Ernest J. Henley is Professor of Chemical Engineering at the University of Houston.  He received his B.S. degree from the University of Delaware and his Dr. Eng. Sci. from Columbia University, where he served as a professor from 1953 to 1959.  He has authored or coauthored 72 technical articles and 12 books, the most recent one being Probabilistic Risk Management for Scientists and Engineers.  In 1998, he received the McGraw-Hill Company Award for "Outstanding Personal Achievement in Chemical Engineering", and in 2002, he received the CACHE Award of the ASEE for "recognition of his contribution to the use of computers in chemical engineering education."  He is President of the Henley Foundation.

• Sections on hybrid systems and membrane cascades.
• New material on the design of packed columns, including the fourth generation of random packings, and a discussion on high-capacity trays.

Increased emphasis on the many ways to express composition of chemical mixtures.

• Complete coverage of all separation  processes of commercial importance makes students aware of techniques available to professional engineers
• Unified treatment of the equilibrium-stage and mass-transfer approaches to the understanding, design, and evaluation of separation processes introduces students to the advantages and disadvantages of the two approaches for each separation process.
• Text provides a detailed example of a commercial application for each separation method to demonstrate the importance of the material presented in the text.
• Extensive treatment of real multicomponent systems in addition to systems limited to binary and ternary mixtures exposes students to a wider range of commercial processes.
