4. A gas mixture containing 17 mole% A and 83 mole % inert is fed to an absorption tower where it is contacted with liquid solvent B which absorbs A. The mole ratio of solvent to gas entering tower is 2:1. The gas leaving the absorber contains 4.5% A, 3.5% B and rest inerts (on mole basis). Find a. The recovery of solute A b. The fraction of solvent B fed to column lost in gas leaving the tower.
