Spreadsheet 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 point9/8/2009Page 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.
