摘　　要：文章以某厂区中的液氨储罐为研究目标,取不同的风速,运用挪威船级社的PHAST7.01软件对液氨储罐泄漏进行事故模拟,得出相应的图表和报告,并对导致的火灾、蒸气云爆炸事故进行风险分析。结果表明,在同一大气稳定度下,风速的增加可使液氨泄漏产生的喷射火、闪火和蒸气云爆炸后果减小。This paper takes the liquid ammonia storage tank in a factory as the research goal,and selects different wind speeds,using the PHAST7.01 software of Norwegian Classification Society to simulatethe leakage accident of liquid ammonia storage tank.Meanwhile,the risk of jet fire and steam cloud explosion accident is analyzed.The results show that the jet fire,flicker and explosion caused by liquid ammonia leakage can be reduced with the increase of wind speed under the same atmospheric stability.

关 键 词：PHAST软件 液氨储罐 风速
