The absorber should operate at 10 \\\\deg C and atmospheric\ pressure using pure water as the absorbent. If possible, the spent absorbent stream should contain 19.4 mol%\ HCl to meet the product purity requirements. Equilibrium data for absorption of HCl into water is included in the\ textbook problem 12.D8. Determine the flowrates and compositions of the product streams and the number of\ equilibrium absorption stages are required. U
