Two flash distillation chambers are hooked together. Both are at 1 atm pressure. The feed to the first drum is a binary mixture of methanol and water that is 55% methanol. Feed flow rate is 10,000 kmol/h. The second flash drum operates with (V/F)2 = 0.7 and the liquid composition is 25 mol% methanol. Equilibrium data are given in table [u can use any numbers].
a. What is the friction vaporized in the first flash drum.
b. What are y1, y2, x1, T1 and T2.
