Unit Operations of Chemical Engineering, 7th edition continues its lengthy, successful tradition of being one of McGraw-Hill's oldest texts in the Chemical Engineering Series. Since 1956 this text has been the most comprehensive of the introductory, undergraduate, Chemical Engineering titles available. Separate chapters are devoted to each of the principal unit operations, grouped into four sections: fluid mechanics, heat transfer, mass transfer and equilibrium stages, and operations involving particulate solids. Now in its seventh edition, the text still contains its balanced treatment of theory and engineering practice, with many practical illustrative examples included. Almost 30% of the problems have been revised or are new, some of which cover modern topics such as food processing and biotechnology. Other unique topics of this text include diafiltration, adsorption and membrane operations. Salient Features: 1. Balanced treatment of theory and engineering practice, with many practical illustrative examples included 2. New! Section on fluid viscosity in Chap. 3 expanded to include simple theories for gases and liquids 3. Mass-transfer section contains chapters on adsorption and membrane operations 4. Contains up-to-date correlations for heat transfer, mass transfer, and equipment design 5. New! Revised discussion of filter cake washing 6. New! Chapter on Adsorption and Fixed-Bed Separations deals with the use of powdered carbon to treat aqueous waste in tanks, and expanded-bed adsorption that can be used for purification of fermentation broths 7. New! Distillation chapters contain revised sections on flash distillation, flooding limits, and plate efficiency 8. New! Correlations for drying rates and a treatment of dryer thermal efficiency added About the Author WARREN L. McCABE (1899-1982) received his Ph.D. from the University of Michigan. He was successively Vice President and Director of Research of the Flintkote Company, Dean of Engineering at the Polytechnic Institute of Brooklyn, and the R. J. Reynolds Professor in Chemical Engineering at North Carolina State University. He served one term as President of the American Institute of Chemical Engineers. JULIAN C. SMITH (B.Chem., Chem.E., Cornell University) is Professor Emeritus of Chemical Engineering at Cornell University, where he joined the faculty in 1946. He was Director of Continuing Engineering Education at Cornell from 1965 to 1971, and Director of the School of Chemical Engineering from 1975 to 1983. He retired from active teaching in 1986. Before joining the faculty at Cornell, he was employed as a chemical engineer by E.I. duPont de Nemours and Co. He has served as a consultant on process development to Du Pont, American Cyanamid, and many other companies, as well as government agencies. He is a member of the American Chemical Society and a Fellow of the American Institute of Chemical Engineers. PETER HARRIOTT (B. Chem.E., Cornell University, ScD., Massachusetts Institute of Technology) is the Fred H. Rhodes Professor Emeritus of Chemical Engineering at Cornell University. Before joining the Cornell faculty in 1953, he worked as a chemical engineer for E.I. duPont de Nemours and Co. and the General Electric Co. In 1966 he was awarded an NSF Senior Postdoctoral Fellowship for study at the Institute for Catalysis in Lyon, France, and in 1988 he received a DOE fellowship for work at the Pittsburgh Energy Technology Center. Professor Harriott is the author of Process Control and Chemical Reactor Design. He is a member of the American Chemical Society and the American Institute of Chemical Engineers. He has been a consultant to the U.S. Department of Energy and several industrial firms on problems of mass transfer, reactor design, and air pollution control.
