. Because of the high concentrations of CO2 found in the influent (2- 5%) , this CO2 represents a significant amount of hydrocarbon removed On average in a hydrocarbon molecule there are 2 Hydrogens (H) for every Carbon (C) therefore each CO2 represents the oxidation of one CH2 radical This indicates hafor Theever molecular oweight recovered one mole of CH2 has been destroyed. of CH2 is 14 gm/mole 14gm/435 6gm/lb= 0 . 032 lb/mole. The volume of one mole of gas at STP = 22 .4 1 1 1 = . 0353 cf 22 . 41 x . 0353 cf/l = 0 79cf/mol . Therefore one cf of pure CO2 represents . 0 . 032 1b/mole '/ 0 79 cf/mole = . 041 lb/cf of CH2 In gasses 1% = 1/100 of a mole . 041lb/cf/100%= 00041 1b/cf/% RESULTS See Table 1 for the results of REMOX operation and Table 2 for results influent/effluent monitoring of the system CONCLUSIONS The VOC emissions during current REMOX operations for the period 10/10/91 to 12/09/92, have not exceeded the 52 lb/day limit . No DCE, TCE or PCE has been detected in the samples The average Natural Gas usage to 7/20/92 was 2 2 cfm, or 3168 cf per operatal day, Gaslusageghasebeenh6n5eof cfm oreunit 9 , 360 an 8/18/92 t he fd, which averagge is av below the permit limit of 17 , 280 cfd.
