Question 2 22 pts A liquid feed of 150kmol/h benzene-toluene at the boiling point contains 45mol% benzene and the rest toluene. It is being distilled at 101.32kPa to give a distillate with Xp = 0.95 mole fraction benzene and a bottoms of xw = 0.04 mole fraction benzene. Using a reflux ratio of 1.0 determine 1. the number of theoretical trays needed 2. the condenser and reboiler heat loads. [12] [10] Use your enthalpy-concentration diagrams to determine your answers. Useful formulae: Q-Hvi R Hvi-HLO Q' = Hp + Qc Q D = Q" = HW QR W Upload Choose a File Question 2 22 pts A liquid feed of 150kmol/h benzene-toluene at the boiling point contains 45mol% benzene and the rest toluene.
