A plant must distill a mixture containing 70 mol% methanol and 30 mole% water. The overhead product is to contain 99 mol% methanol and the bottom product 1 mol% methanol. The feed is at its bubble point, a total condenser is used with a reflux ratio of 1.8 and with the reflux is at its bubble point. A kettle-type partial reboiler is used; the column is operated at 1 atm.
Use the McCabe-Thiele method to determine the number of trays needed to meet process specifications and the optimal location of the feed tray.
Here I assumed equilibrium line...if you take another equilibrium line then number of stages may vary..I hope you understand well... please ask me if you have any doubts..
