Design a distillation column to separate a mixture of ethanol and water when the initial mixture contains 30% ethanol and 70% water. The desired final concentration of ethanol in the distilled product is 95%. The distillation column is 14 trays high and the reflux ratio is set at 2.2. Calculate the minimum number of theoretical trays required in the distillation column and provide the final composition of the ehtanol product stream.
