An absorption tower operates at 093 and at an avere pressure of am water nous down through the column and absorbs so, from a stream howing countercument to the liquid stream. at the top of the tower, the water entering is essentially free of so stream at this plane contains 4mote so ir the liquid-phase mass-transfer coeficient equals 3.4310 k mole/ m a and the asphase mass-transfer coeficiente equals 107-10 kg molem determine the coellicients and at the top of the tower and the sterfacial compositions for the dilute solutions of so, in water ar 293 k the equilibrium mole fraction may be evaluated by yo 3.15 100 y ml aixo
