<br /> REPORTING PERIOD: July 12,2010 to September 15,2010
<br /> Period Operation(hours): 1,178.6
<br /> Period Operational(%): 51%
<br /> Historical%Operational 77%
<br /> Definitions:
<br /> °F=Degrees Fahrenheit FID=Flame Ionization Detector
<br /> inHg=Inches of mercury VOC=Volatile Organic Compounds
<br /> acfm=Actual cubic feet per minute ppmv=Parts per million by volume
<br /> [ ]=Indicates reference to equation SJVAPCD=San Joaquin Valley Air Pollution Control District
<br /> scfm=Standard cubic feet per minute ATC=Authority to Construct
<br /> Notes:
<br /> -Column under heading VOC(Hexane)Removed(Ib/day)added 2Q10 to track removal rate of total VOCs.
<br /> a=VOC reported as Hexane(molecular weight 86.17)for VOC vapor mass removal rate calculation.
<br /> Hexane was used because it was most representative of the lower carbon range organics.
<br /> b=System inspected by the air board and started on 5/31/2007.
<br /> c=Vapor flow data collected as SCFM.
<br /> d=Flow rate(acfm)derived from Roots 59 curve with temperature being the average for the system.
<br /> Equations:
<br /> [1] ACFM•T (Pt [2]VOC Removed (Ib/day)
<br /> (460+T
<br /> SCFM = )-TO,. removal rate=influent VOC -effluent VOC
<br /> Tam =Temperature at standard conditions(528 Rankine)
<br /> Pabs=Atmospheric pressure at standard conditions minus manifold
<br /> vacuum(inHg)
<br /> Patr =Atmospheric pressure at standard conditions(29.92 inHg)
<br /> T =Manifold vapor temperature reading(°F)
<br /> Permits:
<br /> Air emissions are permitted under SJVAPCD ATC Number N-4878-2-0.
