e Rectification of a Heptane - Ethyl Benzene Mixture. A saturated liquid feed of 200 mol/h at the boiling point containing 42 mol % heptane and somoly ethyl benzene is to be fractionated at 101,32 kPa abs to a distillate containing 97mo 17. heptane and a bottoms containing Limol% heptane. The reflux ratio used is 2,5:1. Calculate the mallh distillate, mollh bottoms, the oretical number of trays and actual number of trays, also calculate the feed tray number. Equalibrium data (Table 1) are given below at 101,32 kPa abs pressure for the mole fraction n-heptane and . The percent efficiency is 77").. e Given :- Reflux ratio = 2,5:1 Percent efficiency: 77% Feed = 200 mulle E Table 1: Equilibrium data Temperature K Mole fraction C 1 409.3 136.1 0 0 402.6 129.4 0.00 0.230 3926 119.4 0.250 0.514 383.8 1106 0.485 0.730 376.0 1028 0.790 0.904 371.5 98.3 1.000 1.000
