HAZOP-LOPA分析在金属钝化剂反应釜的应用

Application of HAZOP-LOPA Analysis in Metal Passivator Reactor

金属钝化剂的生产过程需要使用氧化剂H2O2,反应风险较大,一旦反应失控,则会出现超温超压的可能。文章将金属钝化剂反应釜及其连接管道划分为一个节点,通过HAZOP-LOPA分析方法,辩识到该节点不可接受的风险共计4个,其中3个在现有独立保护层的作用下,剩余风险可接受。针对放空阀未开启的操作失误可能引起反应釜超压运行的情况,建议在反应釜上设置爆破片,风险等级可降低至中风险区域,为隐患排查和安全生产提供了参考和保障。

The production process of a certain type of metal passivator requires the use of oxidizing agent H2O2,which has a greater risk of reaction.Once the reaction is out of control,over-temperature and over-pressure may occur.The article divides the metal passivator reactor and its connecting pipeline into one node.Through the HAZOP-LOPA analysis method,it is identified that there are 4 unacceptable risks for this node.For 3 of them,the remaining risks are acceptable under the existing independent protective layer.In view of operating errors(the vent valve is not opened)that may cause overpressure operation of the reactor,it is recommended to install a bursting disk on the reactor,and the risk level can be reduced to D2(medium risk,allowable risk area).It provides reference and guarantee for hidden danger investigation and safe production.
