| Summary: | 碩士 === 東海大學 === 化學工程學系研究所 === 86 === A modular approach based on the rigorous dynamic model for heterogeneous azeotropic distillation columns has been developed in this study. An ethanol dehydration system using benzene as entrainer is also explored on the basis of these modules. The dynamic behavior of the heterogeneous azeotropic column is tested by the disturbances of feed flow rate, feed composition,and reflux fraction of aqueous phase in decanter. Also, simulation of the controlled distillation column using classic PI control and PI with feedforward control is studied. Simulation results have demonstrated that the developed modules are workable and they can be reliably used in the further advanced control studies of heterogeneous azeotropic distillation columns.
