ETA-FTA在化工装置安全评价中的应用

ETA-FTA in the application of chemical plant safety evaluation

将事件树分析法和故障树分析法综合应用于化工装置安全评价中,利用事件树去确定各个能导致后果的组成部分,从而把事件树转换成故障树,通过故障树进行事故原因查找分析,提出预防途径。ETA-FTA可以充分发挥两种方法的优势,从而使事故树的构建更能符合实际应用的要求。

The event tree analysis and the fault tree analysis are applied to the safety evaluation of chemical plant, using event tree to determine various part of leading to the consequence, which converts event tree into the fault tree. Through the fault tree to analyze and find the cause of the accident, and to put forward the prevention ways.ETA - FTA can give full play to the advantages of two methods, so that the construction of a fault tree is more in line with the requirements of practical application.
