A chemical engineer needs to separate a mixture of ethanol and water using a distillation column. The feed to the column has 30 mol% ethanol and 70 mol% water, and the desired distillate composition is 95 mol% ethanol. The feed rate is 100 kmol/hour and the reflux ratio is 2. Calculate the number of theoretical trays required in the column to achieve the desired distillate composition.
