Hi-Gee Chemical Separation Engineering introduces the basic concepts and technical terms of high gravity (hi-gee) separation technology in a systematical way while also analyzing and expounding on the differences between centrifugal separation technology and high gravity separation technology. The book takes the "problem elicitation-theory-principle-key technology-application case" as the main line and introduces, in detail, the operation and technical contents of high gravity chemical separation, such as absorption, desorption, distillation, extraction and adsorption. In addition, the book highlights academic innovation and lists examples that are closely combined with practical production. This book will be an indispensable reference for researchers, engineers and technicians, production managers, and teachers and students of related majors in colleges and universities in chemical industry, materials, environment, pharmacy, food and other fields.
