This research is to study these two important heterogeneous azeotropic separation process. We simulate the system of dehydration of acetic acid in different decanter organic level control strategies and improve the ability of eliminating disturbance. Another dehydration of isopropyl alcohol process, we compare two-column and three-column structures to further purity the top product of the heterogeneous azeotropic column in Chien et al.(1999). After the steady state simulations of two structures, the optimum process designs and operating conditions will be given. The most economical structure for this separation will be recommended. Dynamic simulations of various control strategies for the overall process will be compared.
