Design and Synthesis of Membrane Separation Processes
provides a novel method of design and synthesis for membrane
separation. While the main focus of the book is given to gas
separation and pervaporation membranes, the theory has been
developed in such a way that it is general and valid for any
type of membrane.
The method, which uses a graphical technique, allows one to
calculate and visualize the change in composition of the retentate
(non-permeate) phase. This graphical approach is based on Membrane
Residue Curve Maps. One of the strengths of this approach is that
it is exactly analogous to the method of Residue Curve Maps that
has proved so successful in distillation system synthesis and
design.

Klappentext
A novel approach to the design and synthesis of membrane separations using residue curve maps
Membrane separation processes have seen increased growth in recent years thanks in large part to their reputation as a clean, energy-efficient, and cost-effective technology for selective purification of various chemicals. This breakthrough guide features the latest cutting-edge graphical techniquemembrane residue curve mapsin the design and synthesis of membrane simulations as a way to refine methods in actual separation processes. It guides exploration into these powerful mathematical models and develops the reader's skill in calculating and visualizing the change in composition of the retentate (non-permeate) phase. Though primarily focusing on new discoveries in the less familiarbut rapidly emergingprocesses involving gas separations, Membrane Process Design Using Residue Curve Map applies theory that is adaptable to all types of membranes, including those used in more widely practiced liquid separations. In addition, this book:
-
Provides fundamental methods for the process design and synthesis of membranes
-
Includes a CD that allows the user to input variables for examples and calculations
-
Uses a novel method, membrane residue curve maps, to design and produce membrane systems
-
Applies and adapts the well-known technique for batch distillation in the design of several types of batch and continuous membrane processes as well as membrane/distillation hybrids
Providing comprehensive coverage of basic membrane separation process principles, along with the latest scientific improvements shaping future research, Membrane Process Design Using Residue Curve Maps is an achievement in scientific inventiveness and a reliable companion for chemical professionals exploring new technologies for enhancing liquid and gas separations.
