Design a distillation column to separate a mixture of ethanol and water. The feed stream contains 20 mol% ethanol and the desired distillate should contain at least 95 mol% ethanol. The reflux ratio should be 3:1 and the column should have 25 theoretical trays. Determine the composition of the distillate, bottoms, and the optimal feed tray location to achieve the desired separation. Use McCabe-Thiele method to determine the number of theoretical trays required.
