Assuming you have a mixture of ethanol and water, design a distillation column that can achieve a 95% purity of ethanol in the distillate using the minimum number of plates possible. The feed to the column contains 40% ethanol and 60% water, and the distillate and bottoms products need to be at least 95% pure. The column operates at atmospheric pressure and the feed rate is 100 kg/hr. Also, determine the reflux ratio required to achieve this separation.
