Problem 1: Principles of Unit Operations by Alan Foust
An existing distillation system equivalent to equivalent to eight equilibrium stages is to be used to separate a saturated liquid feed containing 40 mole percent ethanol and 60 mole percent water. The saturated liquid distillate is to have a composition of 80 mole percent ethanol and the saturated liquid bottoms, 10 mole percent ethanol. The system operates at 1 atm pressure with no heat loss at each stage.
(a) Determine the reboiler duty for this operation
(b) What is the percentage recovery of ethanol in the distillate?
