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 = 0.7, and the liquid product composition is 25 mol % MeOH. Determine the fraction vaporized in the first column, and the values yl, y2, x1, II, and I2. Feed = 10,000 kmol/h Z = 0.55 Column 1 Column 2 L2, X₂ = 0.25/nGiven the vapor-liquid equilibrium data in the table below, Methanol vapor (mol%) 0 13.4 23 30.4 36.5 Methanol liquid (mol%) 0 2 4 6 8 10 15 20 30 40 50 60 70 80 90 95 100 41.8 51.7 57.9 66.5 72.9 77.9 82.5 87 91.5 95.8 97.9 100 Temperature (°C) 100 96.4 93.5 91.2 89.3 87.7 84.4 81.7 78 75.3 73.1 71.2 69.3 67.6 66 65 64.5 Answer the following: Two flash distillation columns are connected together as shown in the following diagram.
