Abstract
Process integration is a system oriented approach to process design of new or retrofitting of existing industrial plants, which applications are focused on resource conservation, pollution prevention and waste management. Some of research institutions reported that "PI is probably the best approach that can be used to obtain significant energy and water savings as well as pollution reductions for different kind of industries". The potential of PI exceeded the results obtained by than traditional audits, based on separate optimization of individual process units. Two key branches of process integration can be recognized as: Energy integration, that deals with the global allocation, generation, and exchange of energy throughout the process and Mass integration that provides a fundamental understanding of the global flow of mass within the process and optimizing the allocation, separation, and generation of streams and species. Specifically, in the past three decades process integration tools are developed for heat integration systems or Heat Exchanger Networks (HENS), mass exchange network (MENS) and reactive mass exchange network (REAMENS), heat-induced separation network (HISENS), energy-induced separation network (EISENS), waste interception and allocation networks (WINS) ,heat-induced waste minimization networks (HIWAMINS) and energy-induced waste minimization networks (EIWAMINS), and membrane separation networks. This paper provides an overview of some of these developments, outlines the major methodology, ideas and objectives, and mark the process integration as an active research area which leads to significant contributions on the engineering principles of integrated systems
