Acetone is being absorbed by pure water in a packed tower with cross sectional area =0.186m2 at 293K and 1 atm pressure. The inlet gas mbxture of air and acetone contains 2.6 mols acetone, and outlet gas contains 0.5 mol\% acetone. The gas flow rate is 13.65kmol/h, and water flow rate is 45.36kmol/h. Given: kaa=0.0378 kmol/s.m3.mol frac. ka=0.0616kmol/sm3,mol frac. Equilibrium line: y=1.186x (Dilute system: equilibrium line will be straight line following Henry's law) Find: 1- Tower height using k a 2- Tower height using k3a
