D8. 10.0 kmol of a feed with x = 0.4 (mole fraction methanol) and the remainder water is sent to a batch distillation system with a large still pot that is an equilibrium contact, a distillation column that acts as two equilibrium contacts (total three equilibrium contacts), and a total condenser. p = 1.0 atm. We operate with a constant XD = 0.8 as we increase L/D. The batch operation is continued until L/D = 4.0. CMO is valid. VLE data are in Table 2-7. Find: a. Xw.final b. We and D. final c.
