摘　　要：LPG储罐因为人、设备、生产管理或环境等因素发生泄漏时,遇明火会发生火灾爆炸事故。本文通过对LPG储罐进行危险性分析,针对多类爆炸事故中发生频率高,造成的事故后果严重的沸腾液体扩展蒸汽爆炸(Boiling Liquid Expand Vapor Explosion)进行事故后果计算。本文对某罐区的2个异丁烯储罐、3个丁烷储罐和4个丙烷储罐发生BLEVE进行事故后果分析,并分别计算死亡半径等,根据分析结果提出相应的安全措施。When LPG tanks leak due to human factors,equipment factors,production management or environmental factors,fire and explosion accidents will occur in case of open fire.This paper analyzes the hazard of LPG tank and calculates the accident consequence of Boiling Liquid Expand Vapor Explosion,which occurs frequently in many kinds of Explosion accidents and has serious consequences.In this paper,the accident consequence of BLEVE in Two ISOBUTENE tanks,Three butane tanks and four propane tanks in a tank farm is analyzed,and the death radius is calculated respectively.
