Unformatted text preview: e, and low mole fraction regions, the three operating lines are drawn and the equilibrium stages are stepped off so as to place the two feeds at their optimal locations. As seen, the number of equilibrium stages required = just less than 33 equilibrium stages. Call it 32 equilibrium stages in the column and a partial reboiler. Optimal feed stages are located at Stages 17 and 27 from the top. Analysis: (continued) Exercise 7.35 (continued) Analysis: (continued) Exercise 7.35 (continued) Analysis: (continued) Exercise 7.35 (continued) Analysis: (continued) Exercise 7.35 (continued) Exercise 7.36 Subject: Distillation at 1 atm of a mixture of methanol (M) and ethanol (E) to obtain a distillate, bottoms, and a liquid sidestream. Given: 100 kmol/h of a 25 mol% vaporized mixture of 75 mol% methanol in ethanol. Distillate is 96 mol% methanol and bottoms is 5 mol% methanol. Unit consists of a total condenser, plate column, and partial reboiler. Sidestream is 15 kmol/h of 20 mol% methanol. Reflux ratio, R = 1.2 times minimum. Assump...
