DYNAMIC SIMULATION OF BINARY DISTILLATION PROCESS

Abstract

The available models of Distillation Column of different complexities are studied. A multi-stage binary column and a multi-component multi-stage distillation column have been simulated separately. The simulation of binary distillation column assumes constant Murphree vapour efficiency, however the simulation of multi-component distillation column expects it as an input variable. Both the simulations are amalgamated in a menu driven user friendly software developed in C++ as the part of this dissertation. Also facility is provided in the above-developed software to observe various desired characteristics like concentration of distillate with respect to time, sample tray concentration with respect to time and tray temperature with respect to time for selected tray etc. For the simulation of distillation process rigorous model is considered. The simulation model has been tested for the binary mixture and the multi-component mixture reported in Luyben [15]. Results obtained by above simulation coincide with the results reported.
