Design a distillation column that can separate a mixture consisting of 40% acetone, 30% methanol, and 30% ethanol with a feed rate of 100 mol/h. The distillate should consist of at least 98% acetone, and the bottom product should contain no more than 1% acetone. You may assume that the column operates at a constant pressure and has 20 equilibrium stages. Determine the reflux ratio and the number of trays required to achieve this separation.
