Repeat Problem 9.D20 but for a distillation column with 30 stages. Think smart and this problem is less work than Problem 9.D20.

Data From Problem 9.D20.

D20. 10.0 kmole of a 40.0 mol% methanol and 60.0 mol% water

D20. 10.0 kmole of a 40.0 mol% methanol and 60.0 mol% water mixture is batch distilled. The system consists of a column with two equilibrium stages, a still pot (an equilibrium contact), and a total condenser. The system is operated with a reflux ratio L/D = 0.515. The final concentration of methanol in the still pot is XW,final = 0.075. CMO is valid. If you use Simpson's rule, break the area into at least two parts. Find Wfinal, Dtotal, and XD,avg.
