Design a distillation column to separate a mixture of ethanol and water using McCabe-Thiele Method. The feed contains 50 mol% ethanol and the distillate should have a purity of at least 95 mol% ethanol. The reflux ratio is 2.5 and the boil-up ratio is 1.5. The column must have 10 theoretical plates. Determine the number of trays above the feed and below the feed and the corresponding compositions of the distillate and bottoms.
