Separation Process Engineering, Fourth Edition, offers student- and faculty-friendly coverage of all currently important methods for chemical engineering separation. It teaches via detailed examples, using real data to solve real engineering problems, all organized in a common format to streamline learning. This edition also provides new homework problems, spreadsheet-based exercises, and well-tested, laboratory-style computer simulations that make it far easier to teach an up-to-date course. Earlier editions focused on classical chemical engineering separations of distillation, absorption, stripping and extraction. These remain important, but this new edition has expanded coverage to include newer methods. The fourth edition's extensive coverage and realistic examples also encompass these industrially important techniques: flash distillation; continuous column distillation, including extractive and azeotropic distillation; batch distillation; membrane separations, adsorption, ion exchange, and chromatography. This edition also adds an entirely new chapter on crystallization, including population balances and pharmaceutical applications. Updated throughout for the latest research, this fourth edition also incorporates expanded coverage of the fundamentals of mass transfer, together with a broader range of problems. This enables chemical engineering programs to teach mass transfer from the same textbook they use for separations.
