Using a process simulator, compare the energy required to recover ethanol from the following two mixtures and target 80% molar composition (minimum) in the distillate containing the ethanol:

1. 10% Ethanol90% Water, 50 kg/s at 32
C.

2. 20% Methanol, 50% Ethanol, 20% Propanol, 10% Butanol, 10 kg/s at its boiling point.
