Design a distillation column that can effectively separate a mixture of 75% ethanol and 25% water with a feed rate of 1000 kg/hr. Your column should produce a distillate with a composition of at least 95% ethanol and a bottom product with no more than 5% ethanol. Assume the feed mixture enters the column at its boiling point and you have access to a cooling water supply at 20°C for the condenser. Provide a detailed design and justification of your column's operating conditions including temperatures, pressures, and flow rates.
