Adaptive Optimizing Control of an Ideal Reactive Distillation Column

Advanced Control of a Reactive Distillation Column

The paper presents a detailed analysis of the dynamic behavior of a reactive distillation column. A control relevant dynamic model is derived using firstprinciples modeling and it is used to study the dynamic behavior of the process at high and low purity operating regimes. The results are used to analyze the performance of linear and nonlinear model predictive control in comparison to coupled ...

Optimal control of a reactive distillation column

Simulation and Control of an Aromatic Distillation Column

In general, the objective of distillation control is to maintain the desired products quality. In this paper, the performances of different one point control strategies for an aromatic distillation column have been compared through dynamic simulation. These methods are: a) Composition control using measured composition directly. This method sufferes from large sampling delay of measuring de...

Simulation Of Reactive Distillation Column

Reactive distillation processes couple chemical reactions and physical separations into a single unit operation. The ethyl acetate production by esterification reaction is equilibrium limited and is suitable to be carried out in a distillation column. In the present work, a reactive distillation column for the production of ethyl acetate is simulated using Aspen Plus. The component compositions...

Comparative control study of ideal and methyl acetate reactive distillation

The control of an ideal reactive distillation column is compared with that of a similar, but somewhat di2erent, real chemical system, the production of methyl acetate. Similarities and di2erences are observed. Three control structures are evaluated for both systems. A control structure with one internal composition controller and one temperature controller provides e2ective control of both syst...
