Design a distillation column to separate a mixture of acetone and water containing 35% (by mole) acetone with a feed rate of 1000 kg/hr. The desired purity of the overhead product is 99% acetone, and the bottom product should contain no more than 0.5% acetone. The available reflux ratio is 2.5, and the feed is at its boiling point at normal atmospheric pressure. Determine the number of theoretical trays required, the optimum feed tray location, and the reflux and boilup rates needed for the design.
