大型LNG储罐泄漏事故后果分析

Consequence Analysis of Leakage Accident of Large LNG Storage Tank

天然气是一种优质、高效的清洁能源,广泛地应用于各个行业中。我国部分沿海城市已建造了大型LNG接收站,运用PHAST软件,输入发生事故时的真实场景,可对LNG储罐泄漏事故后果进行计算和分析,从而确定泄漏、扩散、燃烧和爆炸等危险区域范围。分析结果能帮助接收站直观了解发生事故后的危险程度,进而能够针对性地采取相应的安全措施。

Natural gas is a kind of high quality,high efficiency,clean energy,Which is widely used in various industries.In order to use natural gas Conveniently,some coastal cities in our country have built many large LNG storage tanks.Liquefied natural gas is the flammable and explosive dangerous goods,so once a tank leaks,it may cause very serious consequences.The PHAST software,once being input the real scene at the time of an accident,can calculate and analyze the diffusion,the flash fire,the fire disaster,or the explosion immediately,quickly determining the leakage,diffusion,combustion and explosion hazard area,and measuring the personnel death radius,serious injury radius and minor injury radius caused by the fire thermal radiation and explosion pressure.Analysis of the accident can help receiving stations intuitively understand the degree of danger after the accident so as to take corresponding measures.
