Q.2 A saturated liquid feed of 100 kmol/h contains 60 mol % heptane and 40 mol % ethyl benzene is to be fractionated at 101.3
Q.2 A saturated liquid feed of 100 kmol/h contains 60 mol % heptane and 40 mol % ethyl benzene is to be fractionated at 101.3 kPa pressure to give a distillate containing 95 mol % heptane and a bottoms containing 5 mol % heptane. Equilibrium data are given below at 101.3 kPa in terms of mole fractions of heptane. If the Murphree tray efficiency (Emv) is estimated as 0.50: (i) Draw the actual equilibrium curve. (ii) Calculate the actual number of trays. (iii)Calculate the overall column efficiency (Eo). 0.000 0.080 0.250 0.485 y 0.000 0.230 0.504 0.730 x 0.790 0.904 1.000 1.000
