MIMM 1 !11111 1 <br /> MASS BALANCE ANALYSIS <br /> operating Parameters: Liquid loading - 1.7 gpm (continuous) <br /> Vapor loading - 90 scfm <br /> Total Nonmethane Hvdro- <br /> carbon concentration - <0.001 ppm <br /> Assumptions: 1) 100 percent transfer of contaminants to vapor <br /> phase <br /> 2) Vapor influent is not contaminated <br /> Mass Balance Equation <br /> (Lin x Nin) + (Vin x Yj.n) = (Lout x Xcut) + (Vout x Yout) <br /> Where, <br /> L = Liquid Loading = 1.7 gpm <br /> X = Contaminant concentration, liquid phase = <0.001 mg/l <br /> V = Vapor Loading = 90 scfm <br /> Y = Contaminant Concentration, vapor phase <br /> and, <br /> Vin = Nout = 0 <br /> Simplifying then, <br /> Vout x Yout = Lin x Xin = Contaminant vapor discharge (lbs/day) <br /> Vout x Yout = <br /> (1.7 gal/min) (<0.001 mg/1) 1am_ x 3.7851 x 1 lb x 1440 min <br /> 1000 mg gal 453.6 gm day <br /> Vout x Yout = <0.00002 lbs da <br /> Rearranging the mass balance equation and solving for the concentration <br /> of nonmethane hydrocarbons in the vapor discharge (Pout) . <br /> Yout = Lin x Xin = 1.7 gal/min x <0.001 mg/1 <br /> --V-O—ut 90 ft�3/min x 7.48 gal/ft <br /> Yout = <0.0000003 mg/1 nonemethane hydrocarbons <br /> GROUND tiATER <br /> TECHNOLOc1;INC. <br />
