Two instantaneous evaporation chambers are connected, as shown in the diagram. Both work at 1 atm of pressure. The feed to the first tank is a binary mixture of methanol and water containing 55 mol% methanol. The feed flow rate is 10,000 kgmol / h. The second instantaneous evaporation tank works with (V / F) 2a. What is the fraction evaporated in the first instantaneous evaporation tank? B. How much are y = 0.7, and the composition of the liquid product is 25 mol% of methanol. Balance data appear in Table 2-7 1, y2, x1, T1 and T2?
