A chemical engineer needs to design a distillation column for the separation of a mixture containing ethanol (boiling point of 78.4°C) and water. The desired composition of the distillate is a minimum of 90% ethanol. What is the minimum number of theoretical trays needed in the column to achieve this composition, given that the feed contains 40% ethanol and the reflux ratio is 1.5?
