Design a distillation column to separate a mixture that contains 40% ethanol and 60% water by weight with a desired ethanol purity of 95%. The feed rate of the mixture is 100 kg/hr and the reflux ratio is 3:1. Determine the number of theoretical plates required and the height of the column. Assume that the total condenser and reboiler are both at 100°C and that the distillate leaving the column is 90% liquid and 10% vapor.
