D4. A partial condenser takes vapor leaving the top of a distillation column and condenses a portion of it. The vapor portion of mole fraction yD is removed as the distillate product. The liquid portion of mole fraction x0 is retumed to the column as reflux. The liquid and vapor leaving the partial condenser can be assumed to be in equilibrium. A distillation column with a partial condenser and a partial reboiler is separating 100.0kmol/h of saturated liquid feed that is 30.0 mol% methanol and 70.0mol% water. Column pressure is 1.0atm. We desire a 99.0% recovery of the methanol in the vapor distillate and a 98.0% recovery of water in the bottoms. Equilibrium data are in Table 2-7 (in Problem 2.D1), and other data are in Problem 3.E1. Find D,B,yD,M, and xB,M. If L/D=2.0, find x0,M, flow rate L0 of the reflux stream, Qc, and QR. I able 2t.
