Design a distillation column that separates a mixture of ethanol and water with a 95% ethanol purity and a production rate of 1000 liters per hour. The mixture contains 50% ethanol and 50% water by volume. The distillation column should operate at a pressure of 1 atm and a temperature range of 78-85°C. Assume that the feed enters the column as a saturated liquid and that the overhead product is 90% ethanol, while the bottom product is 5% ethanol. Determine the number of stages required and the reflux ratio for this system.
