Design a distillation column to separate a mixture of ethanol and water with an initial composition of 40% ethanol and 60% water. The column should achieve a separation of at least 95% ethanol in the distillate product. The available packing materials are Pall rings with a diameter of 1.5 inches and a height of 2 inches. The column inlet flow rate is 1000 kg/hr with a pressure of 1 atm and a temperature of 80°C. The column should have 25 theoretical plates and operate at reflux ratios ranging from 1.5 to 3.0. Additionally, the column diameter should not exceed 3 feet. Provide the design calculations and specifications for the distillation column.

Design a distillation column to separate a mixture of ethanol and water when the initial mixture contains 30% ethanol and 70% water. The desired final concentration of ethanol in the distilled product is 95%. The distillation column is 14 trays high and the reflux ratio is set at 2.2. Calculate the minimum number of theoretical trays required in the distillation column and provide the final composition of the ehtanol product stream.

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.
