' APPENDIX D <br /> • VOLUME-MASS CALCULATIONS OF EXTRACTED GASOLINE HYDROCARBONS <br />' FLAME MINI MART <br /> 1301 West Kettlman Lane, Lodi, Califomla <br />' Assumptions <br /> • Utilizing SVE pilot test analytical data collected from air samples (Table 2) and from field measurements <br /> collected during the pilottest(Table 1),the volume and mass of extracted gasoline hydrocarbons atthe site can <br /> be approximated <br /> The hydrocarbon volume-mass removed during the operating period can be calculated using the following equation <br />' M =C • Q •t <br /> where M =cumulative mass recovered(kg) <br /> C =vapor concentration(kg/m 3) <br /> Q= extraction flow rate (m3/hr) <br />' t=operational period(hrs) <br /> The average Influent TPH-g concentration and average flow rates during each time interval were utilized for calculating <br />' the approximate mass/volume of extracted gasoline hydrocarbons <br /> 12 April 2006 <br /> 1) The average analytical TPH-g concentration for this time interval was determined to be 10,360 µg/1(0902= <br /> 8,400µg/1,1106=12,000µg11,1303=11,000µg11,1504=11,000µg11& 1700=9,400µg/1,avg =10,360µg11 <br /> ' The average flow rate was calculated at 37 5 cubic feet per minute,the operational period was equal to 8 hours <br /> of running time <br /> ' C - 10,360 µg11=0 010360 kg/m3 <br /> Q = 37 5 ft3/mm <br /> t= 8 hours <br /> ' Converting Q to m3/hour yields <br /> Q=(37 5 ft3/min) •(60 min/hour) •(0 0283168m3/ft)=63 71 m3/hour <br /> M =C • Q •t= (0 010360 kg/M3) ■(63 71 m3/hour) • (8 hours) =5 28 kg of gasoline <br /> Converting kg of gasoline to pounds of gasoline yields <br /> 5 28 kg of gas• 2 2046 lbs of gas/kg of gas= 1164 lbs of gasoline <br /> ' Converting pounds of gasoline to gallons of gasoline yields <br /> 11 64 lbs of gas •0 16 gal of gas/lbs of gas = 1 86 gallons of gasoline <br /> l• Advanced GeoEnvironmental,Inc <br /> i <br /> 1 <br />
