Subject: FHR Corpus Christi Flaring Information

Brenda, I have attached a lot of information around our flares with some discussion. Take a look at this

and tell me if this is what you were looking for. I have also attached a calculation spreadsheet for a

flaring ev ent at the east refinery (070309 flaring

- loss of calpine.xls). It still has links to our operating

system so make sure you open it with out the automatic calculation option on in excel and don't update it.

We take periodic samples of the gas in the flar e header that is being recovered and then have also

sampled it during worst case events (blowdowns, etc). We try and take a sample during an actual flare

event but if we can't then we default to our worst case numbers based on the plant operating

configur ation at the time.

Call if you have any questions or we can set up a site phone call or visit if that would help clarify.

The East Plant flare flow is calculated in the following manner:

The flow to the 36” Main Flare at the East Plant is calculated by an equation that was developed through

flow measurements in the field and regression fitting of the collected data. The equation for the flow for

the 36” Main Flare is a function of the pressure differential between the square root of the flare header

pressure and the square root of the water seal level. The basic correlation equation is a linear equation

as follows:

y = mx + b

Where:

y = Total flow through 36” Flare (mscf) for each minute

m = is the slope of the regression line which was developed by measuring flow during varying pressure

differential between the flare header and the water seal level, in this case 896.1 (mscfd).

x = ((pressure in the header)^0.5

– (water seal level)^0.5), both the pressure in the header and the water

seal level are in inches of water and are measured continuously by instrumentation in the field which is

used in the calculatio n via the PI System.

b = is the intercept which would then be the minimum flow for a flaring incident; this volume was

conservatively calculated at 15% of the 36” Flare average base load, which for the East Plant 36” Flare is

65.1 (mscfd).

The avera ge base load flow to the 36” flare was determined to be 434,016 SCFD by summing the flow

from the individual units to the 36” flare.

Since the units of the m and b are in mscfd the value calculated is divided by 1440 to give the flow for that

discreet m inute.

# Therefore, the equation for the East Plant with all the values inserted would be the following:

Flow through the 36” Flare/Minute = (896.1 mscfd * ((pressure in the header)^0.5

– (water seal level)^0.5)

+ 65.1 mscfd)/1440

Each discreet mi nute where the flare water seal is exceed for an individual flare is then summed for the

span of the entire event to give the total volume sent to that individual flare (to get the total volume sent to

flaring the volume sent to the individual flares would be summed). Total pounds of individual components

released from a flaring event are calculated using the volume of gas sent to flare, speciation based on the

sampled composition of the gas sent to flare and a combustion factor. For events where a sample is not

obtained a worst case speciation is assumed.

Eric,

Is there any way we could obtain a sample calculation for emissions from a flare water seal break

-- we

really want to understand how your folks estimate flow from the monitoring informat ion you have on the

flare

-- eg., pressure differential. Or, is the calculation done by retracing the water seal break to the event

and using process knowledge of the event, eg., knowing the conditions that caused the water seal break

--

eg., an overpressu re in a vessel, etc.?

BrendaSpreadsheet Note:The spreadsheet is setup to pick up flaring of all flares and during FGRU trip or an exceedance of FGRU pumping capacity (goingto flare caused by upset, shutdown, etc.)For FGRU :E10FI9239.PV read the flow of flare gas recovered and routed to the fuel system.For Flares:E10PC9471.PV reads the pressure of flare header (in H2O)E10LI9220.PV shows the designated water seal level in 1st stage flare K.O. Drum (in H2O).Flow estimation is set at two conditions:If FGRU is in service, the flow rate is estimated with the setup equations for all flares.The average flare base load used in constructing this sheet was 434016 SCFD36" Flow Equation:36" flare flow/minute = 65.1MSCFD+896.91MSCFD(flare pressure^0.5-seal level^0.5)/1440 minutesIf FGRU is down, any off gas discharge to flare header would be flaring at once the water seal is exceeded in the 36" Flareand the last flow rate from E10FI9239.PV would be used as the flaring flow rate until FGRU back in service.The flow rate to the 24" flare is determined by using flow indicator E29FC5134.PV. Any flow on this flow indicator is anidication of flare gas bypassing the fuel system to the 24" flare.The slope (896.91 MSCFD) for the 36" flare is based on the average base load and the average delta P between the flarepressure and the seal level in " H2O for the flaring event starting 1/21/08 and ending 1/22/08The intercept (65.1 MSCFD) for the 36" flare flow calculation is 15% of base load and is used to ensure calculation isconservative from a release stand point7/10/09Page 1of 1 070309 flaring -loss of Calpine.xls DocumentationEast Plant - Flexible LimitsCurrent date and time:7/10/2009 10:22One week ago:7/3/2009 10:22AllowableCAP (lb/hr)Last Wk'sAvg (lb/hr)% of CAPCurrent (lb/hr)% of CAPEPNOXCAP.#1 E.
