Abstract

In order to improve application effect of HAZOP in chemical operation units, based on the practical experience of its application in modern large chemical plants over the past 10 years, a joint analysis method was proposed. Firstly, behavioral factors of HAZOP participants were studied and process risk attention model was established. Then, its deviation funnel was put forward, possible deviation trends and risk factors of the whole system were identified by using mathematical model before they were manually confirmed and listed into key points of HAZOP. Finally, a HAZOP report was generated by synthesizing various professional resources, and then a method set featuring man￣machine complementarity and layer by layer screening was formed. The results show that the joint analysis method can improve HAZOP sustainability as well as risk identification accuracy of chemical operation units, therefore upgrading safety performance of enterprises. © 2022 China Safety Science Journal.
