Fire Safety Assessment on Blast Simulation Model of Petrochemical Engineering Based on the Most Disadvantageous Point
Based on the traditional research method of safety risk of petrochemical industry in China, the concept of safety capacity is not fully embodied: the principle of the most disadvantageous point was not considered in most cases. The objective of this research is using PHAST software to evaluate the worst case for the explosion risk of Yangpu Economic Development Zone petrochemical enterprises in Hainan based on different explosion mode. The main hazard sources in the zone were analyzed after actual investigation, and then two typical cases were selected: Huizhi Petrochemical 2000 cubic propane storage tank and 160,000 m3 CNOOC natural gas. The fire and explosion accident consequence simulation was carried out regarding on the process and damage area of the explosion accident to the surrounding environment under various explosion modes and different leak diameters. Key findings: (1) the radius of death and serious injury increased with the increase of leak diameters; (2) the death radius (critical injury radius) decreases with the decrease of the leakage concentration and tends to be linear; (3) at the same leakage concentration, the death radius of ME explosion is larger than that of BST explosion, and the vapor cloud explosion mode is larger than that of BLEVE mode.
