One hundred kmol of 45 mol% acetone, 30 mol% chloroform, and 25 mol% benzene is charged at 101.3 kPa to a batch rectifier consisting of a still-pot, a column containing the equivalent of 10 equilibrium stages, and a total condenser. After establishing a totalreflux condition, the column will begin a sequence of two operating steps, each at a distillate flow rate of 2 kmol/h and a reflux ratio of 10. The durations will be 13.3 hours for Step 1 and 24.2 hours for Step 2. Neglect pressure drops and the liquid holdup. Using a process simulator with UNIFAC (§2.6.9) for liquid-phase activity coefficients, determine the mole-fraction composition and amount in kmol of each of the three cuts.
