Operability Analysis of MTBE Reactive Distillation Column using a Process Simulator

Reactive Distillation Process Analysis in a Divided Wall Column

This contribution aims to present a methodology to model and simulate the reactive dividing wall column (RDWC) using commercial software. Feasibility of separation scheme was established with ASPEN DISTILTM. Simulation of flowsheet configuration was performed with ASPEN HYSYSTM, using the two columns model. The reactive zone hosted by the prefractionator was modelled and simulated as backward f...

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...

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

Fuzzy Hybrid Modeling of a Reactive Distillation Column for Ethyl Acetate Process

The complex interactions between vapour-liquid equilibrium, mass and energy transports and reaction kinetics in reactive distillation (RD) process have constituted serious computational challenges to its modelling and control. This is because large numbers of nonlinear differential algebraic equations are needed to represent the process when using first principle modelling approach. This work d...
