More About This Title Separation Process Principles- Chemical and Biochemical Operations, 3rd Edition


Separation Process Principles with Applications Using Process Simulator, 3rd Edition is the most comprehensive and up-to-date treatment of the major separation operations in the chemical industry. The 3rd edition focuses on using process simulators to design separation processes and prepares readers for professional practice. Completely rewritten to enhance clarity, this third edition provides engineers with a strong understanding of the field. With the help of an additional co-author, the text presents new information on bioseparations throughout the chapters. A new chapter on mechanical separations covers settling, filtration and centrifugation including mechanical separations in biotechnology and cell lysis. Boxes help highlight fundamental equations. Numerous new examples and exercises are integrated throughout as well.
