Study Of The Performance Of Batch Distillation Using gPROMS

Abstract

The detailed dynamic modelling,and simulation of a batch distillation process is presented. The model considers a mixture of 5 components separated in a 20 tray column. Simulations performed in the process modelling tool gPROMS proved that the model gives a very accurate description of the process behaviour. Overall, gPROMS proved to be a powerful tool for solving problems of large scale models of great complexity such as the batch distillation process. One of the reasons for this is its ability to model and handle discontinuities of the types that very often occurs in chemical processes (for example, when changing the reflux ratio during a distillation operation). As with any other chemical process, the modelling of batch distillation requires the accurate consideration of physical properties in order to model the thermodynamics of the process in an accurate manner.
