Design a distillation column that can effectively separate a mixture of ethanol and water with a composition of 60% ethanol and 40% water. The distillation column should have a reflux ratio of 1.5 and a total of 10 theoretical stages. Determine the operating conditions (temperature, pressure, and feed rate) needed to achieve a distillate product with a composition of 95% ethanol and a bottoms product with a composition of 5% ethanol.
