Mr. Ole Othman <br /> December 10, 1992 <br /> Page 2 <br /> Mass emission rate (lbs/day) is calculated as follows <br /> Ibs = gram * P mole * moles 103mg <br /> day mole mole 106p moles gm <br /> * 1 195 mole * 2 2046 * 10-'Ib * 60min * ft,3 * 24hr <br /> CF@60°F mg hr mm day <br /> or <br /> lbs - pmole * ft3 * 3 83 x 10-4 <br /> day mole min <br /> where gram/mole = molecular weight (assumed to be 100 or C7) <br /> pmole <br /> - PPmav <br /> moleft <br /> 3 = 100 <br /> MM <br /> Concentrations of hydrocarbons m the extracted soil vent gas and catalytic oxidizer outlet <br /> were deternnmed by collecting a tedlar gas bag sample and analyzing the sample(see attached <br /> results) <br /> Brown and Caldwell -0,j,3 <br /> Consultants <br />
