SAFETI在LPG储罐事故后果评价中的应用

分析了LPG危险特性及LPG储罐潜在的火灾爆炸危险性,运用SAFETI软件对某LPG储罐区的各类重大事故后果进行了定量评价,建立了针对性强的事故后果模型.该模型能客观准确地模拟与预测重大事故后果,获得事故危害程度的计算机模拟图表和报告等结果,可提供预测、预防事故发生的措施.

Application Research of SAFETI on the Fatal Accident Consequence Assessment in LPG Storage Tanks

Based on the analysis of safety status and the statistic of accidents of LPG storage tanks, with SAFETI in the DNV quantitative risk analysis software, the hazard of LPG and the putential hazard of fire and explosion in LPG storage tanks are analyzed, the types of fatal accidents such as jet fire, fireball, BLEVE and VCE,which are likely to happen are summed up,and the relevant models in SAFETI software are used for the quantitative assessment for fatal accident consequence in a LPG process storage area, the consequence models of accidents are established,the consequences of fatal accidents are forecasted and simulated exactly,the simulation results of hazard degree of accident including graphs and reports are acquired,which have significant engineering application value and will be good guidance to take effective measures for forecasting and preventing accidents.
