A counter- -flow packed absorption tower is to recover acetone frommixture gas, using water as the absorbing liquid. The tower is 1.0 m indiameter with 25 mm x 25 mm ceramic Raschig rings and the depth ofpacking is 5.0 m, operating at atmospheric pressure and 25"C. The flowrate of gas containing 5% acetone by volume is 2250 m'/h. The exit gascontains 0.26% acetone by volume. The outlet liquid has 60 g acetoneper kilogram water. The equilibrium relationship is y = 2x.· (1) Determine the height of transfer unit HoG and volumetric masstransfer coefficient K,a. v (2) Calculate the amount of acetone recovered per hour.
