Q1. A mixture of water and ethyl alcohol containing 0.16 mole fraction alcohol is continuously distilled in a plate fractionating column to give a product containing 0.77 mole fraction alcohol and a waste of 0.02 mole fraction alcobol. It's proposed to withdraw 25% of the alcohol in the entering stream as a side stream with a mole fraction of 0.5 alcohol. Find the operating lines for rectifying, intermediate, and stripping sections, if the feed is liquid at the boiling point and RDt=2.0. Q1.
