AbstractIn recent years process simulation by computer has become an accepted tool in the design and control of chemical processes, but there are still uncertainties and conflicting views about the real benefits relative to cost in both chemical industry and in education.This article surveys the literature of the last three years, exploring the answers to the question: How has chemical process simulation by computer fulfilled expectations in industry and education and what are the major areas of research identifiable at this time?It is concluded that process simulation remains a very dynamic field with a continuous expansion in the areas of application and in the number of users. New subjects requiring research are replacing older areas which have matured.
