Design a distillation column for the separation of a binary mixture of ethanol and water, with a feed consisting of 50 weight percent ethanol and 50 weight percent water. The column should be able to produce a distillate product containing at least 90 weight percent ethanol, with a recovery of at least 95 weight percent of the ethanol in the feed. The feed rate is 1000 kg/hr and the reflux ratio should be optimized for the best separation efficiency. Determine the number of theoretical trays required for the column design and calculate the heat load required for the operation of the column.
