Reactive distillation is a process ofsimultaneous reaction and distillation in a single unit in which the reactant and products are continuously separated from the liquid reaction phase into nonreactive vapor phase. In this project, a developed steady-state model of reactive distillation is simulated and modify into dynamic-state model. The dynamic-state model can be used to study the behavior of the column. The reaction involves in this study is a reversible reaction, i.e., esterification of acetic acid and ethanol into ethyl acetate and water. One ofthe reactant is fed in excess to shift the reaction equilibrium to the right. The open loop step change was performed to study the dynamic effects of changing column parameters towards the compositions profile for distillate and bottom. The result obtained was used todetermine the initial controller settings which then can be furthered optimized. Feedback controller is applied to the column using proportional and integral action to counter the disturbance. In the course of applying the feedback controllers, interaction between the possible control loops was studied to identify the best control strategy. From the simulation performed, the control strategy applied seems to provide stable response. From the examination of complete simulation, the model works within the reactive distillation process basis principles. The approach and results from this project is essential for further study involving more complex and rigorous model ofreactive distillation process.
