Question:

A five-stage countercurrent absorber is used to absorb acetone from air into water at \(3.0 \mathrm{~atm}\) pressure and \(20.0^{\circ} \mathrm{C}\). Total inlet gas flow rate is \(100.0 \mathrm{kmol} / \mathrm{h}\) and is \(0.4 \mathrm{~mol} \%\) acetone. Inlet liquid contains \(0.01 \mathrm{~mol} \%\) acetone. Outlet gas is \(0.02 \mathrm{~mol} \%\) acetone. Assume total liquid and gas flow rates are constant. At \(20.0^{\circ} \mathrm{C}\) Henry's law constant for acetone in water is \(\mathrm{H}=1.186 \mathrm{~atm} /(\mathrm{mole}\) fraction). Find the liquid flow rate required and the mole fraction acetone in the outlet liquid.
