Problem 1. Methanol is separated from water using a distillation column with a total condenser. The feed is 50% vaporized and composed of 50% methanol. The feed flow rate is 500kmol/hr and reflux is set to 2 . This process design aims to achieve 95% Methanol in the distillate and 5% Methanol in the bottom. 1.1. If the Murphree vapor efficiency is 50%, how many trays are required? 1.2. When the Murphree vapor efficiency is 50%, what is the tray efficiency? Problem 1.
