Abstract:
Due to the successful experience gained in the process intensification and implementation of Reactive Distillation and Divided Wall Column in industry, Reactive Divided Wall Column have also been considered as a further step in process intensification. One important research area in implementation of RDWCs is their control issue. In the present study, the dynamic simulation of reactive divided wall columns and their control were studied and the adaptive model predictive control was used for the control objectives. Aspen Dynamics software was used for simulation and MATLAB software was utilized for applying the control strategy. The advantage of the applied control method is the use of input-output transfer function. In this control method, only the input and output of the system are required to be measured, and with the help of the least squares method, the parameters of the system model are updated. The effectiveness of the applied control method was demonstrated through simulation study
