Design and control of distillation systems for separating azeotropes

This book studies a broad spectrum of azeotropic distillation separation methods for a variety of industrially important chemical systems. First economically optimum rigorous steady-state designs are developed for each chemical system. Then practical control structures are developed that provide effective loadrejection in the face of disturbances in throughput and feed composition. Thethree types of azeotropic separation systems are illustrated for a number of chemical systems: ethanol/water; THF/water, isopropanol/water, acetone/methanol, isobutane/methanol, n-butanol/water and acetic acid/water. Economic steady-state designs are developed that minimize total annual cost of both capital and energy. Then conventional PI control structures are tested for their abilityto maintain product quality during disturbances. Economic and dynamic comparison between alternative methods are presented for some of the chemical systems, for example azeotropic distillation versus extractive distillation for the isopropanol/water system.William L. Luyben, PhD, is a professor at Lehigh University, and the author/co-author of 11 textbooks. He has published over 220 technical papers in the area of process control and design (8 in the area of azeotropic distillation alone). He has nine years of industrial experience with Exxon and DuPont. I-Lung Chien, PhD, has published over 50 technical papers in the area of process control and design, 14 of which were in the area of azeotropic distillation. He was the senior consulting engineer for DuPont Engineering for eight years, and has done research in chemical, polymer and bio processing.
