| 摘 要： | 天然气在现代生活中应用越来越广泛,为了在紧急情况下能够正常供应液化天然气,我国的部分城市已建造了大型液化天然气储罐。由于液化天然气易燃易爆性,模拟其发生火灾爆炸的可能性具有重大的借鉴作用。本文运用挪威DNV公司研制的PHAST软件输入发生事故时的真实场景,包括设备类型,物质种类,存储参数,泄漏方式,周围环境(大气温度、湿度、稳定度、风速)等设置,模拟液化天然气储罐发生不同的泄漏事故,绘出能够真实描述事故危害的计算机图表、报告等评价结果。运用PHAST软件模拟得出不同的孔径,不同的风速,不同大气稳定度的条件下,泄漏扩散浓度定量分析的结果,通过下风向距离,云团宽度来描写火灾爆炸区域,为提高我国液化天然气的安全管理水平,降低事故风险提供依据。

| Abstract: | Natural gas is widely used in daily life now,in order to supply liquefied natural gas(LNG) even in the emergency situation, large LNG tanks have been built in some cities of china.As LNG is easily to get flamed and exploded,simulating the possibility of accident plays a significant role.PHAST was used in the paper,which is developed by DNV in Norway,to analyze the leak accident of LNG storage quantificationally,which caused in different diameter of holes and environment.According to the result which describ... |
