Integrated process hazard analysis method and system and storage medium

Abstract

The invention discloses an integrated process hazard analysis method, an integrated process hazard analysis system and a storage medium. The method comprises the following steps: acquiring reasons causing deviation and causing deviation in different production states; correcting and calculating the potential probability of the unexpected event according to the probability of a deviation reason, anenabling event and condition; generating a consequence severity level of the unexpected event according to the reason of the deviation and the consequence severity matrix; performing preventive measure action on the unexpected event according to the potential risk level; obtaining the residual probability of the unexpected event after the preventive measure action is implemented; performing protective measure action on the unexpected event according to the potential risk level; obtaining the severity level of the residual consequence of the unexpected event after the protective measure actionis implemented; and generating a residual risk level according to the residual probability of the unexpected event, the residual consequence severity and the risk matrix. The defects of a traditionalanalysis method are effectively avoided.

Description

Technical field [0001] The invention belongs to the field of chemical production, and specifically relates to an integrated process hazard analysis method, system and storage medium. Background technique [0002] In recent years, with the rapid development of industrialization, especially the development of high-risk industries such as chemical and pharmaceutical industries, catastrophic accidents have occurred from time to time, such as the particularly major fire and explosion accident in Ruihai, Tianjin in 2015, and Xiangshui, Yancheng in 2019. A particularly major fire and explosion accident, and a major explosion accident in Shenghua, Zhangjiakou, Hebei in 2018. In order to avoid the occurrence of such catastrophic accidents, scientific methods are needed to identify and evaluate the process hazards of such high-risk industries, including a comprehensive system for new and expanded projects under design and in-service medical and chemical equipment. Process hazard identific...
