A saturated liquid feed of 100 mol/h at the dew point contains equimolar thrichloroethylene and tetrachloroethylene. The mixture is to be fractionated at 101.32 kPa abs to give a distillate containing 85% trichloroethylene and bottoms containing 2% trichloroethylene. The reflux ratio used is 2:1. a. Calculate the amounts and compositions of distillate and bottom products, theoretical number of trays and the feed tray number. b. Determine the actual tray number of trays needed If the Murphree tray efficiency is 0.7 and also calculate the overall tray efficiency. Equilibrium data for Trichlorethylene/Tetrachloroethylene system at 101.325 kPa
