02) An absorption column, operating at 4.5 bar and 30C, is applied to separate SO2 (A) from air (B) using water as an absorbent. At a particular point in the column, the bulk concentrations of A in the gas and liquid phases are yAG = 0.02 and XAL = 0.0014, respectively. The individual gas-phase and liquid-phase mass transfer coefficients are ky= 15 kmol/(hr)(m)(Ay) and kx = 80 kmol/(h)(m)(Ar), respectively. The equilibrium solubilities of SO2 in water are given in Table Q2.
