It is desired to design a distillation column to separate Methanol and Ethanol. One must obtain 100 kmol / hr of distillate with a mol concentration of 0.95 from a liquid stream saturated with 35 mol% of methanol. For this purpose, there will be a Reboiler and a total capacitor that can eliminate 12000 Kcal / h (λ = 40Kcal / Kmol), and allows a return flow of saturated reflux to the tower. If the concentration of bottom product should not exceed 5 mol% of methanol.
Determine
a) The kmol / hr of food and funds.
b) The number of theoretical stages required.
c) The optimal location of the feeding plate.
The equilibrium curve for the methanol-ethanol system is given by
the following equation:
y = 4x / (1 + 4x)
