
at
a
single
point
vs.
a
pathaveraged
method),
and
sampling
line
losses.
The
data
do,
however,
show
comparable
trends
in
Hg0
68
concentration
with
time
(
Figure
5­
30)
which
may
be
useful
for
identifying
process
upsets
or
maintenance
events
as
discussed
below.

5.2
Tracer
Gas
Results
The
results
of
the
tracer
gas
measurements
are
provided
in
the
following
paragraphs.
These
results
include
both
the
roof
vent
monitoring
conducted
using
the
open­
path
FTIR
and
the
manual
bag
sampling
conducted
in
various
building
openings.

5.2.1
Roof
Vent
Monitoring
As
was
discussed
in
Section
4.2.1
above,
the
FTIR
results
were
found
to
be
unuseable
for
the
purpose
of
determining
volumetric
air
flow
due
to
optical
saturation
of
the
detector.
However,
the
qualitative
results
are
of
at
least
some
general
interest.

In
the
analysis
of
the
IR
spectra,
several
trace
gases
other
than
SF6
were
found
in
measurable
amounts.
These
gases
include
carbon
monoxide
(
CO),
nitrous
oxide
(
N2O),
and
methane
(
CH4),
all
of
which
were
estimated
to
be
in
concentrations
above
background.
(
Note
that
background
readings
were
obtained
from
the
ambient
FTIR
located
at
the
east
plant
road
which
was
also
operated
by
EPA
as
part
of
the
larger
study.)
Although
the
emission
rate
of
these
compounds
could
not
be
quantified,
it
is
interesting
to
note
that
three
"
greenhouse"
gases
were
found
in
measurable
quantities
in
the
roof
vent
effluent.
The
exact
source(
s)
of
these
gases
could
not
be
determined,
however,
from
the
available
data.

5.2.2
Tracer
Gas
Study
 
Manual
Bag
Sampling
The
bags
were
sampled
manually
by
drawing
sample
air
into
a
Tedlar
®
bag
over
a
nominal
24­
hour
period.
Multiple
sampling
locations
were
chosen
(
Figure
5­
31)
to
obtain
a
distribution
of
tracer
concentrations
at
key
building
openings.
This
sampling
process
was
conducted
to
obtain
ambient
levels
of
SF6
released
along
the
open
areas
in
the
basement
and
in
the
cell
room.
If
SF6
were
detected,
it
would
have
indicated
possible
release
of
Hg
along
the
vents
from
the
cell
building.

The
sampling
results
for
the
manual
bag
analyses
are
presented
in
Table
5­
4.
The
average
concentration
of
SF6
for
the
low
release
days,
February
17
through
February
20,
2000,
was
0.019
ppmv,

which
is
just
over
the
detection
limit
of
0.008
ppmv.

Although
the

SF6
on

2000,
were
less
than

(

the

(

than
any

suggesting
very
minimal

The
bags
that
detected
SF6
were
located
on
the
upper
and

of
the

building.
Samples
were

5.3
Air
Flow
Study
Results
The
results
of
the
manual
velocity
measurements
and
the
associated
air
flow
balance
calculations
performed
for
the
cell
building
are
described
below.

5.3.1
Roof
Vent
Monitoring
The
data
obtained
from
the
manual
velocity
measurements
are
shown
in
Figures
5­
32
and
5­
33
for
the
east
and
west
sampling
platforms,
respectively.
As
these
graphs
show,
the
velocity
profiles
obtained
on
each
platform
exhibit
a
distinct
decrease
at
the
approximate
center
of
the
vent
created
by
a
structural
member
running
the
length
of
the
building.
In
addition,
the
air
velocity
drops
off
rapidly
outside
the
physical
boundaries
of
the
vent
throat
as
would
be
expected.

The
average
air
velocity
measured
manually
by
the
propeller
anemometer
was
also
compared
to
that
obtained
by
the
optical
anemometer
for
the
same
time
period.
The
results
of
this
comparison
are
provided
in
Table
5­
5.
As
shown,
the
average
air
velocities
determined
by
the
two
methods
were
within
+
10%
which
is
quite
acceptable
considering
the
differences
in
measurement
technique
(
i.
e.,
optical
vs.

mechanical),
the
limited
amount
of
manual
data
collected,
etc.
Based
on
these
results,
the
measurement
path
of
the
optical
anemometer
was
considered
to
be
located
at
a
point
representative
of
the
average
velocity
and
thus
appropriate
for
use
in
the
emission
rate
calculations.

5.3.2
Flow
Balance
Calculations
The
results
of
the
cell
building
flow
balance
calculations
are
shown
in
Table
5­
6
for
the
three
methods
described
in
Section
4.2.4.
As
Table
5­
6
shows,
unusually
good
closure
(
i.
e.,
79
to
100%)
was
obtained
in
each
of
the
three
flow
balance
calculations
performed.
In
addition,
the
three
methods
also
correlate
well
with
each
other,
providing
additional
confidence
in
the
calculations
performed.
Finally,
the
high
degree
of
closure
of
these
flow
balances
lends
further
credibility
to
the
air
velocity
measurements
made
by
the
optical
anemometer
in
the
roof
ventilator
to
adequately
characterize
the
air
flow
from
the
cell
building.

Discussion
of
Results
The
following
sections
discuss
the
results
presented
above
for
the
roof
vent
monitoring,
cell
building
air
flow
evaluation,
and
the
tracer
gas
study
conducted
at
the
Olin
chlor­
alkali
facility.

5.4.1
Roof
Vent
Monitoring
No
specific
pattern
could
be
discerned
from
the
daily
plots
of
Hg0
emission
rate
determined
from
the
roof
vent
monitoring
conducted
in
this
study.
Figures
5­
19
to
5­
27
demonstrate
that
various
episodic
events
were
observed
where
the
emission
rate
rises
for
a
period
of
time
then
drops
back
to
some
nominal
level.

An
attempt
was
made
to
correlate
these
episodes
to
either
process
operation
(
Figure
3­
3)
or
maintenance
events
using
plant
records.
Except
for
one
specific
event
on
February
20,
when
a
significant
Hg
leak
occurred
in
the
Reductone
®
area
of
the
building
,
this
analysis
failed
to
find
any
useful
association.

The
plant
operational
logs
were
simply
not
adequate
to
pinpoint
when
certain
maintenance
operations
were
performed
on
the
cells
and
thus
when
high
airborne
Hg
levels
might
be
expected.
The
data
do
suggest,

however,
that
roof
vent
instrumentation
may
be
a
useful
tool
for
long­
term
process
monitoring
to
identify
when
problems
occur
in
the
operation
of
the
cells
which
may
require
corrective
action.

Another
observation
made
during
the
study
involves
the
impact
of
the
high
electromagnetic
field
on
instrument
operation.
If
future
studies
of
this
type
are
conducted,
optical
modems
and
cables
should
be
used
for
the
optical
anemometer
to
allow
logging
of
the
data
at
a
remote
location.
This
procedure
would
substantially
reduce
the
amount
of
lost
data
and
make
troubleshooting
much
easier
for
the
operator.

Finally,
although
the
concentration
of
Hg0
was
found
to
be
relatively
homogeneous
across
the
lateral
dimension
of
the
roof
vent,
such
was
found
not
to
be
the
case
along
the
longitudinal
dimension.
This
observation
is
illustrated
in
Figure
5­
34
which
shows
Hg0
concentration
data
collected
during
the
January
presurvey
(
Appendix
G).
These
data
were
obtained
by
sampling
from
the
mobile
crane
over
the
south
cell
line
using
a
Jerome
Model
431­
X
survey
instrument
and
a
long
sampling
tube
attached
to
a
non­
conducting
pole
which
extended
to
a
point
near
the
entrance
of
the
roof
ventilator
throat.

As
shown
in
Figure

the
Hg0
concentrations
were
not
consistent
along
the
length
of
the
ventilator.
The
lowest
concentrations
were
found
on
the
west
end
of
the
building
near
the
two
large
open
doors.
Figure
5­
34
also
at
least
partially
explains
the
lack
of
correlation
between
the
Tekran
and
DOAS
measurements
described
earlier.
These
differences
constitute
yet
another
argument
supporting
spatially
integrated
readings
in
lieu
of
point
sampling
with
a
manifold
system.
However,
also
note
that
these
measurements
were
conducted
below
the
ventilator
throat,
which
can
also
affect
the
homogenity
of
the
Hg0
levels
obtained.

5.4.2
Building
Air
Flow
Evaluation
Unexpectedly
good
closure
was
obtained
for
each
of
the
three
air
flow
balance
calculations
performed
in
the
study,
especially
for
February
25
(
Table
5­
6).
One
possible
reason
the
balance
obtained
for
February
25
has
the
highest
degree
of
closure
is
that
the
manual
velocity
data
were
collected
very
quickly
(
i.
e.,
within
about
15
min)
as
compared
to
the
previous
day
when
the
measurements
required
about
78
1.5
hr
to
complete.
Conditions
within
the
cell
building
tend
to
change
rapidly;
thus,
there
is
a
need
to
obtain
the
necessary
data
over
as
short
a
time
period
as
possible.
A
much
larger
data
base
is
required,

however,
to
verify
the
results
of
the
current
flow
study
at
other
naturally
ventilated
buildings
of
this
type.

As
a
final
note,
it
was
unfortunate
that
the
roof
vent
tracer
gas
data
were
not
useable
in
our
analysis.
The
use
of
a
tracer
is
a
very
well
accepted
technique
for
determining
flow
rates
in
situations
where
other
methods
prove
difficult
to
implement.
Therefore,
the
possibility
of
a
tracer
gas
analysis
for
future
flow
measurement
studies
should
not
be
abandoned.
However,
greater
care
is
needed
to
verify
proper
instrument
setup
and
operation
in
the
field.

5.4.3
Comparison
with
Historical
Information
Additional
analyses
can
be
made
of
the
data
obtained
in
the
study
which
are
worthy
of
note.
First
is
the
comparison
of
the
current
results
with
those
of
prior
emission
testing
of
chlor­
alkali
plants.
For
this
analysis,
only
four
documents
were
found
in
the
literature
which
provide
emission
data
for
cell
building
roof
vents.
Two
of
these
documents
were
EPA
reports
of
contractor
testing
conducted
in
the
1970s
as
part
of
the
original
development
of
the
Hg
National
Emission
Standard
for
Hazardous
Air
Pollutants
(
R.
F.

Weston,
1971;
Marks
and
Davidson,
1972).
The
other
two
documents
were
journal
articles
of
two
remote
sensing
studies
conducted
in
Sweden
and
Italy
(
Edner
et
al.,
1989;
Ferrara
et
al.,
1992,
respectively).
The
remote
sensing
studies
were
conducted
using
light
detection
and
ranging
(
LIDAR)
systems
to
profile
the
plume
from
the
cell
building
and
as
such
were
indirect
measures
of
the
Hg0
emissions
from
the
building.

Table
5­
7
summarizes
the
data
contained
in
the
above
documents
as
compared
to
current
study
results.
As
shown,
the
daily
emission
rate
obtained
at
the
Olin
facility
is
a
factor
of
~
2
to
3
lower
than
that
obtained
in
prior
testing
reported
in
the
literature.
It
should
be
noted,
however,
that
the
literature
values
are
based
on
generally
outdated
information
from
studies
of
more
limited
duration
as
compared
to
the
current
research.

Another
observation
that
can
be
made
from
the
historical
data
is
a
comparison
of
the
estimated
annual
emissions
from
the
cell
building
roof
vent
to
the
amount
of
makeup
Hg
added
by
the
plant.

actually
be
the
case,
172
kg/
year
of
Hg0
would
theoretically
be
released
to
the
atmosphere
from
the
cell
building
vent.
This
value
represents
2.3%
of
the
total
makeup
Hg0
added
by
the
plant
in
1997.
Note,

however,
that
Olin
has
implemented
an
aggressive
Hg
conservation
program
since
1997,
and
it
is
currently
not
known
how
much
Hg
was
actually
added
during
the
year
in
which
the
study
was
conducted
(
2000).

Therefore,
the
above
comparison
is
probably
not
valid
for
the
2000
operating
year.
However,
taking
these
factors
into
consideration,
it
still
appears
that
a
substantial
percentage
of
the
potential
Hg
emissions
were
not
measured
in
the
roof
vent
during
the
current
study.
Data
from
other
parts
of
the
measurement
program
described
in
Section
1.2
may,
however,
provide
additional
information
on
other
Hg
sources
within
the
plant
which
are
not
currently
available
for
analysis.
80
Finally,
in
the
1997
Mercury
Study
Report
to
Congress,
18.8
Mg/
yr
was
estimated
for
all
noncombustion
Hg
sources
for
the
period
1994­
95
(
Keating
et
al.,
1997).
Again
assuming
that
the
above
annual
emissions
from
the
current
study
are
valid,
the
Olin
cell
building
represents
less
than
1%
of
the
total
non­
combustion
Hg
emissions
inventory
for
1994­
95.
Also,
assuming
a
worst
case
makeup
Hg
consumption
for
the
entire
industry
of
146
Mg
as
mentioned
in
Section
1,
the
Olin
cell
building
annual
emissions
would
constitute
approximately
0.1%
of
this
value.

Based
on
the
above
analyses,
there
is
an
apparent
discrepancy
between
the
results
obtained
in
the
current
study
and
the
potential
Hg
emissions
from
this
and
other
CAPs.
However,
a
number
of
factors
could
explain
differences
in
the
Hg0
emission
rate,
including
better
process
control
and
increased
plant
maintenance.
It
is
recommended,
therefore,
that
extended
monitoring
at
the
Olin
plant
and/
or
monitoring
at
additional
plants
be
performed
to
address,
among
other
issues,
maintenance
events
and
operational
transients
which
are
suspected
as
being
the
major
cause
of
Hg
release
to
the
atmosphere
from
the
cell
building.

QUALITY
ASSURANCE/
QUALITY
CONTROL
A
number
of
quality
control
(
QC)
checks
were
made
for
the
measurements
conducted
in
the
study.

For
the
automated
methods,
both
long­
path
and
point
monitors,
checks
included
calibration
using
standards,
daily
system
checks,
and
calibration
of
flow
meters.
For
the
manual
techniques,
QC
checks
included
duplicate
samples,
field
and
instrument
blanks,
QC
samples,
and
spiked
samples.
Table
6­
1
summarizes
the
QC
checks
used
for
the
various
measurements
conducted
in
the
program.
More
detailed
information
on
these
checks
can
be
found
in
the
following
sections.
As
discussed
in
Section
1,
only
the
cell
room
data
are
discussed
in
this
report.
The
other
collaborators
in
this
study
will
provide
the
quality
assurance
from
their
programs
in
separate
publications.

6.1
UV­
DOAS
Measurements
The
UV­
DOAS
instrument
used
in
the
roof
vent
was
initially
calibrated
in
the
laboratory
using
an
optical
bench.
In
the
field,
instruments
were
calibrated
using
a
sealed
optical
cell
with
the
concentration
determined
based
on
temperature.
Temperature
was
measured
by
a
calibrated,
laboratory­
grade
electronic
thermometer.
Calibrations
are
presented
in
Appendix
H
for
the
Hg0
response
obtained
on
February
17,
24,

and
25,
2000.
QC
checks
are
reported
in
Table
6­

and
percent
completeness
was
shown
previously
in
Table

6.2
Optical
Anemometry
As
mentioned
in
the
Quality
Assurance
Project
Plan
(
Kinsey,
et
al.,
2000),
an
assessment
of
precision
and
accuracy
for
the
optical
anemometer
was
not
possible.
However,
percent
completeness
was
calculated
for
each
24­
hr
monitoring
period
as
shown
previously
in
Table
5­
2.
In
addition,
QC
checks
were
also
performed
each
morning
using
the
electronic
calibrator
supplied
with
the
instrument.

Release,
Sampling,
and
Analysis
(
FTIR)

The
SF6
tracer
gas
was
released
as
a
diffuse
line
source
along
the
centerline
of
the
cell
room.
The
tracer
was
provided
from
compressed
gas
cylinders
through
a
"
soaker
hose"
running
the
length
of
the
building.
Gas
was
metered
from
the
cylinder
using
a
pressure
regulator
and
precision
rotameter
calibrated
with
SF6
using
a
bubble
test
meter
prior
to
deployment.
Single­
point
calibration
checks
were
made
at
least
every
4
days
throughout
the
program.
Calibrations
are
presented
in
Appendix
I
for
the
rotameter
calibrations
obtained
on
February
16
and
23,
2000.
84
QC
procedures
for
bag
sampling
and
analysis
were
performed.
Sampling
QC
activities
were
conducted
separately
from
analytical
QC.
Field
sampling
data
were
recorded
in
a
laboratory
notebook.

Copies
of
the
notebook
pages
are
presented
in
Appendix
J.

Sampling
QC
included
daily
inspection
of
the
FTIR
spectrometer
and
a
bag
container
leak
check.

Sampling
system
QC
was
performed
prior
to
each
sample
run
including
blank
values
for
each
sample
collection
bag.
Acceptable
blank
values
were

5x
MDL
(
MDL
for
closed
cell
SF6
=
0.008
ppbV).
Blank
and
quality
control
checks
are
reported
in
Tables
6­
4
and
6­
5,
respectively.

QC
procedures
for
the
FTIR
spectrometer
included:


Instrument
sample
cell
integrity
check;


Collection
of
diagnostic
spectra;
and

Gas
standard
measurements.

These
procedures
were
conducted
each
test
day
prior
to
analysis.
Diagnostic
spectra
were
collected
for
the
SF6
gas
standards
which
included
0.1
and
0.5
ppm
SF6.
The
analytical
procedures
for
both
diagnostic
spectra
and
gas
standards
were
identical.
All
calibration
procedures
for
bag
sample
collection
and
FTIR
analysis
were
included
in
the
Standard
Operating
Procedure
(
SOP)
as
listed
in
Table

above.

6.4
Long­
Path
FTIR
QA/
QC
Checks
(
Roof
Vent)

Based
on
the
quality
review
provided
by
ManTech
Environmental,
the
data
from
the
long­
path
roof
vent
FTIR
were
not
used.
Appendix
B
contains
a
complete
description
of
problems
with
data
validation.

For
calibration
and
QA/
QC
purposes,
the
roof
vent
FTIR
optical
cell
was
first
purged
with
99%

purity
nitrogen.
During
this
procedure
a
background
spectrum
was
collected
and
recorded.
After
purging,

the
instrument's
optical
cell
was
challenged
with
n­
butane
certified
at
500
ppm.
Resulting
spectra
were
collected
and
recorded.
Then
the
cell
was
again
purged
with
99%
purity
nitrogen
to
remove
any
residue.

The
cell
was
then
challenged
with
SF6
certified
at
25
ppm.
Resulting
spectra
were
collected
and
recorded.

Finally,
the
cell
was
again
purged
with
99%
purity
nitrogen.
This
procedure
was
performed
before
the
85
FTIR
began
to
collect
data
and
when
data
collection
for
the
study
was
completed.
For
QA/
QC
purposes,

the
FTIR
was
purged
with
99%
purity
nitrogen
and
challenged
with
SF6
throughout
the
sampling
period.

With
the
exception
of
the
FTIR

monitoring,
only
one
other
DQI
failed
to
meet
acceptance
criteria.
Because
of
the
optical
saturation
of
the
FTIR

used
for
the
Roof

the
DQIs
were
not
achieved;
the

OCEAN
BUILDING
This
building
contains
the
equipment
we
use
to
respond
to
product
emergencies
that
occur
outside
the
plant.
The
acronym
OCEAN
stands
for
Olin
Chemical
Emergency
Action
Network.
We
have
a
trained
team
that
will
respond
to
a
product

you
will
be
able
to
see
the
OCEAN
trailer,
which
is
set
up
in

ANODE
SHOP
This
shop
contains
the
equipment
used
to
rebuild
worn
or
damaged
anodes
that
have
been
removed
from
the
cells.
The
rebuilt
anodes
are
then
placed
in
stock
and
are
reinstalled
in
another
cell
at
a
later
date.

The
anode
is
constructed
of
titanium
metal
that
is
coated
with
a
thin
precious
metal
coating.
The
coating
will
wear
off
in
time
and
will
eventually
have
to
be
replaced.

SODIUM
HYDROSULFITE
AREA
(
Reductone
®
and
Hydrolin
®
)


Sodium
Hydrosulfite
loading
and
storage
Sodium
Hydrosulfite
is
stored
in
six
insulated
fiberglass
tanks.
It
must
be
kept
cool
since
it
will
decompose
when
it
gets
too
warm.
It
is
stored
at
a
slightly
stronger
concentration
than
required
by
our
customers
and
is
diluted
to
proper
specifications
as
it
is
loaded
into
insulated
trailers
through
the
piping
on
the
loading
stations.
135,000
gallons
of
material
can
be
stored
in
these
tanks.


Sodium
Hydrosulfite
Refrigeration
The
Sodium
Hydrosulfite
reaction
is
exothermic
­­
it
gives
off
heat.
This
heat
must
be
removed
from
the
process.
The
major
portion
of
the
heat
removal
is
accomplished
using
the
two
large
Carrier
Corporation
refrigeration
units
housed
in
this
building.
A­
2

Sodium
Hydrosulfite
Reactors
The
Sodium
Hydrosulfite
reactors
are
sophisticated
mixers.
They
take
in
water,
sulfur
dioxide,
caustic
and
sodium
amalgam
to
produce
a
solution
of
sodium
hydrosulfite.
The
operating
parameters
­­
acidity
concentrations
and
mixing
rates
­­
must
be
carefully
controlled
to
get
the
proper
product
quality.
Computers
help
control
this
operation
using
software
designed
by
Olin
Technical
Center
Engineers.

4
FIRE
HOSE
STATION
The
small
red
building
located
on
the
side
of
the
roadway
contains
fire
hoses
and
other
fire
fighting
equipment.
These
stations
are
located
throughout
the
plant.

5
SAFETY
SHOWER
Also,
located
throughout
the
plant
are
many
safety
showers
and
eye
wash
stations.
In
the
event
an
employee
is
exposed
to
acid,
caustic,
or
other
chemicals,
a
safety
shower
is
always
close
by
so
the
employee
can
quickly
turn
on
the
shower
and
flush
away
the
dangerous
material.

6
MAIN
CONTROL
ROOM
This
control
room
has
equipment
used
to
monitor
all
major
plant
processes.
The
front
panel
houses
the
equipment
which
measures
and
controls
the
amount
of
DC
electrical
power
applied
to
the
cells.
The
back
panel
contains
instrumentation
to
monitor
and
control
most
of
the
major
processes
in
the
plant,
such
as
tank
levels,
pH
measurements,
line
pressures,
etc.

7
AUTOMATIC
ANODE
ADJUSTING
SYSTEM
This
computer
controlled
system
continuously
scans
all
sixty
cells
and
automatically
adjusts
the
anodes
in
each
cell
to
optimize
the
operation
of
each.
By
doing
so,
the
amount
of
electrical
power
needed
to
produce
a
given
amount
of
product
is
greatly
reduced
and
the
life
of
the
anodes
is
greatly
extended
since
the
computer
can
make
this
adjustment
far
more
accurately
than
humans
can.

8
CELL
ROOM
The
cell
room
is
the
heart
of
our
process.
Here
up
to
160,000
amps
of
DC
electricity
pass
through
the
60
electrolytic
cells.
In
the
cell,
brine
(
salt
water)
is
electrolytically
reduced
to
sodium
and
chlorine.
The
wet
chlorine
gas
from
the
cells
flows
through
a
drying
system
to
remove
all
the
water
from
it
and
then
travels
on
to
the
compressor
building.
The
sodium
combines
with
mercury
and
flows
to
the
decomposer.
In
the
decomposer,
the
sodium
reacts
with
water
and
forms
sodium
hydroxide
(
caustic).
Caustic
is
pumped
through
cooling
and
filtration
equipment
and
then
is
transferred
to
product
storage.
A
by­
product
from
the
decomposer
is
hydrogen
gas.
It
passes
through
coolers
and
then
on
to
blowers.
It
is
burned
in
our
boilers
for
steam
generation.
It
is
also
used
for
production
of
hydrochloric
acid
and
it
is
sold
to
Sunox
Corporation.

BRINE
DECHLORINATION
In
this
area,
the
residual
chlorine
left
in
the
spent
brine
leaving
the
cells
is
removed.
This
is
accomplished
by
passing
the
brine
through
two
tanks
that
are
kept
under
a
high
vacuum.
The
vacuum
"
boils"
the
chlorine
gas
out
of
the
brine
stream.
The
chlorine
is
recovered
and
the
dechlorinated
brine
is
pumped
to
the
CP
Salt
Tank
where
it
picks
up
a
renewed
supply
of
salt
prior
to
beginning
its
return
trip
to
the
cells.

10
HYDROGEN
BLOWERS
Hydrogen
is
taken
from
the
decomposers
and
passes
through
coolers
that
are
cooled
with
chilled
water.
The
cooling
process
removed
most
of
the
heat
and
mercury.
The
mercury
is
returned
to
the
process.
Hydrogen
is
then
compressed
using
one
or
both
blowers
and
sent
to
the
boiler
house
where
it
is
used
as
fuel
and
is
also
sent
to
other
users.

11
AC
POWER
DISTRIBUTION
Georgia
Power
provides
our
electrical
power.
Incoming
voltage
is
115,000
volts.
Here
we
step
it
down
to
13,800
volts,
rectify
part
of
it
for
the
cell
room
use
and
distribute
the
remaining
for
usage
throughout
the
plant
at
various
voltages
(
2400,
480,
120).

12
BRINE
FILTERS
This
is
the
first
stage
of
brine
purification.
Fourteen
brine
filters
are
used
to
filter
impurities
from
the
brine.
Each
filter
is
independent
of
all
others
and
must
be
removed
from
service
periodically
and
backwashed
for
cleaning.
The
dirty
backwashed
brine
is
then
collected
in
a
tank,
cleaned
and
recycled
in
the
filter
backwash
system.

13
BRINE
SETTLER
The
480,000
gallon
brine
settler
tank
is
used
to
settle
out
insoluble
sludge
in
the
brine.
The
sludge
is
flushed
out
the
bottom
of
the
settler.

14
PURASIV
®
UNITS
Hydrogen
is
a
by­
product
of
the
chlor/
alkali
process
and
it
is
contaminated
with
small
quantities
of
mercury.
The
mercury
concentration
must
be
further
reduced
before
the
hydrogen
can
be
used.
This
is
accomplished
by
passing
the
hydrogen
through
packed
carbon
beds,
which
absorb
mercury.
Absorbers
polish
and
further
remove
mercury
before
the
hydrogen
is
sent
to
our
HCl
plants.

BOILER
HOUSE
The
steam
generation
plant
consists
of
two
separate
boilers
­­
each
capable
of
producing
15,000
pounds
of
steam
per
hour
at
250
pounds
per
square
inch
of
pressure.
They
are
normally
fired
with
hydrogen.
They
can
operate
on
natural
gas,
if
necessary.

The
steam
is
used
throughout
the
plant
for
various
purposes,
such
as
brine
dechlorination,
brine
heating,
steam
tracing
of
lines
and
heating
certain
tanks.

SECONDARY
TREATMENT
All
liquid
waste
streams
contaminated
with
mercury
must
be
cleaned
before
allowing
them
to
proceed
into
our
waste
treatment
system.
On
the
average,
the
concentration
of
mercury
in
these
wastes
is
reduced
to
less
than
50
parts
per
billion
of
the
discharged
solution.

DECOMPOSER
REPAIR
BUILDING
The
Decomposer
Repair
Building
holds
equipment
to
rebuild
and
repack
cell
room
decomposers.
The
decomposer
is
filled
with
graphite
pellets
which
aid
in
creating
the
sodium
hydroxide
solution.

SUNOX
CORPORATION
The
Sunox
Corporation
is
one
of
Olin's
customers.
They
purchase
hydrogen
gas
from
Olin.
It
is
delivered
to
them
through
the
pipeline
along
the
side
of
the
roadway.
They
receive
and
compress
the
hydrogen
gas
and
load
it
into
the
trailers
parked
at
the
loading
stations.
The
hydrogen
is
then
shipped
to
customers
in
Augusta
and
throughout
the
Southeast.

INSTRUMENT
AND
ELECTRICAL
SHOP
This
shop
is
equipped
with
test
equipment
and
tools
required
to
repair
and
troubleshoot
the
electrical
equipment
and
the
large
number
of
instruments
needed
to
keep
the
Augusta
Plant
operating
efficiently.

20
COOLING
TOWERS
These
large
cooling
towers
are
one
of
the
ways
Olin
reduces
water
consumption.
The
plant
uses
about
6000
gallons
per
minute
of
water
to
remove
heat
from
the
process
by
pumping
the
water
through
various
heat
exchangers.
The
hot
water
is
then
recycled
back
to
the
cooling
towers
where
evaporation
cools
the
water
so
it
can
be
used
again.

21
PLANT
EFFLUENT
SYSTEM
Waste
water
streams
are
collected
throughout
the
plant
in
the
process
sewer
system.
This
is
the
covered
concrete
ditch
running
through
the
center
of
the
plant.
Also,
all
rainwater
runoff
is
collected.
All
of
this
water
is
monitored
for
pH,
mercury,
and
chlorine
content
before
it
is
released.
If
the
streams
are
not
acceptable,
they
are
treated
in
the
large
tanks
you
see
beside
the
road
before
the
water
is
discharged
to
the
Savannah
River
through
a
monitored
and
regulated
national
pollutant
discharge
elimination
system.

22
GROUND
WATER
FILTERS
The
square
filters
beside
the
roadway
are
used
to
treat
the
groundwater
from
shallow
wells
around
the
plant.
Here
rainwater
that
has
collected
underground
is
pumped
to
the
surface,
checked
for
pH
and
mercury
content,
treated
if
necessary
and
released.

CP
SALT
STORAGE
TANK
The
CP
salt
is
received
in
100
ton
hopper
cars
from
Olin's
diaphragm
cell
plant
in
McIntosh,
Alabama.
It
is
pumped
from
the
hopper
cars
into
the
CP
sale
storage
tank,
from
which
is
it
pumped
to
the
cell
building.

Spent
brine
returns
here
from
the
cell
room
after
it
has
been
stripped
of
its
salt
in
the
cells.
The
depleted
brine
flows
into
the
"
diplegs"
where
it
is
resaturated
before
it
is
sent
to
the
filters
on
its
way
back
to
the
cells.

The
Brine
Saturation
System
has
been
retired
for
several
years
but
can
be
reactivated
if
needed.
It
serves
the
same
function
as
the
CP
salt
tank.

24
RAILROAD
YARD
A
significant
portion
of
raw
materials
and
finished
product
is
handled
by
rail.
We
have
six
tracks
in
the
plant
designed
and
laid
out
so
that
shuffling
of
cars
is
possible.
Each
track
serves
its
own
purpose
with
track
#
3
being
the
outward
product
shipment
track.
Southern
Railway
makes
one
switch
daily.
We
perform
other
switching
using
one
of
our
two
Trackmobiles.

25
CHLORINE
LOADING
AND
STORAGE
Liquid
chlorine
may
be
loaded
directly
from
the
process
into
rail
cars
at
loading
stations
#
1
&
#
2
or
stored
in
one
of
four
chlorine
storage
tanks.
Stored
chlorine
will
be
later
loaded
into
railcars
or
shipped
to
customers
through
a
pipeline.

26
INDUSTRIAL
FILTER
The
dirty
backwash
brine
from
the
brine
filters
is
pumped
through
the
industrial
filter
where
it
is
cleaned
up
and
recycled.
The
industrial
filter
must
be
cleaned
daily
after
brine
filter
backwashing
is
completed
and
the
sludge
has
been
removed.

27
HYPO
TANKS
AND
BLEACH
SYSTEM
In
these
tanks
we
create
a
weak
caustic
solution.
This
solution
reacts
with
chlorine
to
form
sodium
hypochlorite
(
hypo).
During
process
upsets,
this
system
will
keep
us
from
emitting
chlorine
to
the
atmosphere.
It
acts
as
a
"
scrubber"
to
remove
chlorine
from
the
process.
Chlorine
gas
from
the
process
can
also
be
added
to
the
caustic
solution
to
increase
the
amount
of
hypo
produced.
The
hypo
is
then
sold
as
bleach.
The
hypo
is
similar
to
the
material
you
purchase
at
the
store
under
the
trade
name
Clorox
®
Bleach,
but
we
manufacture
a
much
stronger
solution.

28
HYDROCHLORIC
ACID
PLANTS
The
original
hydrochloric
acid
plant
was
built
in
1982
to
supply
approximately
3
tons
per
day
of
acid
to
treat
the
brine
system.
Starting
in
1983
some
of
the
acid
was
sold
to
customers.
Various
modifications
and
additions
to
the
basic
equipment
have
been
made
over
the
years
so
that
today
the
original
burner
system
produces
30
tons
per
day
of
A­
6
hydrochloric
acid.
In
1992,
a
near
duplicate
unit
was
added
to
the
west,
giving
us
an
additional
30
tons
per
day
capacity.

The
acid
is
made
by
burning
hydrogen
and
chlorine
together
in
a
furnace.
The
resulting
HCl
vapors
are
then
absorbed
into
purified
water
to
form
a
37%
acid
solution.
The
acid
is
then
piped
to
the
large
white
storage
tanks,
where
it
is
stored
until
it
is
shipped
to
customers
in
either
tank
trucks
or
railcars.

29
COMPRESSION
AND
LIQUEFACTION
Chlorine
gas
is
pulled
from
the
cells
by
two
banks
of
compressors
located
in
this
building
and
pushed
through
two
liquefiers
where
the
chlorine
gas
is
condensed
into
a
liquid.
From
there,
it
proceeds
to
the
loading
and
storage
area.
The
liquefiers
condense
about
99%
of
all
the
chlorine
gas
entering
them.
The
remaining
1%
is
either
absorbed
into
the
inlet
brine
stream
or
sent
to
the
hypo
system.

The
compressor
building
also
houses
the
plant
air
compressors.
They
provide
dry,
compressed
air
for
various
uses
in
the
plant.
This
system
consists
of
two
main
plant
air
compressors,
two
high
pressure
booster
compressors,
one
instrument
air
compressor
and
one
back­
up
diesel
powered
air
compressor.

30
CAUSTIC
AREA
There
are
two
main
caustic
storage
tanks
­­
each
capable
of
holding
250,000
gallons
(
800
tons)
of
caustic
soda.
The
caustic
is
pumped
from
here
into
tank
cars
or
tank
trucks
for
shipment
to
our
customers.

The
two
tall,
narrow
tanks
are
caustic
day
tanks
and
are
dedicated
to
service
for
Federal
Paper
Board.
Caustic
is
pumped
to
Federal
Paper
from
these
tanks
through
a
7,000
foot
long
pipeline.

31
MAINTENANCE

Background
The
Air
Pollution
Prevention
and
Control
Division
(
APPCD)
participated
in
a
major
field
experiment
that
was
conducted
in
February
of
this
year
to
characterize
the
mercury
emissions
from
a
chlor­
alkali
plant
in
Augusta,
GA.
A
tracer
gas,

SF
6,
was
released
at
a
controlled
rate
on
the
cell
building
floor
to
determine
the
total
volumetric
air
flow
from
the
roof
vent
of
the
building.
One
method
used
to
determine
the
concentration
of
SF
6
emitted
from
the
roof
vent
was
open­
path
Fourier
transform
infrared
(
OP/
FTIR)
spectrometry.
Approximately
3000
OP/
FTIR
spectra
were
obtained
over
a
10­
day
monitoring
period.
A
subset
of
these
data
containing
305
spectra
was
analyzed
under
this
work
assignment.

The
primary
objective
of
this
Work
Assignment
was
to
provide

Results

Discussion
2.1
Inspection
of
the
Single­
beam
Spectra
for
Evidence
of
Detector
Saturation
or
Excessive
Stray
Light
Two
steps
that
should
be
completed
during
the
initial
instrument
setup
before
data
are
collected
include
determining
the
distance
at
which
the
detector
becomes
saturated
and
measuring
the
signal
due
to
internal
stray
light.
Apparently,
neither
of
these
two
steps
was
done
during
this
study.
The
ramifications
of
this
oversight
on
the
accuracy
of
the
reported
concentration
data
are
discussed
below.

2.1.1
Determining
the
Distance
to
Detector
Saturation
The
distance
at
which
the
detector
becomes
saturated
determines
the
minimum
pathlength
over
which
quantitative
data
can
be
obtained
with
that
particular
instrument
configuration.
A
procedure
for
determining
this
distance
in
given
in
Section
3.3
of
the
FT­
IR
Open­
Path
Monitoring
Guidance
Document.
Evidence
of
detector
saturation
indicates
that
the
detector
is
not
responding
linearly
to
changes
in
the
incident
light
intensity
and,
therefore,
will
not
respond
linearly
to
changes
in
concentration
of
the
gases
along
the
path.
Detector
saturation
causes
errors
in
how
the
interferogram
is
sampled.

These
errors
can
result
in
aliasing
or
folding
of
spectral
features
outside
the
normal
sampling
frequency
range
into
the
recorded
spectrum.
5
This
effect
gives
rise
to
abnormal
shapes
in
the
single­
beam
spectrum
and
the
appearance
of
non­
physical
energy
in
spectral
regions
where
there
is
no
real
spectral
information.
Because
this
anomalous
information
becomes
part
of
the
recorded
interferogram,
there
is
no
way
to
compensate
for
the
errors
in
the
photometric
accuracy
due
to
detector
saturation.

Once
the
OP/
FTIR
system
is
set
up
along
the
desired
monitoring
pathlength,
a
singlebeam
spectrum
should
be
obtained.
This
spectrum
should
be
inspected
in
the
wave
number
region
below
the
detector
cutoff
frequency.
For
most
MCT
detectors
commonly
B­
4
used
in
OP/
FTIR
applications,
this
cutoff
frequency
occurs
between
650
and
700
cm­
1.

The
instrument
response
in
this
wavenumber
region
should
be
flat
and
at
the
baseline.

An
elevated
baseline
in
this
region
is
due
to
non­
physical
energy
and
indicates
that
the
detector
is
saturated.
If
an
elevated
baseline
is
observed
in
this
region
of
the
single­
beam
spectrum,
the
operator
has
three
choices:

Increase
the
monitoring
pathlength
until
the
instrument
response
is
flat
and
at
the
baseline
in
this
region;

Place
a
wire
mesh
screen
in
the
modulated,
collimated
IR
beam
to
attenuate
the
signal
intensity;
or

Rotate
the
retroreflector
to
reduce
the
signal
intensity.

A
representative
single­
beam
spectrum
from
the
Augusta
field
study
is
shown
in
Figure
1.
This
spectrum
exhibits
evidence
of
nonphysical
energy
in
spectral
regions
that
should
be
flat
and
at
the
baseline,
including
those
below
the
detector
cutoff
frequency
and
in
the
totally
opaque
spectral
regions
between
1400
and
1800
cm­
1
and
3600
and
3900
cm­

1.
This
spectrum
also
exhibits
an
unusual
curvature
in
the
baseline
in
the
2550
to
2850­

cm­
1
region.
As
a
comparison,
a
single­
beam
spectrum
collected
in
Research
Triangle
Park
(
RTP),
NC,
with
an
ETG
OP/
FTIR
system
over
a
414­
m
total
path
is
shown
in
Figure
2.
The
spectrum
collected
in
RTP
over
a
longer
pathlength
exhibits
a
flat
baseline
below
the
detector
cutoff
frequency
and
a
steadily
decreasing
baseline
from
2400
to
3250
cm­
1.

All
of
the
305
spectra
examined
in
the
subset
of
data
collected
during
the
Augusta
study
exhibit
evidence
of
detector
saturation.
Because
of
this
observation,
the
accuracy
of
the
concentration
values
reported
from
this
data
set
is
suspect
and
there
is
no
way
to
assess
errors
in
these
measurements.
In
addition
to
errors
in
the
absolute
concentration
measurements,
changes
in
relative
concentrations
from
one
spectrum
to
another
are
most
likely
nonlinear
and
cannot
be
quoted
with
any
certainty.

2.1.2
Measuring
the
Signal
Due
to
Internal
Stray
Light
Single­
beam
spectra
recorded
with
an
OP/
FTIR
monitor
can
exhibit
a
non­
zero
response
in
wavenumber
regions
in
which
the
atmosphere
is
totally
opaque.
If
the
detector
has
been
determined
to
be
responding
linearly
to
changes
in
the
incident
IR
intensity,
this
non­
zero
response
can
be
attributed
to
internal
stray
light
in
monostatic
instruments
that
use
a
single
telescope
to
transmit
and
receive
the
IR
beam.
The
presence
of
internal
stray
light
causes
errors
in
the
photometric
accuracy,
and
ultimately,
errors
in
the
reported
concentration
values.
The
effects
of
stray
light
on
photometric
accuracy
are
illustrated
in
Section
3.5
of
the
FT­
IR
Open­
Path
Monitoring
Guidance
Document.
If
uncorrected,
the
presence
of
stray
light
results
in
errors
in
the
concentration
measurements
approximately
equal
to
the
percentage
that
the
stray
light
contributes
to
the
total
signal.

Evidence
of
internal
stray
light
is
observed
in
the
single­
beam
spectrum
collected
at
RTP
in
the
CO
2
absorption
region
between
2300
and
2380
cm­
1
(
see
Figure
2).
The
strong
CO
2
absorption
bands
in
this
region
should
extend
completely
to
the
baseline.

However,
in
this
case,
the
presence
of
internal
stray
light
causes
the
apparent
baseline
to
be
elevated.
In
this
particular
instrument,
stray
light
contributed
to
approximately
6%
of
the
total
signal.
No
evidence
of
stray
light
can
be
observed
in
the
single­
beam
spectra
collected
during
the
Augusta
study
(
see
Figure
1).
However,
the
severe
nonlinearity
exhibited
by
these
spectra
prevents
observation
of
the
presence
of
stray
light.
A
singlebeam
spectrum
of
the
internal
stray
light
was
not
supplied
with
this
data
set.
Therefore,

the
effect
of
stray
light
on
the
data
collected
during
the
Augusta
study
cannot
be
determined.
If
stray
light
does
contribute
to
the
total
signal
in
these
spectra,
the
reported
concentration
values
would
contain
errors
proportional
to
the
amount
of
stray
light.

2.2
Measurement
of
the
Signal
Strength
over
Time
and
the
Relative
Signal
Intensities
at
Different
Spectral
Regions
B­
6
The
magnitude
of
the
signal
strength
is
indicative
of
the
performance
of
the
instrument,
i.
e.,
the
output
of
the
source
or
response
of
the
detector,
and
the
alignment
of
the
transmitting/
receiving
telescope
and
the
retroreflector.
The
relative
signal
strength
over
different
spectral
regions
is
also
indicative
of
the
instrument
performance
and
is
influenced,
among
other
factors,
by
the
internal
alignment
of
the
interferometer.
For
example,
if
the
interferometer
is
misaligned,
the
signal
strength
in
the
high
wavenumber
region
will
be
relatively
low.

The
signal
strengths
at
985,
2500,
and
4400
cm­
1
were
measured
in
the
subset
of
305
single­
beam
spectra
collected
during
the
Augusta
study.
The
signal
strength
at
985
cm­
1
is
reported
directly,
whereas
the
signal
strengths
at
2500
and
4400
cm­
1
are
ratioed
to
that
at
985
cm­
1
to
determine
the
relative
signal
strength
in
the
single­
beam
spectra.
Plots
of
the
signal
strength
at
985
cm­
1
and
the
relative
signal
strengths
at
2500
and
4400
cm­
1
for
the
single­
beam
spectra
in
this
subset
are
given
in
Figures
3
 
5.

The
signal
strength
at
985
cm­
1
over
time
is
shown
in
Figure
3.
This
signal
strength
in
arbitrary
units
ranged
from
67.22
to
69.96
with
a
mean
and
standard
deviation
of
68.41
±
0.59,
for
a
relative
standard
deviation
of
0.86%.
The
signal
strength
at
2500
cm­
1
relative
to
that
at
985
cm­
1
ranged
from
a
ratio
of
0.832
to
0.854,
with
a
mean
and
standard
deviation
of
0.842
±
0.005
and
a
relative
standard
deviation
of
0.59%
(
see
Figure
4).
The
signal
strength
at
4400
cm­
1
relative
to
that
at
985
cm­
1
ranged
from
a
ratio
of
0.193
to
0.210,
with
a
mean
and
standard
deviation
of
0.201
±
0.004
and
a
relative
standard
deviation
of
2.0
%
(
see
Figure
5).

The
overall
signal
strength
as
measured
in
the
single­
beam
spectra
at
985
cm­
1
and
the
relative
signal
strengths
measured
at
2500
and
4400
cm­
1
were
nearly
constant
throughout
the
monitoring
period
represented
by
the
305
spectra
analyzed
in
this
subset
of
spectra
from
the
Augusta
study.
These
results
indicate
that
no
significant
changes
in
the
instrument
performance
or
alignment
occurred
during
this
time
period.

2.3
Estimation
of
the
Random
Baseline
Noise
Between
Successive
Data
Files
over
Different
Spectral
Regions
Another
indicator
of
instrument
performance
is
the
random
baseline
noise.
This
noise
is
measured
as
the
root­
mean­
square
(
RMS)
deviation
between
successive
single­
beam
spectra
collected
sequentially
during
a
monitoring
period.
To
make
this
measurement,
a
series
of
absorption
spectra
was
created
from
the
subset
of
single­
beam
spectra
by
using
the
preceding
single­
beam
spectrum
as
the
background
spectrum.
For
example,
spectrum
#
d0224302
was
used
as
the
background
spectrum
for
single­
beam
spectrum
#
d0224303,

and
so
on.
The
RMS
deviation
was
measured
between
958
and
1008
cm­
1,
2480
and
2530
cm­
1,
and
4375
and
4425
cm­
1
and
is
reported
in
absorbance
units.
The
random
baseline
noise
measurements
from
the
subset
of
single­
beam
field
spectra
over
time
are
given
in
Figures
6
 
8.

The
random
baseline
noise
between
958
and
1008
cm­
1
ranged
from
0.111
×
10­
3
to
0.405
×
10­
3
absorbance
units,
with
a
mean
and
standard
deviation
of
0.217
×
10­
3
±
0.053
×
10­
3
(
see
Figure
6).
The
random
baseline
noise
between
2480
and
2530
cm­
1
ranged
from
0.037
×
10­
3
to
0.073
×
10­
3
absorbance
units,
with
a
mean
and
standard
deviation
of
0.056
×
10­
3
±
0.006
×
10­
3
(
see
Figure
7).
The
random
baseline
noise
between
4375
and
4425
cm­
1
ranged
from
0.179
×
10­
3
to
0.368
×
10­
3
absorbance
units,
with
a
mean
and
standard
deviation
of
0.255
×
10­
3
±
0.029
×
10­
3
(
see
Figure
8).

Although
there
was
some
variability
in
the
random
baseline
noise
measurements
(
the
relative
standard
deviations
for
these
measurements
ranged
from
11
to
24%)
there
were
no
obvious
outliers
in
these
data.
The
RMS
noise
levels
in
each
spectral
region
were
within
the
ranges
expected
for
this
type
of
instrument.

2.4
Development
of
a
Synthetic
Background
Spectrum
B­
8
Three
methods
were
used
to
generate
background
(
I
0)
spectra
so
that
the
single­
beam
field
spectra
could
be
converted
to
absorbance
files.
One
method
used
a
field
spectrum
collected
at
the
end
of
the
monitoring
period
that
did
not
contain
any
spectral
features
due
to
SF
6.
This
method
is
similar
to
using
an
upwind
background
spectrum
as
described
in
Section
4.3
of
the
FT­
IR
Open­
Path
Monitoring
Guidance
Document.
File
#
d0224306
was
used
for
these
purposes.
With
this
method,
the
spectral
features
of
the
atmospheric
gases
and
the
instrument
response
essentially
cancel
out,
leaving
only
the
absorption
features
due
to
SF
6.
When
this
is
the
case,
quantitative
data
can
only
be
obtained
for
the
released
tracer
gas.
The
remaining
absorption
features
of
the
atmospheric
gases
represent
the
difference
between
the
concentrations
in
the
other
field
spectra
relative
to
those
in
spectrum
#
d0224306.

The
second
method
used
to
generate
an
I
0
spectrum
was
to
create
a
synthetic
background
spectrum
from
a
representative
field
spectrum.
File
#
d0224306
was
again
used
for
this
purpose.
A
synthetic
background
spectrum
was
created
from
this
file
using
the
method
described
in
Section
4.2
of
the
FT­
IR
Open­
Path
Monitoring
Guidance
Document.
This
synthetic
background
spectrum
was
created
from
650
to
4500
cm­
1
so
that
the
entire
spectrum
could
be
analyzed
for
the
target
gas
and
other
atmospheric
gases.

The
third
method
used
to
generate
an
I
0
spectrum
fitted
a
series
of
segmented
polynomial
curves
to
each
single­
beam
spectrum
as
part
of
an
automated
analysis
method
using
an
innovative
nonlinear
algorithm.
6
No
differences
were
found
in
the
reported
concentrations
of
SF
6
in
the
absorbance
files
created
by
using
either
file
#
d0224306
as
the
background
spectrum
or
the
synthetic
background
spectrum.
The
I
0
spectrum
generated
by
the
nonlinear
algorithm
was
used
only
during
the
nonlinear
analyses
and
was
not
used
to
generate
absorbance
files
for
subsequent
analysis
by
another
method.
All
of
the
concentration
data
reported
from
the
B­
9
Classical
Least
Squares
(
CLS)
analyses
were
computed
from
absorbance
files
created
by
using
a
synthetic
background
spectrum.

2.5
Examination
of
the
Range
of
Absorbance
Values
Exhibited
by
the
SF
6
Spectral
Features
The
tracer
gas
SF
6
has
a
relatively
high
absorption
coefficient
at
the
peak
maximum
at
approximately
948
cm­
1.
Because
of
the
inherent
nonlinear
response
of
an
OP/
FTIR
system
over
a
wide
range
of
absorbance
values,
it
is
imperative
to
determine
the
range
of
absorbance
values
exhibited
in
the
field
spectra.
The
tracer
gas
was
not
detected
in
all
of
the
field
spectra
in
this
subset.
For
those
spectra
in
which
SF
6
was
not
detected,
the
net
absorbance
at
948
cm­
1
was
approximately
0.02
absorbance
units.
This
positive
value
was
due
to
a
small
water
vapor
absorption
band.
The
minimum
net
absorbance
at
948
cm­
1
in
those
spectra
that
did
exhibit
a
detectable
quantity
of
SF
6
was
0.145
absorbance
units.
The
maximum
net
absorbance
for
SF
6
(
0.185)
was
found
for
file
#
d0224291.
The
concentration
of
SF
6
found
in
this
file
exhibited
a
sharp
increase
relative
to
the
concentrations
in
the
other
files
and
did
not
fit
the
trend
exhibited
by
the
preceding
data
files.
For
those
spectra
that
did
fit
the
overall
trend,
the
maximum
net
absorbance
was
0.164
(
file
#
d0224002).
The
range
of
absorbance
values
(
0.145
to
0.185)
observed
for
this
subset
of
data
is
relatively
small
and
should
not
result
in
a
severe
nonlinear
response
in
absorbance
with
respect
to
changes
in
concentration,
assuming
that
the
detector
was
operating
in
a
linear
mode.
B­
10
2.6
Identification
of
Any
Interfering
Species
The
absorption
spectra
that
were
created
using
the
synthetic
background
spectrum
as
I
0
were
visually
inspected
for
interfering
or
unidentified
species.
Only
the
tracer
gas
SF
6
and
common
atmospheric
gases
were
identified
in
the
absorption
spectra.
Water
vapor
was
the
only
interfering
species
that
exhibited
spectral
features
in
the
wavenumber
region
used
to
analyze
for
SF
6.

2.7
Generation
of
Relevant
Reference
Spectra
from
the
HITRAN
Database
Several
reference
spectra
of
selected
atmospheric
gases,
including
CH
4,
N
2
O,
CO,

CO
2,
and
H
2
O,
were
generated
from
the
HITRAN
database
using
Etrans
(
Ontar
Corporation,
North
Andover,
MA).
Spectra
of
the
individual
target
gases
were
originally
generated
at
a
nominal
1­
cm­
1
resolution
with
triangular
apodization
at
a
temperature
of
295K
and
atmospheric
pressure
of
760
Torr.
Each
spectrum
was
generated
at
a
pathlength
of
108
m.
An
absorption
file
compatible
with
Grams/
32
(
Galactic,
Salem,

NH)
was
selected
as
the
output
from
Etrans.
After
the
original
set
of
reference
spectra
were
generated
and
used
in
the
CLS
analysis,
analyses
conducted
by
SpectraSoft
Technology
revealed
that
the
true
resolution
of
the
instrument
was
1.462
cm­
1.
A
new
set
of
reference
spectra
was
generated
at
1.462­
cm­
1
resolution
and
the
CLS
analyses
were
repeated.

2.8
Inspection
of
the
Absorbance
Files
for
Wavenumber
Shifts
and
Changes
in
Resolution
Prior
to
analyzing
the
data
with
the
CLS
methods,
the
reference
spectra
were
compared
to
the
field
absorption
spectra
for
evidence
of
wavenumber
shifts.
If
any
wavenumber
shifts
were
found,
the
reference
spectra
were
adjusted
by
using
the
"
peak
B­
11
align"
subroutine
in
Grams/
32.
The
data
point
density
and
spacing
of
the
reference
and
field
spectra
were
matched
by
using
the
"
interpolate"
routine
in
Grams/
32.

The
innovative
nonlinear
analysis
method
automatically
determines
the
wavenumber
shift
in
the
single­
beam
field
spectra
relative
to
the
reference
spectra
generated
from
Etrans
and
calculates
the
actual
spectral
resolution
of
the
field
spectra.
The
field
spectra
exhibited
a
constant
0.5­
cm­
1
shift
relative
to
the
reference
spectra
generated
from
Etrans.

The
actual
spectral
resolution
was
relatively
constant,
but,
at
a
value
of
1.462
±
0.011
cm­

1,
was
significantly
higher
than
expected
for
an
instrument
operating
at
a
nominal
1­
cm­
1
resolution.
These
data
are
plotted
in
Figure
9
and
imply
that,
although
the
instrument
was
stable,
it
might
not
have
been
operating
properly
initially
at
the
beginning
of
the
field
study.

2.9
Development
and
Evaluation
of
an
Analysis
Method
The
method
used
to
determine
the
concentrations
of
target
gases
from
OP/
FTIR
spectra
should
account
for
the
inherent
nonlinearities
in
the
response
of
the
instrument.

There
are
two
types
of
nonlinearity
that
can
affect
the
accuracy
of
the
concentration
data
reported
by
an
OP/
FTIR
monitor:
detector
nonlinearity
and
nonlinearity
in
absorbance.

Evidence
of
detector
nonlinearity
was
discussed
in
Section
2.1.1
of
this
report
and,

unfortunately,
no
analysis
method
can
account
for
this
type
of
nonlinearity.
The
OP/
FTIR
system
can
also
exhibit
a
nonlinearity
in
the
change
in
absorbance
with
respect
to
changes
in
concentration.
This
nonlinearity
is
due
to
the
convolution
of
the
instrument
line
shape
function,
which
is
influenced
by
the
resolution
and
apodization
used
to
collect
and
process
the
interferograms,
with
the
spectral
data.
The
nonlinearity
with
respect
to
changes
in
absorbance
can
be
accounted
for
by
using
a
multilevel
calibration
model
or
some
other
type
of
nonlinear
analysis
algorithm.
A
multilevel
CLS
analysis
and
an
innovative
nonlinear
algorithm
have
been
previously
applied
successfully
to
APPCD
field
data
collected
at
a
concentrated
swine
production
facility
to
account
for
the
nonlinearity
B­
12
in
the
absorbance
over
the
wide
range
of
concentration­
pathlength
products
of
the
targets
gases
detected
at
that
site.

The
spectral
data
from
the
Augusta
study
were
analyzed
using
four
different
methods.

Three
methods
were
based
on
a
CLS
analysis
using
AutoQuant3
(
MIDAC,
Irvine,
CA),

while
the
fourth
used
an
innovative
nonlinear
algorithm
developed
by
Dr.
Bill
Phillips
of
SpectraSoft
Technology
(
Tullahoma,
TN).
6
A
matrix
of
the
wavenumber
ranges,
target
gases,
and
interfering
species
is
given
in
Table
1.
Different
sets
of
reference
spectra
were
used
for
the
three
CLS
methods.
One
CLS
method
used
a
set
of
reference
spectra
from
the
Hanst
1.0­
cm­
1
spectral
library
(
Infrared
Analysis,
Inc.,
Anaheim,
CA).
Another
CLS
method
used
a
set
of
reference
spectra
of
atmospheric
gases
generated
from
the
HITRAN
database
using
Etrans
and
a
reference
spectrum
of
SF
6
from
the
NIST
Standard
Reference
Database
79
(
Gaithersburg,
MD).
For
this
method,
the
spectra
of
the
atmospheric
gases
were
generated
at
a
concentration­
pathlength
product
that
produced
absorbance
values
of
the
analytical
IR
bands
near
the
median
of
those
found
in
the
field
spectra.
The
third
CLS
method
also
used
a
set
of
reference
spectra
of
the
atmospheric
gases
generated
from
the
HITRAN
database
using
Etrans
and
a
reference
spectrum
of
SF
6
from
the
NIST
database.
A
multilevel
calibration
was
used
for
this
method,
with
reference
spectra
of
the
atmospheric
gases
generated
at
concentration­
pathlength
products
corresponding
to
10%

lower,
10%
higher,
the
median,
and
midpoints
between
the
median
and
the
high
and
low
absorbance
values
of
those
in
the
field
spectra.

As
shown
in
Table
3,
the
reported
values
for
SF6
from
the
multilevel
CLS
analysis
are
very
similar
to
those
determined
by
using
the
comparison
method
for
these
selected
files.
There
is
a
slight
positive
bias
in
the
concentration
values
determined
by
the
comparison
method
because
of
interference
from
a
water
vapor
band.
Otherwise,
the
two
methods
are
comparable
for
these
representative
data
files.

More
extensive
comparisons
were
made
between
the
single­
level
CLS
analyses
using
reference
spectra
from
the
Hanst
spectral
library
and
those
generated
from
Etrans,
the
multilevel
CLS
analysis
with
reference
spectra
generated
from
Etrans,
and
an
analysis
using
the
innovative
nonlinear
algorithm.
Dr.
Phillips
of
SpectraSoft
Technology
performed
the
nonlinear
analysis
under
a
subcontractual
agreement
with
ManTech
under
WA­
IV­
119.
The
concentration
values
of
SF6
and
selected
atmospheric
gases
determined
by
using
the
different
analysis
methods
are
given
in
Attachments

The
mean
concentration
values
reported
from
the
four
different
analysis
methods
are
summarized
in
Table
4.
Also
included
in
Table
4
are
the
results
from
the
original
CLS
analyses
using
reference
spectra
generated
from
Etrans
using
a
nominal
1­

cm­
1
resolution.

The
mean
concentrations
of
SF6
reported
by
each
of
the
analysis
methods
were
nearly
identical
even
though
the
concentration­
pathlength
products
of
the
reference
spectra
for
SF6
were
significantly
different
in
the
single­
level
CLS
method
using
the
Hanst
reference
spectrum
(
66
ppm­
m,
Absmax
=
1.5578)
and
the
other
methods,
which
used
a

spectrum
from
the
NIST

(

two
CLS
methods
using
reference
spectra
generated
from
Etrans
at
1.462­
cm­
1
resolution,
but
were
slightly
higher
for
the
nonlinear
algorithm
and
the
CLS
method
using
the
Hanst
reference
spectra.
There
were
significant
differences
between
the
two
CLS
methods
using
Etrans
reference
spectra
generated
at
either
a
nominal
1­
cm­
1
resolution
or
1.462­
cm­
1
resolution.
In
each
case,
the
CLS
method
using
the
nominal
1­
cm­
1
resolution
Etrans
reference
spectra
under­
reported
the
mean
concentration.

The
mean
concentrations
of
CO
and
N2O
reported
by
the
nonlinear
algorithm
were
slightly
higher
than
those
reported
by
the
CLS
methods
using
the
1.462­
cm­
1
Etrans
reference
spectra,
whereas
the
water
vapor
concentration
reported
by
the
nonlinear
algorithm
was
lower
than
that
reported
by
the
CLS
methods.
The
reasons
for
these
discrepancies
are
not
known,
but
could
include
differences
in
developing
the
synthetic
background
spectrum
for
the
CLS
analyses
and
the
fitted
polynomial
background
for
the
nonlinear
algorithm
or
the
nonlinearity
in
the
data
caused
by
the
saturated
detector.
The
cause
of
these
discrepancies
has
not
been
investigated
further.
The
mean
concentration
for
CO2
reported
from
the
nonlinear
algorithm
was
519.2
ppm,
which
is
slightly
higher
than
normal
ambient
levels.
The
concentration
of
CO2
was
not
reported
for
the
CLS
methods
because
of
the
difficulties
in
analyzing
for
this
gas
in
1­
cm­
1
resolution
spectra
due
to
spectral
overlap
with
CO
and
water
vapor.

Development
of
Relevant
Control
Charts
As
discussed
above
in
Sections
2.2
and
2.3,
control
charts
were
developed
for
the
signal
strength
and
the
random
baseline
noise,
respectively.
Control
charts
were
also
developed
for
the
concentrations
of
selected
atmospheric
gases
over
time.
These
charts
were
developed
from
the
concentration
data
reported
by
the
multilevel
CLS
method
and
are
given
in
Figures
10
 
14.

The
reported
concentrations
of
SF6
fluctuated
between
28
and
50
ppb
throughout
most
of
the
monitoring
period
and
was
relatively
constant
(
38
±
9
ppb)
except
for
a
sharp
increase
that
was
observed
in
files
d0224290
and
d0224291
(
see
Figure
10).
The
concentration
of
SF6
decreased
rapidly
after
file
#
d0224291
and
was
not
detected
in
files
after
d0224300.

The
reported
concentration
of
CH4
was
more
variable,
2.671
±
0.729
ppm
(
see
Figure
11).
The
pathaveraged
concentration
ranged
from
near
or
slightly
below
ambient
background
levels
to
more
than
5.5
ppm.
Although
the
concentration
of
SF6
was
relatively
constant
throughout
the
monitoring
period,
the
CH4
concentrations
increased
rapidly
during
three
separate
episodes.
No
other
gases
exhibited
increases
in
concentrations
during
these
time
periods.

The
path­
averaged
concentration
of
carbon
monoxide
was
relatively
high
(
2.161
±
0.181)
for
ambient
measurements.
High
concentrations
of
CO
were
detected
inside
the
spectrometer
of
the
ETG
system
evaluated
at
RTP,
NC.
The
CO
concentration
in
this
instrument
increased
over
time.
Purging
the
spectrometer
box
with
dry
N2
removed
the
CO
from
the
system.
This
procedure
should
be
done
on
all
ETG
systems
in
the
field.
The
concentration
of
CO
was
relatively
constant,
but
showed
a
steady
increase
near
the
end
of
the
monitoring
period
(
see
Figure
12).

The
concentrations
of
N2O
were
relatively
constant
(
0.348
±
0.010
ppm)
and
slightly
higher
than
expected
ambient
levels
(
see
Figure
13).
Slight
increases
in
the
N2O
concentrations
were
observed
near
the
end
of
the
monitoring
period.
Assuming
that
the
ambient
concentrations
of
N2O
were
constant,
these
results
indicate
that
the
instrument
was
stable
throughout
this
monitoring
period.

As
a
quality
control
check,
the
water
vapor
concentration
was
measured
in
three
different
regions.

Region
1
corresponds
to
the
analysis
region
used
for
SF6
between
900.20
and
980.70
cm­
1;
region
2
corresponds
to
the
analysis
region
used
for
CO
and
N2O
between
2083.90
and
2223.3
cm­
1;
and
region
3
B­
17
corresponds
to
the
analysis
region
used
for
CH4
between
2881.9
and
2929.2
cm­
1.
The
concentrations
of
water
vapor
reported
for
each
region
were
in
close
agreement
and
on
average
were
approximately
14,500
ppm.
This
path­
averaged
concentration
is
equivalent
to
approximately
11
Torr.
If
the
water
vapor
concentration
was
measured
by
some
independent
means
during
the
field
study,
these
data
could
be
used
to
assess
the
accuracy
of
the
OP/
FTIR
data.

3.0
Conclusions
and
Recommendations
The
QC
procedures
used
to
assess
the
instrument
operation
during
the
Augusta
field
study
indicate
that
the
instrument
was
stable
throughout
the
monitoring
period
represented
by
the
subset
of
data
analyzed
for
this
work
assignment.
However,
these
procedures
revealed
significant
problems
in
the
performance
of
the
system
and
in
the
initial
setup
of
the
instrument.
The
single­
beam
field
spectra
exhibited
a
wavenumber
shift
of
0.5
cm­
1
relative
to
the
reference
spectra
generated
from
Etrans.
Also,
the
instrument
resolution
was
calculated
to
be
approximately
1.46
cm­
1,
instead
of
the
selected
value
of
1.0
cm­
1.
In
addition
to
these
problems,
all
of
the
single­
beam
spectra
from
this
subset
of
data
exhibit
evidence
of
detector
saturation.
As
a
result,
the
instrument
was
most
likely
operating
in
a
nonlinear
mode
during
this
study,
which
makes
the
accuracy
of
the
reported
concentration
values
highly
questionable.
Although
different
analysis
methods
and
algorithms
can
be
used
to
account
for
nonlinearities
due
to
the
convolution
of
the
instrument
response
function
on
the
spectral
data,
methods
to
correct
for
the
nonlinearities
due
to
detector
saturation
do
not
exist.
The
likelihood
of
detector
saturation
can
be
minimized
by
examining
the
single­
beam
spectra
during
the
initial
instrument
setup.
Procedures
for
the
initial
instrument
setup
are
given
in
EPA­
sponsored
guidance
documents1,2
and
ASTM
standards.
3,4
These
documents
should
be
reviewed
and
adhered
to
during
future
studies
with
the
OP/
FTIR
system.
In
addition
to
these
documents,
an
example
of
a
USEPA
audit
on
an
OP/
FTIR
field
study,
including
an
extensive
audit
questionnaire,
has
been
presented
and
is
very
helpful
in
applying
many
of
the
operating
principles
and
quality
control
procedures
discussed
in
these
documents
to
OP/
FTIR
field
data.
7
The
comparison
of
the
data
collected
by
the
roof
vent
OP/
FTIR
system
to
those
obtained
by
manual
bag
sampling
with
subsequent
analysis
by
FTIR
spectrometry
is
of
particular
interest
to
the
APPCD.

Because
of
the
uncertainties
in
the
OP/
FTIR
data,
conclusions
drawn
from
this
comparison
should
be
made
with
the
caveat
that
the
OP/
FTIR
instrument
was
most
likely
operating
in
a
nonlinear
mode
due
to
detector
saturation.

MEMO
To:
John
Kinsey
US
EPA,
APPCD
From:
Date:
David
F.

27
September
2000
Subject:
Report
on
the
Analysis
of
Open
Path
FTIR
Data
from
the
Chlor­
Alkali
Plant
Introduction
EPA
supplied
two
open
path
FTIR
data
sets.
The
first
consisted
of
ten
Iomega
®
Zip
disks
that
included
.
spc
files.
These
files
were
single
beam
sample
spectra
collected
by
USEPA
Region
IV
personnel.

The
second
data
set
consisted
of
1
Fujitsu
magneto
optical
(
MO)
disk
that
included
.
spc
files.
These
files
were
absorbance
spectra
"
packed"
as
"
multifiles"
and
consisted
of
upwind
(
background)
spectra
collected
by
USEPA/
APPCD
personnel,
which
had
already
been
processed
from
raw
interferograms
to
absorbance
by
EPA.
The
"
spc"
suffix
indicates
a
data
file
format
used
by
MIDAC,
Galactic
Industries,
and
others
for
spectral
data.

The
processing
steps
consisted
of
obtaining
the
appropriate
software,
file
transfer
and
organization,

packing
the
individual
files
as
multifiles,
conversion
to
absorbance,
unpacking
the
multifiles
to
individual
absorbance
files,
processing
through
the
AutoQuant
®
program,
and
results
organization.
These
steps
are
described
in
the
following
sections.

Obtaining
the
Software
Two
software
packages
were
needed
to
accomplish
this
task:
GRAMS/
32
®
and
AutoQuant
®
.

GRAMS/
32
®
was
needed
for
the
processing
of
the
.
spc
files,
while
AutoQuant
®
is
the
quantification
package.
GRAMS/
32
®
is
a
Galactic
Industries
product
that
may
also
be
obtained
through
MIDAC
Corporation
and
other
instrument
manufacturers.
AutoQuant
®
is
a
MIDAC
Corporation
product.
Both
C­
2
packages
were
obtained
from
MIDAC.
The
"
non­
collect"
version
of
GRAMS/
32
®
was
purchased,
as
this
was
sufficient
for
the
task
and
slightly
less
expensive.

File
Transfer
and
Organization
Sample
spectra
were
obtained
as
.
spc
files
on
10
Zip
disks.
Arcadis
found
that
the
files
were
highly
disorganized
with
many
duplicates
and
files
from
sequential
samples
spread
across
multiple
disks.

In
a
few
cases,
an
individual
file
was
completely
missing.
Many
irrelevant
files,
unknown
purpose,
were
also
included.

The
disks
were
manually
cataloged
to
determine
the
location
of
sequential
sample
files
and
to
identify
missing
files.
A
total
of
1,964
unique
data
files
from
seven
nominal
sampling
dates
were
identified.

Unique
files
were
then
transferred
to
hard
disk
and
organized
in
directories
by
nominal
sampling
date.

These
files
were
then
archived
to
a
recordable
CD
before
any
file
manipulation
was
performed.
The
following
table
describes
the
number
of
sample
files
identified
by
sampling
date.

Packing
Individual
Files
as
Multifiles
The
spectra
were
in
single
beam
format.
While
not
critical,
the
conversion
to
multifile
format
is
a
tremendous
time
saver
prior
to
calculation
of
absorbance
spectra.
The
multifile
format
permits
spectral
arithmetic
operations
to
be
performed
on
all
members
of
a
multifile
with
a
single
command.

The
first
file
manipulation
performed
was,
therefore,
packing
as
multifiles.
GRAMS/
32
®
was
used
for
this
conversion.
As
implemented
there
is
a
limit
of
60
files
that
can
be
packed
into
a
single
file.
For
C­
3
convenience,
50
files
were
placed
in
the
typical
multifile.
These
files
were
named
with
the
sampling
date
prefixes
described
in
Table
1
with
the
addition
of
a
single
letter
suffix
and
then
archived
to
a
separate
subdirectory
on
the
hard
disk.

Conversion
to
Absorbance
Spectra
must
be
converted
to
absorbance
prior
to
any
quantification,
based
upon
the
following
equation:

Abs
log
I
I0
=
 






In
this
equation,
I
refers
to
the
single
beam
spectrum
while
I0
is
a
reference
spectrum.

In
open
path
FTIR,
it
is
difficult
to
obtain
a
true
reference
spectrum.
The
full
optical
path
can
rarely
be
contained
and
purged
of
all
infrared
active
compounds.
A
number
of
techniques
have
been
used
to
generate
a
useful
reference
spectrum.
It
is
sometimes
possible
to
obtain
a
valid
upwind
spectrum
that
is
free
from
the
compounds
of
interest.
Another
technique
calls
for
the
generation
of
a
"
synthetic
background"
spectrum,
usually
by
taking
a
spectrum
and
removing
all
known
spectral
features
from
it.

The
synthetic
background
spectrum
is
often
generated
manually,
though
it
may
also
be
generated
by
fitting
some
function,
for
example
a
spline
function,
to
the
baseline
of
the
single
beam
reference
spectrum.

EPA
supplied
a
synthetic
background
spectrum
for
use
with
this
data
set.
The
generated
multifiles
were
converted
to
absorbance
using
this
reference
spectrum.
The
absorbance
multifiles
were
archived
to
hard
disk
in
separate
subdirectories.

Unpacking
the
Multifiles
to
Individual
Absorbance
Files
Since
AutoQuant
®
cannot
deal
with
absorbance
multifiles
GRAMS/
32
®
was
used
to
separate
multifiles
into
individual
files.
The
individual
files
were
archived
to
hard
disk.
C­

Processing
through
the
AutoQuant
®
Program
AutoQuant
®
requires
one
or
more
"
method"
files,
the
supporting
calibration
spectra
with
concentration
data,
and
sample
absorbance
spectra.
EPA
supplied
three
method
files
and
all
the
associated
calibration
spectra
for
use
in
the
quantification
of
these
data.

In
use,
a
given
method
is
calibrated
with
the
supplied
calibration
spectra
and
then
applied
to
the
selected
spectrum
or
spectra
(
batch
mode).
For
these
calculations,
three
separate
methods
were
needed.

Each
was
applied
sequentially
to
the
selected
set
of
spectra.
Results
are
in
ppm.
Results
were
archived
to
hard
disk
as
.
txt
files.

Organization
of
Results
The
AutoQuant
®
results
were
imported
into
Excel
®
spreadsheets,
1
per
sampling
date,
as
multiple
.
txt
files.
Since
AutoQuant
®
does
not
maintain
the
original
sample
order
in
its
results
file,
results
were
sorted
within
Excel
®
by
sample
name
(
number)
to
restore
the
original
order.

The
original
sample
date
and
time
had
been
"
lost"
(
not
transferred)
by
either
GRAMS/
32
®
during
the
conversions
to
and
from
multifiles
or
AutoQuant
®
.
Examination
of
individual
absorbance
files
within
GRAMS/
32
®
shows
that
the
sampling
date
and
time
are
still
attached
internally
after
all
manipulations
were
completed.
The
original
sampling
date
and
time
were
recovered
by
using
the
DOS
command:
dir
>>

dir.
txt
within
each
of
the
single
beam
subdirectories.
This
ASCII
file
was
then
imported
into
the
Excel
®
spreadsheets
and
aligned
with
the
results
data.
Printouts
of
these
files
are
included
with
this
memo.

Upwind
Data
Separate
from
the
sampling
performed
by
Region
IV
personnel,
upwind
data
were
independently
collected
by
APPCD
personnel
and
equipment.
These
data
were
provided
separately
to
Arcadis.
Arcadis
found
that
all
the
preliminary
data
manipulation
had
already
been
performed
and
that
spectra
already
existed
as
individual
absorbance
files
ready
for
AutoQuant
®
.
Because
these
data
were
collected
on
a
different
instrument
and

different
spectral
resolution,
the
method
files
and
calibration

used
for
the
samples
were
not
appropriate
to
the
upwind
spectra.
EPA
also
provided
the

Quantification
and
results
processing
were
performed
as
described
above
for
the
60
files
generated
on
2/
14/
00.
Examination
of
the
individual
results
revealed
2
sets
of
the
60
that
had
questionable
results
for
one
or
more
compounds.
The
errors
associated
with
these
concentrations
were
much
higher
than
the
other
58
for
the
same
compound.
USEPA
personnel
had
made
the
same
observations
during
calculation
of
this
data
set.
These
two
samples
were,
therefore,
eliminated
after
examining
the
original
spectra
and
results
from
these
two
samples
were
not
used
in
the
calculation
of
average
upwind
concentrations.

The
individual
results
from
the
upwind
samples
were
used
to
calculate
average
concentrations
and
the
standard
deviation.
These
values
were
then
used
to
calculate
a
detection
limit
for
each
compound
based
upon
the
typical
equation:

Detection_
limit
mean
3
*
=
+
 
where
 
is
the
standard
deviation.

Arcadis
used
a
slight
deviation
from
the
above
equation
in
calculating
a
detection
limit
for
SF6.
As
the
Table
2
shows,
both
the
average
and
the
standard
deviation
for
this
compound
are
0.
For
this
compound
only,
Arcadis
used
the
average
error
reported
by
AutoQuant
®
in
place
of
the
standard
deviation.

Of
these,
spectra
from
2/

2000
were
separately
analyzed
by
Mantech;
these
results
were
supplied
by
the

Arcadis
results
were

with
the
Mantech
results.
These

It
can
be
stated
that
differences
are
minor
to
none
and
are

Trendlines
were
established
for
