In a gas mixture containing components A and B, component A is absorbed using a wet wall tower. At a certain point in the tower, the mole fraction of component A in the gas stack is yA0 = 0.15, and the mole fraction of component A in the liquid stack is xA0 = 0.05. Tower 298 K and 101325 kPa operated under pressure conditions. The balance data are as follows; xA 0 0.05 0.10 0.15 0.20 0.25 0.30 0.35 yA 0 0.022 0.052 0.087 0.131 0.187 0.265 0.385 Component diffuses from the gas phase into stagnant B, not back-diffuses from the liquid. . wet wall film mass transfer coefficient for A in the gas phase in correlations used for dilute solutions in towers, k'y = 1.465 x 10-3 kmolA/m2.s. mole fraction and film mass transfer coefficient for A in liquid phase k'x = 1.967 x 10-3 kmolA/m2.s. estimated as a mole fraction. Accordingly, calculate all the mass transfer coefficients Kx and Kx, the flux and the percent resistance in the gas film.
