发布时间：2019-05-23 16:22
【摘要】：为简化危险与可操作性(HAZOP)分析,需要建立一种基于模糊综合评价的石化装置HAZOP分析节点重要度评价方法。首先构建包括9个一级评价因素、3个二级评价因素的因素集和各评价因素的评价等级标准,用层次分析法(AHP)确定各评价因素的相对权重;然后建立因素集与评价集之间的隶属度函数;最后根据二级模糊综合评价结果获得节点重要度等级。以某石化加氢裂化装置(28个节点)为分析实例,得到了装置中所有节点的重要度量化评价等级,非常重要的节点为6个、重要的节点为13个、一般节点为9个;结果符合装置安全管理的二八定律,验证了所建立的方法的有效性。
[Abstract]:In order to simplify the risk and operability (HAZOP) analysis, a method for evaluating the importance of the HAZOP analysis node of the petrochemical plant based on the fuzzy comprehensive evaluation needs to be established. The method includes the following steps: firstly, constructing a factor set including nine primary evaluation factors, three secondary evaluation factors and an evaluation grade standard of each evaluation factor, and determining the relative weight of each evaluation factor by using a hierarchical analysis method (AHP); and then establishing a membership function between the factor set and the evaluation set; And finally obtaining the node importance level according to the secondary fuzzy comprehensive evaluation result. Taking a petrochemical hydrocracking unit (28 nodes) as an analysis example, the important measurement and evaluation grade of all the nodes in the device is obtained, the most important nodes are 6, the important nodes are 13, the general node is 9, the result is in accordance with the two-eight law of the device safety management, The effectiveness of the established method is verified.
