Abstract
The separation performances of ideal mixture (n-hexane and n-heptane) were evaluated by using the commercial software simulator called HYSYS in the conventional distillation column and the feed splitting column. The optimum conditions of stage number and reflux ratio can be pointed out from the simulation results. To obtain a better separation performance, the stage number should be increased while having a low reflux or vice versa. From the result of conventional column, the condition of minimum reflux ratio was visualized. Moreover, the composition profiles of those two columns were performed with the variations of stage number, reflux ratio and the second feed location in feed splitting column in order to find the proper criteria.
