Page 18 - Separation process engineering

Acknowledgments

Many people were very helpful in the writing of the first edition. Dr. Marjan Bace and Prof. Joe Calo got
me started writing. A. P. V. Inc., Glitsch Inc., and The Norton Co. kindly provided photographs. Chris
Roesel and Barb Naugle-Hildebrand did the original artwork. The secretarial assistance of Carolyn Blue,
Debra Bowman, Jan Gray, and Becky Weston was essential for completion of the first edition. My
teaching assistants Magdiel Agosto, Chris Buehler, Margret Shay, Sung-Sup Suh, and Narasimhan
Sundaram were very helpful in finding errors. Professors Ron Andres, James Caruthers, Karl T. Chuang,
Alden Emery, and David P. Kessler, and Mr. Charles Gillard were very helpful in reviewing portions of
the text. I also owe a debt to the professors who taught me this material: Lowell Koppel, who started my
interest in separations as an undergraduate; William R. Schowalter, who broadened my horizons beyond
equilibrium staged separations in graduate school; and C. Judson King, who kept my interests alive while
I was a professor and administrator through his articles, book, and personal example.

The assistance of Lee Meadows, Jenni Layne, and Karen Heide in preparing the second edition is
gratefully acknowledged. I thank the reviewers, John Heydweiller, Stewart Slater, and Joe Shaeiwitz, for
their very helpful reviews. The encouragement and occasional prodding from my editor, Bernard
Goodwin, was very helpful in getting me to prepare the long-overdue second edition and kept me from

procrastinating on the third edition.
The assistance of Karen Heide in preparing the third edition is gratefully acknowledged. The hospitality
of the Department of Chemical and Process Engineering at the University of Canterbury, Christchurch,
New Zealand, which gave me time to complete Chapter 15 and an opportunity to teach from the ion
exchange and extraction sections, is greatly appreciated. I thank the reviewers, Ken Morison, Leonard
Pease, David Rockstraw, and Joe Shaeiwitz, for their very helpful reviews. I thank my editor, Bernard
Goodwin, for his continued support and encouragement.

Finally, I could not have finished any of the editions without the love and support of my wife, Dot, and my
children, Chuck and Jennie.
