Air at \(300 \mathrm{~K}\) is used to dry a plastic sheet. The solvent wetting the plastic is acetone. At the end of the dryer, the air leaves containing \(2.0 \mathrm{~mol} \%\) acetone. The acetone is to be recovered by absorption with water in a packed tower. The gas composition is to be reduced to \(0.05 \mathrm{~mol} \%\) acetone. The absorption will be isothermal because of cooling coils inside the tower. For the conditions of the absorber, the equilibrium relationship is \(y_{i}=1.8 x_{i}\). The rich gas enters the tower at a rate of \(0.252 \mathrm{~kg} / \mathrm{s}\), and pure water enters the top at the rate of \(0.34 \mathrm{~kg} / \mathrm{s}\). The tower is packed with 25-mm metal Hiflow rings. Determine the dimensions of the tower. Design for a gas-pressure drop not to exceed \(150 \mathrm{~Pa} / \mathrm{m}\).
