Problem 4. A two phase mixture containing 40 mole % methanol

Problem 4. A two phase mixture containing 40 mole % methanol (M) and 60 mole % water (W) is continuously fed into a distillation column operating at 1 atm. The system has a partial condenser and a partial reboiler. The desired separation requires 23 equilibrium stages including the partial condenser and the partial reboiler, and the optimum feed stage is 7 stages below the condenser. That is, if the stage immediately below the condenser is numbered as Stage 1, then the optimum feed stage is Stage 7. The overall efficiency is Eo = 0.70 for this case. a. Determine the actual number of stages required. b. Determine the actual feed stage. For both (a) and (b) be careful to state whether or not the condenser and reboiler are included in the number of stages
