Narrative
Description
and
Process
Flow
Schematic:

3M
Company
utilizes
a
process
known
as
Simons
Electra­
Chemical
Fluorination
(ECF)
to
synthesize
organofluorine
molecules.
In
this
process,
organic
feedstocks
are
dispersed
in
liquid,
anhydrous
hydrogen
fluoride,
and
an
electric
current
is
passed
through
the
solution,
causing
the
hydrogen
atoms
on
the
molecule
to
be
replaced
with
fluorine.
The
predominant
components
of
the
products
created
by
this
process
have
the
same
carbon
skeletal
arrangement
as
the
feedstock
used,
but
with
all
of
the
hydrogen
atoms
replaced
by
fluorine.
However,
fragmentation
and
rearrangement
of
the
carbon
skeleton
can
also
occur
and
significant
amounts
of
cleaved,
branched
and
cyclic
structures
may
be
formed.
The
degree
of
fluorination
of
the
organic
feedstock
is
also
dependent
upon
the
specific
carbon
chain
length
of
the
feedstock
and
parameters
of
the
ECF
process
such
as
electrical
current
and
the
length
of
time
the
process
is
run.
It
is
possible
to
synthesize
fully
fluorinated
or
perfluoroorganic
molecules
where
all
of
the
hydrogen
atoms
of
the
hydrocarbon
feedstock
have
been
replaced
by
fluorine
atoms.
Using
these
perfluoroorganic
molecules
as
basic
building
blocks,
unique
chemistries
can
be
created
by
further
reactions
with
functionalized
hydrocarbon
molecules.

3M
has
produced
sulfonyl
based
fluorochemicals
commercially
for
over
40
years
using
the
ECF
process.
A
basic
building
block
of
such
products
and
the
highest
production
volume
fluorochemical
3M
manufactures
is
perfluorooctanesulfonyl
fluoride
(POSF).
The
starting
feedstock
for
this
reaction
is
1
­octanesulfonyl
fluoride.

The
electrochemical
fluorination
process
yields
about
35%­
40%
straight
chain
(normal)
POSF,
and
a
mixture
of
biproducts
and
waste
of
unknown
and
variable
composition
comprised
of
the
following:

higher
and
lower
straight­
chain
homologs,
i.

n­
CnFzn+
iS02F,
e.
g.,
GFiS02F,
C7F1$

C9F1$

which
comprise
about
7%
of
the
process
output
2)
branched­
chain,
perfluoroalkylsulfonyl
fluorides
with
various
chain
lengths,
about
18­
20%
of
the
output
3)
straight­
chain,
branched,
and
cyclic
(non­
functional)
perfluoroalkanes
and
ethers,
which
comprise
about
20­
25%
of
the
output
4)
"tars"
(high
molecular
weight
fluorochemical
byproducts)
and
other
byproducts,
including
molecular
hydrogen,
which
comprise
about
lo­
15%
of
the
output.

Because
of
slight
differences
in
process
conditions,
raw
materials,
and
equipment,
the
mixture
produced
by
the
electrochemical
fluorination
process
varies
somewhat
from
lot­
to­
lot
and
from
plantto
plant.
The
product
that
results
from
electrochemical
fluorination
is
thus
not
a
pure
chemical
but
rather
a
mix
of
isomers
and
homologues.
The
commercialized
POSF
derived
products
are
a
mixture
of
approximately
70%
linear
POSF
derivatives
and
30%
branched
POSF
derived
impurities.

During
production,
byproducts
and
waste
products
are
formed.
The
volatile
waste
products,
such
as
perfluoromethane,
have
been
vented
to
the
atmosphere
in
the
past,
but
improvements
are
underway
to
capture
and
destroy
these
releases
by
thermal
oxidation.
The
tars
are
incinerated
at
an
in­
house,
hazardous
waste
incinerator.
The
byproducts,
many
of
which
are
incompletely
fluorinated
with
hydrogen
atoms
still
present,
can
be
recycled
back
into
the
ECF
process
or
are
partially
degraded
in
stabilization
processes,
and
discharged
to
controlled,
in­
house,
wastewater
treatment
systems.
The
treatment
sludge
is
either
landfilled
or
land­
incorporated,
Some
of
the
non­
POSF
byproducts
are
recovered
and
sold
for
secondary
uses.

POSF
is
itself
a
commercially
viable
product,
but
is
primarily
an
important
intermediate
in
the
synthesis
of
substances
used
in
many
other
3M
fluorochemical
products.
The
majority
is
used
to
produce
functionally
derivatized
fluorochemicals
and
high
molecular
weight
polymeric
products.

The
perfluorooctane
sulfonic
acid
manufactured
by
hydrolyzing
POSF
intermediates
to
the
sulfonic
acid.
The
various
salts
of
perfluorooctane
sulfonate
are
manufactured
by
base
neutralization
of
the
acid
to
the
appropriate
salt
in
a
batch
reaction.

that

would
not
be

Some
industrial
hygiene
testing
at
Cottage
Grove,
MN
has
shown
the
presence
of
PFOS
in
work
areas,
however
the
industrial
hygiene
personnel
have
indicated
that
this
material
is
believed
to
be
in
the
form
of
dried
particulate
dust.
Although
dispersed
PFOS
has
been
detected
in
the
work
area,
the
concentrations
do
not
indicate
significant
contributions
to
annual
site
air
emissions.

Industrial
hygiene
data
for
PFOS
salts
has
not
been
generated
in
Decatur,
AL
because
they
are
in
a
liquid

Fugitive

for
the

was
conducted
in

1999.

However,
no

Comments:

Although
manufacturing
of
the
salts
listed
on
this
form
is
associated
with
less
than
10
wastewater
discharges
per
year,
the
hydrolysis
of
other
sulfonated
compounds
to
PFOS
in
the
wastewater
treatment
system
result
in
an
ongoing
discharge
of
the
PFOS
compounds.
The
calculated
discharge
amount
therefore
is
not
attributed
to
just
the
salt
production.
A
percentage
of
the
discharges
are
from
the
PFOS
salt
manufacturing.
There
is
not
data
to
distinguish
between
PFOS
discharge
from
PFOS
salt
manufacturing
versus
hydrolysis
of
other
sulfonated
compounds
manufactured
at
this
site
to
PFOS.

PFOS
in
wastewater
discharge
is
not
measured
as
specific
salt
compounds,
but
instead
reflects
the
total
amount
of
dissociated
salts
and
compounds
that
hydrolyze
to
perfluorooctane
sulfonate.

Comments:

In
1997,
land­
amended
sludges
were
held
in
an
impoundment
until
weather
permitted
application
to
the
field.
The
impoundment
is
no
longer
used
as
part
of
the
normal
wastewater
treatment
operation
except
during
equipment
downtime.
A
percentage
of
the
PFOS
land
treatment
is
from
the
PFOS
salt
manufacturing.
There
is
not
data
to
distinguish
between
PFOS
land
treatment
from
PFOS
salt
manufacturing
versus
hydrolysis
of
other
sulfonated
compounds
manufactured
at
this
site
for
PFOS.

The
land
treatment
of
Decatur
sludge
was
discontinued
in
early
1998.
Sludge
now
is
transported
to
an
offsite
landfills,
after
passing
through
a
thickener
and
a
sludge
press.

Estimated
PFOS
levels
in
the
sludge
are
based
upon
the
reduction
of
PFOS
in
the
wastewater
stream
as
it
passes
through
the
clarifiers
at
the
site.
The
PFOS
levels
in
the
sludge
have
been
reduced
by
changes
in
the
amount
of
materials
being
discharged
to
the
sewer.
Wastewater
data
from
1999
show
that
PFOS
levels
in
the
sludge
were
less
than
20,000
pounds
per
year.
