A total feed of 200 mol/h having an overall composition of 42 mol% heptane and 58 mol% ethyl benzene is to be fractionated at 101.32 kPa abs pressure to give a distillate containing 97 mol% heptane and a bottoms containing 1.1 mol% heptane. The feed enters the tower partially vaporized so that 40 mol% is liquid and 60 mol% is vapor. Equilibrium data are given in the previous problem statement. Calculate the following: (a) Moles per hour distillate and bottoms (b) Minimum reflux ratio (c) Minimum stages at total reflux (d) Theoretical number of trays required for an
