$Two flash distillation chambers are hooked together as shown in the diagram. Both are at 1 atm pressure. The feed to the first drum is a binary mixture of methanol and water that is 55 mol% methanol. The feed flow rate is 10,000 kg mol/hr. The second flash drum operates with (V/F)- 07 and the liquid product composition is 25 mol% methanol. VLE data is given below. What is the fraction vaporized in the first flash drum? What are yi, y2, Xi, Ti and T? 4. F10,000kg moles/hr Xp = 0.55 P-1 atm P2=1 atm X2 0.25$
