An absorber is being used by an industrial company as a gas scrubber. A dilute air-ammonia mixture, containing 5.0mol%NH3 is drawn through the tower countercurrent to an initially ammonia- free water stream. The inlet gas stream rate is 136mol/m2s and the pressure of the absorber, the equilibrium concentrations are related by yNH3=1.075xNH3 If the exiting gas stream is to contain only 0.2mol% ammonia, a) the composition of the exiting liquid stream b) the ratio of the actual Ls/Gs is larger than the minimum Ls/Gs c) the composition of the liquid stream flowing by the gas stream when the gas mixture contains 2.0mol% ammonia
