Abstract:Stream power system(SPS),which consumes the primary energy(coal etc.) to generate stream,electricity,mechanical power and the refrigerant,plays a vital role in process system. Design and optimization of SPS should not only consider the flexibility to deal with the process from internal and external changes,but also to weigh the system of economic,environmental and other indicators to adapt to sustainable development. The flexibility and multi-criteria design of SPS have become the focus of process integration research. Initially,in this paper the research progress of design and optimization methods of SPS,heuristic method(i.e.,the experience method),the thermodynamic target method,the mathematical programming method or the combination of them for example,were summarized. Moreover,the research situation of the flexible design of the SPS under the condition of certainty and uncertainty were analyzed. Finally,in past 10 years,multi-objective optimization design of SPS considering the economic,environmental,exergetic and other objectives and the cogeneration and renewable energy driven SPS were emphasized. Research showed that it is the focus of future that simultaneous synthesis of SPS with chemical processes and heat exchanger network consider a variety of energy driven,flexibility,multi-objective optimization.
