Hands-on guidance for the design, control, and operation of
azeotropic distillation systems

Following this book's step-by-step guidance, readers learn to
master tested and proven methods to overcome a major problem in
chemical processing: the distillation and separation of azeotropes.
Practical in focus, the book fully details the design, control, and
operation of azeotropic distillation systems, using rigorous
steady-state and dynamic simulation tools.

Design and Control of Distillation Systems for Separating
Azeotropes is divided into five parts:

* Fundamentals and tools

* Separations without adding other components

* Separations using light entrainer (heterogeneous azeotropic
distillation)

* Separations using heavy entrainer (extractive distillation)

* Other ways for separating azeotropes

The distillation methods presented cover a variety of important
industrial chemical systems, including the processing of biofuels.
For most of these chemical systems, the authors explain how to
achieve economically optimum steady-state designs. Moreover,
readers learn how to implement practical control structures that
provide effective load rejection to manage disturbances in
throughput and feed composition.

Trade-offs between steady-state energy savings and dynamic
controllability are discussed, helping readers design and implement
the distillation system that best meets their particular needs. In
addition, economic and dynamic comparisons between alternative
methods are presented, including an example of azeotropic
distillation versus extractive distillation for the
isopropanol/water system.

With its focus on practical solutions, Design and Control of
Distillation Systems for Separating Azeotropes is ideal for
engineers facing a broad range of azeotropic separation problems.
Moreover, this book is recommended as a supplemental text for
undergraduate and graduate engineering courses in design, control,
mass transfer, and bio-processing.
