CNG加气站事故树分析

Fault Tree Analysis of CNG Stations

为了找出引起CNG站最危险的事故——爆炸的原因,建立了以"爆炸事件"为顶端事件的CNG站事故树,并对其进行定性分析,计算了各基本事件的重要度;找出了CNG加气站的主要安全隐患,提出了改进措施,为CNG站的安全可靠性分析提供了一种新的科学方法,同时提高了CNG站运行的可靠性。

For finding out the causes of most dangerous hazard - explosion hazard in CNG stations, this paper presented a qualitative analysis method based on fault tree with explosion as root .The important degree of basic event was calculated, the main security risk was identified, improvement measures were put forward . This method provides a new scientific method for safety of CNG stations and reliability analyses and also improves reliability of CNG stations.
