Design a distillation column for the separation of a mixture composed of 50% ethanol and 50% water. The column must produce a distillate that is at least 95% ethanol and a bottoms stream that is at most 5% ethanol. The feed rate is 1000 kg/h and the reflux ratio is to be determined by the student. Provide the complete design of the distillation column including the number of theoretical trays, feed tray location, and the diameter of the column.
