Simulation and Optimization of Divided Wall Column

Abstract

Fully Thermally Coupled Distillation Column for separation of three or more components appear to be more effective in product separation with high purity. It also provide substantial saving in both overall cost and in energy consumption. The simulation of fully thermally coupled distillation column sequences is complex because of greater number of degrees of freedom in comparison to normal distillation technique. The purpose of this study is to simulate fully thermally coupled distillation column and compare the product purity and energy consumption with conventional column. Further with the help of the study of fully thermally coupled distillation column, the concept of Petyluk and divided wall distillation column is also studied. The simulation of fully thermally coupled distillation column is carried out in ASPEN-HYSYS, COCO- Chemsep
