Mr. Roland Brooks <br /> January 4, 1995 <br /> Page 2 <br /> Mass emission rate (lbs/day) is calculated as follows: <br /> lbs _ gram * p mole * moles * 103mg <br /> day mole mole 106pmoles gm <br /> * 1.195 mole * 2.2046 * 10-'lb * 60min * ft 3 * 24hr <br /> CF@60°F mg hr min day <br /> or <br /> lbs _ pmole ff3 <br /> - * * 3.83x10-4 <br /> day mole min <br /> where gram/mole = molecular weight (assumed to be 100 or C7) <br /> p mole <br /> - PPmdv <br /> mole <br /> ft <br /> = 100 <br /> min <br /> Concentrations of hydrocarbons in the extracted soil vent gas and catalytic oxidizer outlet <br /> were determined by collecting a tedlar gas bag sample and analyzing the sample (see attached <br /> results). <br /> 1319\CORRESADEC94.RPT <br />
