Answer the following:
Two flash distillation columns are connected together as shown in the following diagram. 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 V/F= 0.7 , and the liquid product composition is 25 mol% MeOH. Determine the fraction vaporized in the first column, and the values y1, y2, x1, T1, and T2
