When the book was first published two decades ago, most chemical engineering departments had a required course titled Mass-Transfer Operations. However, now the name of the course has changed in most US universities to Separation Processes; and the name of most of the departments have changed to Chemical and Biochemical Engineering"-- Provided by publisher
