Question 2 Rectification of a Heptane-Ethyl Benzene Mixture. A saturated liquid feed of 200 mol/h at the boiling point containing 42 mol % heptane and 58% ethyl benzene is to be fractionated at 101.32 kPa abs to a distillate containing 97 mol % heptane and a bottoms containing 1.1 mol % heptane. The reflux ratio used is 2.5:1. Calculate the mol/h distillate, mol/h bottoms, theoretical number of trays and actual number of trays. Finally, the feed tray number. Equilibrium data (Table 1) are given below at 101.32 kPa abs pressure for the mole fraction n-heptane XHand yh- Note: The percent efficiency is the last 2 digits of your student number (if less than 10, use 10) Table 1: Equilibrium data Temperature Mole fraction K "C XH 409,3 136,1 0 0 402.6 129.4 0.08 0.230 392.6 119.4 0.250 0.514 383,8 110.6 0.485 0.730 376.0 102.8 0.790 0.904 371.5 98,3 1.000 1.000
