An absorber is being used by an industrial company as a gas scrubber. A dilute air-ammonia mixture, containing 5.0 mol% NH₃ is drawn through the tower countercurrent to an initially ammonia free water stream. The inlet gas stream rate is 136 mol/m².s and the inlet NH₃ -free water rate is 3.4 kg/m².s. At the temperature and pressure of the absorber, the equilibrium concentrations are related by

y_NH3 = 1.075 x_NH3

If the exiting gas stream is to contain only 0.2 mol % ammonia, determine

a. the composition of the exiting liquid stream;

b. the ratio of the actual L_s/G_s is larger than the minimum L_s/G_s.

c. the composition of the liquid stream flowing by the gas stream when the gas mixture contains 2.0 mol % ammonia.
