Gas mixture containing 12.2wt% B and remaining inerts is fed to an absorption tower where it is contacted with liquid solvent A which absorbs B. The mixture is fed at the rate of 32 kg/m3. The wt ratio of solvent to gas entering tower is 3.75: 1.5. The gas leaving the absorber contains 3.5% B, 0.05%A and rest inerts on Wt basis. Calculate. (1) The percentage recovery of solute "B" (ii) Calculate the fraction of solvent fed to column lost in gas leaving the tower, During the process, some solvent evaporates and gets added in gas leaving the tower.
