Spreadsheet Note:

The spreadsheet is setup to pick up flaring of all flares and during FGRU trip or an exceedance of FGRU pumping capacity (going to flare caused by uFor 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" Flare and 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 an idication 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 flare pressure 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 is conservative from a release stand point

* Use 701FCD sample on the "36 Inch Flare" sheet.* Use 714FSF sample on the "24 Inch Flare" sheet. If not available use 721 MFD.* If in the sample results ppmv is used as a unit of measure the unit will need to be converted to mol% for the purposes of the calculation* For all species of butanes, butenes, hexanes, pentanes and octanes aggregate the total for each family for a RQ determination.* If a smoking flare is noticed adjust the destruction efficiency on the flare calcs to account for incomplete combustion (normally 98%, if smoking adjust to 93%).* TCEQ Technical Supplement 4 for flare (TCEQ publication RG-360A) recommends 93% destruction efficiency for smoking flares.
