[Gas Absorption/Scrubbing] In a plastic manufacturing concern, air is used to dry plastic sheets in which acetone is used as solvent, The acetone in the air is recovered by absorption in pure water in a packed tower. 1000 kg-mol/hr of an air-acetone mixture containing 4 mole% acetone is to be scrubbed to a mixture containing 0.06 mole% acetone. The tower is to be operated such that the kg absorbing water/kg acetone-free air is 1.5. What is the flow rate and composition of the outgoing liquid stream? What is the flow rate of the exit gas stream at 758 mm Hg and 30°C? Neglect the water vapor in the exit gas stream.
