I have probably already done with the top problem but I am not sure. And dont have any idea about the second one which asks for McCabe-Thiele methods.
Problem 11.4-2. 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 give 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 the feed tray number. Equilibrium data are given below at 101.32 kPa abs pressure for the mole fraction n-heptane Xy and you Temperature Temperature K 'C * Y K C *N Yw 409.3 402.6 392.6 136.1 129.4 119.4 0 0.08 0.250 0 0.230 0.514 383.8 376.0 371.5 110.6 102.8 98.3 0.485 0.790 1.000 0.730 0.904 1.000 Problem 11.4-4. Minimum Number of Theoretical Plates and Minimum Reflux Ratio. Determine the minimum reflux ration R.and the minimum number of theoretical plates at total reflux for the rectification of a mixture of heptane and ethyl benzene as given in Problem 11.4-2. Do this by the graphical methods of McCabe-Thiele.
