Abstract： The thermal runaway reaction is the main cause of reactive hazards. The sensitive and reliable on-line early warning detection system is another line of defense against accidents that can predict reaction thermal runaway according to the state of reaction system in time and accurately. However, the bottleneck for an on-line detection system is the runaway criterion that distinguishes between dangerous and safe situations. This paper systematically summarized the thermal runaway criteria in on-line warning detection system and its applications in the chemical process, which includes limit check criteria, thermal balance criteria, model-based method, divergence criteria and neural network. Besides, the advantages and disadvantages of various methods were compared when they were used for judging the state of reactions, and the prospect of their application in thermal runaway of chemical reactions was presented.
