This paper introduces the research background of inherent safety technology in chemical process, introduces the concept of inherent safety of chemical process and the main design principles of inherent safety technology, summarizes the research progress of five types of inherent safety index evaluation methods and the optimization design of heat exchanger network of inherent safety, and points out the advantages and disadvantages of each inherent safety index evaluation method. This paper focuses on the application of inherently safe design principle in chemical production practice, that is, the optimization design of inherently safe heat exchanger network. At the same time, it is pointed out that the integration of inherent safety principle and heat exchanger network and the establishment of mathematical model for solving the synchronous optimization of inherently safe heat exchanger network are the key points of this technology, which can be used as the research direction in the future.
