Answer #1

Distillation is a process for separation of substances. It takes advantages od boiling point difference.

It is normally carried at a constan pressure.

For a water-methanol mixture:

The advatnage of a water-methanol mixture is that there is NO azeotrope, that is, you can get 100% of pure products separated.

The metanol boils at 64.5°C and water at 100°C; therefore, in the vapor phase (distillate) you find the methanol and at the liquid pahse ( bottoms) the water

I performed a lab experiment for Simple & Fractional Distillation. For simple distillation I got 21.7% of methanol and 78.3% of water. For fractional distillation I got 16.7% of methanol and 83.3% of water. My question is: Did fractional distillation show better separation than simple distillation? Yes or no? I confused in numbers.

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...
