Simulation of Distillation of a Large Relative Volatility Mixture

Simulation of Distillation of a Large Relative Volatility Mixture

In this paper, difficulties relating to the simulation of distillation columns for separating mixtures containing components with large relative volatility between the light and heavy key components are discussed. The system used for the study is ethylene o-xylene mixture. The relative volatility is...
