Separation Process Engineering, Fifth Edition is a thorough update of the leading textbook for undergraduate chemical engineering core courses in separation methods or in mass transfer and separations. Phillip K. Wankat's proven approach combines quantitative rigor with a tutorial presentation guided by educational principles and the needs of today's learners. Wankat covers all industrially important purification methods in detail, including newer separation methods largely absent from older texts.

Since distillation remains central to most process industries, Wankat thoroughly addresses flash distillation, batch and continuous distillation, multicomponent distillation, extractive and azeotropic distillation, and other techniques, adding valuable new coverage of column flash and cyclic distillation. Readers will also find detailed coverage of other traditional separation methods, including liquid-liquid extraction, absorption, and stripping.

The Fifth Edition contains an entirely new chapter on melt crystallization, as well as extensive coverage of crystallization from solution, adsorption and chromatography, and membrane separations including gas permeation, reverse osmosis, ultrafiltration, pervaporation, and dialysis.

Every chapter starts with summary learning objectives, presents the theoretical basis for each separation, and offers detailed example solutions with practical insights, based on a consistent problem-solving methodology proven to help students succeed. This edition's extensive problem library contains more than 200 new problems, and its hands-on, "learn by doing" appendices have been updated for the latest versions of Aspen Plus and Aspen Chromatography.

Phillip C. Wankat, Clifton L. Lovell Distinguished Professor of Chemical Engineering Emeritus at Purdue University, has served as director of undergraduate degree programs at Purdue’s School of Engineering Education. His research interests include adsorption, large-scale chromatography, simulated moving bed systems, distillation, and improvements in engineering education. His teaching, research, and service awards have included Purdue’s College of Education’s 2007 Distinguished Education Alumni Award, the Morrill award (Purdue University’s highest faculty award), and the 2016 AIChE Warren K. Lewis award.
