A chemical engineer wants to separate a mixture of ethanol and methanol using a distillation column. The feed to the column contains 30% ethanol and 70% methanol by mole. The engineer wants to obtain a distillate with 80% ethanol and a bottoms product containing no more than 1% ethanol. Determine the number of trays required in the distillation column to achieve this separation. Consider only equilibrium stages and assume that the feed is saturated liquid at its boiling point. The operating pressure of the column is 1 atm.
