500 kgmole/hr mutilcomponent mixture with 40% n-hexane, 30% heptanes and 30% n-octane is to be fed to a distillation column. The recovery of n-hexane in the top product is 98% and for the n-heptane in the bottom product is 96%. The column 1.2 atm, 105Cand 60% vaporized feed and reflux ratio is 7.5 The Antoine equation can be applied to each component logpsat (mmHg) = A Component n-hexane n-heptane n-octane A 6.87 6.89 6.92 B 1171.2 1264.9 1352.0 Assume tray spacing 24in specific gravity for liquid -0.7 surface tension 10 dyne/cm 80% flooding and 15% downcomer area.
