A solvent recovery system delivers a gas saturated with benzene (C6H6) vapor that analyzes on a benzene free basis as follows: CO2 - 15%; O2 - 4% and N2 - 81%. This gas is at 21oC and 750 mm Hg pressure. It is compressed to 5 atmospheres and cooled to 21oC after compression. How many kilograms of benzene are condensed by this process per 1000 m3 of the original mixture? Data: Vapor pressure of benzene at 21oC = 75 mm Hg.
