Both are at 1 atm. The feed to the first drum is a binary mixture of methanol and water of 55 mol% MeOH. Feed flow rate is 10,000 kmol/h. The second flash column operates with = 0.7, and the liquid product composition is 25 mol% MeOH. Determine the fraction vaporized in the first column, and the values yl, y2, xI, TI, and T2. V2 EE Feed 10,000 kmol/h Column 1 ZF = 0.55 Column 2 L2, x2 = 0.25
