The use of vapor recompression in a complex divided wall column, (DWC) configuration for heterogeneous azeotropic distillation has been shown to provide steady-state economic advantages over conventional designs. The two segregated stripping sections in the DWC are separated by a wall and each has a reboiler. The column has a rectifying section whose overhead vapor is split into two streams. One goes to a condenser. The other goes to a compressor whose high-pressure outlet stream provides heat to one of the reboilers. The other reboiler is heated by steam. The two condensed overhead streams are fed to a decanter. The organic phase is refluxed to the top of the column. The aqueous phase is recycled by combining with the fresh feed. The dynamic controllability of this highly heat integrated and interacting process is studied in this paper. A detailed dynamic simulation is constructed, and an effective control structure is developed that handles large disturbances in throughput and feed composition. The numerical example considers the dehydration of tert-butanol using cyclohexane as the entrainer in heterogeneous azeotropic distillation. (C) 2016 Elsevier B.V. All rights reserved.
