Determine the emissions of benzene in kg day-1 from an oil-water separator given that the area of the separator is 84 m2 , the flowrate of air through the isolation flux chamber is 5 litres min-1 and the area the flux chamber shares with the surface is 0.13 m2 . The benzene concentration in the air leaving the chamber is 0.027 g m-3 . The ambient temperature is 25C.
