摘要
为了解决传统故障树分析方法中,依赖参与人员经验导致评价结果相对主观的问题,利用多级流模型（MFM）模拟实际流程,改进化工过程定量风险评价（QRA）初始事件发生频率的计算方法。首先,应用MFM对化工过程建模,并根据MFMSuite软件推理出的故障逻辑原因树建立故障树,按照事件发生的逻辑顺序找出故障原因;然后,计算顶上事件的发生频率,即为该过程初始事件的发生频率;最后,以氰化氢生产流程中粗产品的冷却过程作为应用实例。研究表明：针对热交换工艺过程,MFM计算方法运用原因树推演故障树,与传统方法相比,结果更为客观。
Traditional fault tree analysis relies on the experience of the analysis,which makes the assessment results relatively subjective. In order to solve this problem,MFM is used to simulate the actual flow to improve the calculation method of initiating event frequency in chemical process QRA. Firstly,the chemical process is modeled by MFM platform,and then a fault tree is established according to the causal paths reasoning through the MFMSuite software. Finally,the frequency of the top event is calculated according to the logical sequence of the events and the frequency of the initiating event is determined. The method is applied to a heat exchange step in the production process of hydrogen cyanide. The research shows that this method can use the causal paths to deduce the fault tree for the heat exchange process,and that compared with the traditional methods,the result obtained by using the method developed by theauthors is more objective.
