Separation of Benzene, Toluene and o-xylene using Aspen HYSYS|| how to find reflux ratio & stages

Hi
In this lecture you will learn how to separate Benzene, Toluene and o-Xylene mixture using Aspen HYSYS. We will also determine the reflux ratio, optimal and actual number of stages in distillation columns. Beside it we will find condenser and reboiler duties along with temperature, pressure, k-values plots.
Thanks
