It is desired to absorb 95% acetone from a feed mixture of acetone and air containing 2 mol% acetone, using pure water. Pure water at the rate of 800 kg/h is introduced at the top of the tower and the gas flow rate at the bottom of the tower is 450 kg/h. Find the composition of acetone in the liquid effluent flowing out of the tower.
