Suitable for undergraduate- and graduate-level chemical engineering courses, this classic text is intended for classes focusing on separation processes, mass-transfer operations, unit operations, and distillations. Used in conjunction with a transport phenomena text, 'Separation Processes' will satisfy the unit operations or momentum, heat, and mass transfer core requirements of the chemical engineering curriculum. Professional engineers concerned with the selection and evaluation of alternative separation processes or with the development of computational algorithms will also find this book useful.Topics include simple equilibrium processes, factors influencing product purities, multistage separation processes, patterns of change, group methods, limiting flows and stage requirements, and empirical correlations. Additional subjects include exact methods for computing multicomponent multistage separations, mass-transfer rates, capacity of contacting devices and stage efficiency, and energy requirements and selection of separation processes. Several helpful Appendixes conclude the text. Numerous problems appear throughout the book, and instructors teaching with this book who would like to receive the solutions to the exercises may request them at the following e-mail address: email@example.com.
