Consider the separation by distillation of a chlorination effluent to recover C2H5Cl. The feed is a bubble-point liquid at the column pressure of 240 psia with the following composition and K-values for the column conditions:

Calculate the product distribution, the minimum theoretical stages, the minimum reflux and the theoretical stages at 1.5 times minimum L/D and locate the feed stage. The column is to have a partial condenser and a partial reboiler.
