摘要
结合危险与可操作分析(HAZOP)评估及保护层分析(LOPA)对化工罐区的风险识别,需要进行紧急切断阀的改造应用.为此,先进行罐区风险分析,对常用切断阀进行功能及原理讨论,为工程改造提供基础.其次,结合工程案例提出具体的改造方案,同时完善切断阀的设计要求及应用原则.最后,在LNG系统中落实紧急切断阀的应用实践,能提高罐区介质应用的安全性.
Abstract
Combining Hazard and Operability Analysis(HAZOP)assessment and Layer of Protection Analysis(LOPA)for risk identification in chemical tank areas,it is necessary to carry out the transformation and application of emergency shut-off valves.To this end,a risk analysis of the tank area is conducted first,and the functions and principles of commonly used shut-off valves are discussed,providing a foundation for engineering renovation.Secondly,specific renovation plans will be proposed based on engineering cases,while improving the design requirements and application principles of the shut-off valve.Finally,implementing emergency shut-off valves in LNG systems can improve the application of media in tank areas the safety.
