1. The solute A is being absorbed from a gas mixture of A and B in a wetted-wall tower with the liquid flowing as a film downward along the wall. At a certain point in the tower, the bulk gas concentration YAG-0.25 mol fraction and the bulk liquid concentration is XAL=0.05. The tower is operating at 298 K and 1.013105 Pa, and the equilibrium data are as follows: XA 0 0 0.20 0.131 0.05 0.022 0.25 0.187 0.10 0.052 0.30 0.265 0.15 0.087 0.35 0.385 The solute A diffuses through stagnant B in the gas phase and then through a non-diffusing liquid. ky 1.465 103 kg mol A/s m mol frac. kx 1.967 103 kg mol A/s m - mol frac. Calculate: a) Interface concentrations yi and X and flux NA. b) Overall mass-transfer coefficients Ky, and Ky, and flux NA. c) Overall mass-transfer coefficient K and flux NA.
