Distillation of a binary mixture and comparisons of methods.
We wish to separate a mixture of mol benzene and mol ethylene dichloride in a distillation column with a partial reboiler and a total condenser. The feed rate is and feed is a saturated vapor. We desire a distillate product of mol benzene and a bottoms product that is mol benzene. Reflux is a saturated liquid, and CMO can be used. Equilibrium data can be approximated with an average relative volatility of benzene is more volatile Note: You could also use check Raoult's Law modeling for the system as another source of equilibrium information.
a Find the minimum external reflux ratio.
b Use the Fenske equation to find the number of stages required at total reflux.
c Estimate the total number of stages required for this separation, using the Gilliland correlation for Distillation of a binary mixture and comparisons of methods.
