【摘要】 采用事故树法分析了储罐的腐蚀行为,根据储罐内腐蚀和外腐蚀两种主要类型,建立了储罐腐蚀的事故树.通过对事故树的定性分析,可得到储罐腐蚀的30个最小割集.根据分析结果,采取相应防护措施如:抗静电涂料防腐、涂料与阴极保护相结合的保护技术、热喷铝技术以及添加缓蚀剂等,以提高储罐运行的安全性.更多还原

【Abstract】 Corrosion failure of tanks was analyzed in this paper using Fault Tree Analysis.Fault Tree was set up based on two corrosion types:internal corrosion and exterior corrosion.Then 30 minimal cut sets of tank corrosion were gained by qualitative analysis of the fault tree.Correspondingly protective measures including use of antistatic coating,cathodic protection combined with coating,thermal spraying aluminum technology,and adding corrosion inhibitor are adopted to improve the security of tanks according to analysis results.更多还原
