A benzene-air mixture is to be scrubbed in a simple
countercurrent absorption tower using a nonvolatile
hydrocarbon oil as solvent. The inlet gas contains 5%
benzene and the entering gas flow is 600 Ib moles/hr.
Solubility of benzene in oil follows Raoult's law. The tower
operates isothermally at 80°F. The average molecular
weight of oil is 200 and tower pressure is 1 atm.
