摘　　要：作为清洁能源的甲烷,具有很大的发展潜力。为保证甲烷化装置系统的安全稳定运行,基于危险和可操作性(HAZOP)分析与模糊扩展蝴蝶结(FEBT)模型对托普索甲烷化工艺装置系统进行了风险分析。先使用HAZOP分析和风险矩阵对该甲烷化装置系统进行了风险辨识和风险等级划分,再使用FEBT模型对该甲烷化装置系统中管道或容器内发生火灾爆炸事故的基础事件和安全屏障事件发生的可能性进行了计算。结果表明:该甲烷化装置系统中管道或容器发生火灾爆炸事故的风险管控排序最为优先;人为误操作和机械工艺方面的法兰密封失效是直接导致事故场景发生的主要促成事件。该研究结果为该甲烷化装置系统在日常安全管理中指明了关键事件,并验证了HAZOP分析和风险矩阵以及FEBT模型在化工装置系统风险分析中的有效性。As a clean energy source,methane has great potential for development.In order to ensure the safe and stable operation of the methanation unit system,the risk analysis of Topso methanation unit ststem was conducted.Firstly,H AZOP analysis and risk matrix were employed to carry out the risk identification and the risk level classification of the methanation unit system.Then the fuzzy extended bow tie(FEBT)model was used to calculate the possibility of basic events and safety barrier events of pipeline or container fire and explosion accidents in the methanation unit system.The results are as follows:the risk value of fire and explosion of pipelines or containers is the highest priority;mannual misoperation and flange sealing failure in mechanical process are direct and primary cause of accidents.This research identifies the key e-vents for the daily safety management of the methanation unit system,and verifies the effectiveness of HAZOP analysis,risk matrix and FEBT model in risk analysis.
