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.
