摘要
以某液化石油气储罐为例,采用初步风险分析方法,对储罐事故隐患进行识别,确定储罐事故类型,利用事故树计算得到各事故类型的结果重要度,发现火球事故和喷射火事故对周围环境具有极大威胁。通过ALOHA软件与PHAST软件对液化石油气泄漏过程进行仿真模拟研究对比,得到场景条件下的火球事故和喷射火事故的受威胁区域,并提供直观的图像和文字描述。模拟结果可为液化石油气泄漏事故的预防和控制提供有效信息,为炼油厂储罐的安全管理提供科学指导。
Taking a LPG storage tank in a refinery as an example,the preliminary risk analysis method was adopted to identify the storage tank’s hidden dangers of accidents,determine accidents types and employ the accident tree to calculate the results of each type of accidents.The results show that,both LPG fireball accidents and jet fire accidents pose great threats to the surrounding environment.In addition,ALOHA software and PHAST software were used to simulate LPG leakage process of the refinery,and the threatened area of fireball explosion and fire accident under this scenario was obtained.The simulation results provide effective information for the prevention and control of LPG leakage accidents and scientific guidance for the safety management of refinery storage tanks.
