Abstract
Explosion load analysis and blast-resistant upgrades for cabinet rooms in liquefied hydrocarbon tank farms are crucial for ensuring safe production in the petrochemical industry.Research on explosion risk as-sessment and upgraded anti-explosion protection was conducted for a typical liquefied hydrocarbon(propylene)tank farm cabinet room.The characteristic values of vapor cloud explosion shock waves in olefin tank farm cabi-net rooms were analyzed using the TNO multi-energy method,and the explosion loads in the cabinet rooms were evaluated based on the explosion pressure characteristics of the gas cloud.Based on the assessed explosion load,the existing cabinet room would be damaged and collapse in an explosion accident.Therefore,an explo-sion-resistant renovation plan was proposed and verified through finite element analysis.The results show that the upgrading and renovation scheme of adding a 200 mm reinforced concrete wall and a 6mm anti-blast coating to the exterior of the blast-facing wall of the existing cabinet room,and spraying a 6 mm blast-resistant coating to the exterior of all other walls,meets the structural safety requirements under explosion loads.The research re-sults can provide references for the risk assessment and blast-resistant upgrades of the cabinet rooms in liquefied hydrocarbon tank farms.关键词
