Recently polygeneration systems by integrating chemical process and power generation system have attracted more attentions. This paper had described the fundamental research of polygeneration technology carried by the group of author. Firstly, the system integration theory was investigated from the cross level of power and chemical, and the principles of energy cascade utilization and C02 cap- ture was presented. And then, the system integration characteristics and the classification were discussed. The general principles and the corresponding method for system synthesis were summarized. After that, the optimization and design methodologies were setup on basis of energy saving ratio and chemical energy cascade utilization mechanism. Finally, the case study had validated the effectiveness and feasibility of the theory.
