An absorption tower is used to recover benzene from the air. The rate of the feed gas is 100kmols/hr. The feed gas contains 10% mol benzene. Pure heavy oil is at 80 kmol/hr is used as the absorbing liquid. It is desired to attain an exit gas composition of 0.5 mole % benzene at the top of the absorber. What is the composition of the liquid leaving the bottom of the absorber?
