It is vital for a Chemical Engineer to understand various separation processes and its operations. This book helps the beginners to understand the concepts and its applications in chemical process industries. This book can be used for preparation of GATE and other Competitive Exams and also contains solved examples at the end. The Textbook of Separation Processes helps readers to understand basic concepts and master the separation process including latest processes. The authors have explained key separation processes: Absorption/Stripping, Distillation, Liquid-Liquid Extraction, Leaching, Evaporation, Crystallization and Drying of Solid with exceptional clarity, realistic examples, and case studies. The book starts by reviewing basic concepts, such as equilibrium and unit operations; then introduces a step-by-step process for solving separation problems. Next, it introduces each leading processes, including advanced processes such as supercritical extraction, ionic liquids, membrane separation, reactive extraction, adsorption, biosorption, phytosorption, ion-exchange and chromatography. For each process, the author presents essential principles, techniques, and equations, as well as detailed case studies. Separation Process Engineering is the new, includes improved organization, extensive new coverage, and more than 85% new homework problems and real laboratory schematic experimental setup. Coverage includes: Extensive new coverage of membrane separations, including gas permeation, reverse osmosis, Ultra filtration, evaporation, and key applications; New chapters on-Reactive extraction process are explained with special case studies and real data for easier understanding-A detailed introduction and modeling to sorption's process like adsorption, biosorption and phytosorption, ion exchange and chromatography: everything students need to understand advanced work in these areas;
