Reactive Distillation Design and Control

Reactive distillation is an economical and environmentally friendly procedure that combines distillation and chemical reaction into a single step. To address the increasing importance of reactive distillation in the petroleum and chemical industries, this book deals with the design of reactive distillation columns and their control systems in an integrated manner.

William L. Luyben, PHD, is Professor of Chemical Engineering at Lehigh University. In addition to forty years of teaching, Dr. Luyben spent nine years as an engineer with Exxon and DuPont. He has written nine books and more than 200 papers. He was the 2004 recipient of the Computing Practice Award from the CAST Division of the AIChE and was elected in 2005 to the Process Automation Hall of Fame. CHENG-CHING YU, PHD, has spent sixteen years as a Professor at National Taiwan University of Science and Technology and four years at National Taiwan University. He has published over 100 technical papers in the areas of plant-wide process control, reactive distillation, control of microelectronic processes, and modeling of fuel cell systems.
