D13. A distillation column is separating a 30% methanol-70% water feed. The feed rate is 237 kmol/h and is a saturated liquid. The column has a partial reboiler and a partial condenser. We desire a distillate mole fraction of yD.M = 0.95 and a bottoms mole frac- tion of XBM = 0.025. Assume CMO is valid. Data are in Table 2-7 and Problem 3.E1. a. Find N min D14 b. Find (L/V) and (L/D)min" min c. If L/D=2.0 (L/D)min find the optimum feed plate location and the total number of equilibrium stages required. d. Determine the boilup ratio used.
