基于危险与可操作性(HAZOP)技术的CNG加气站工艺危害分析

Process Hazards Analysis of CNG Filling Station Based on Hazard and Operability Analysis( HAZOP0[l1])

为进一步提高CNG加气站系统的安全设计及运行水平,在对危险与可操作性(HAZOP)技术工作流程进行简要介绍的基础上,结合某CNG加气站的具体实例,对其进行了工艺危害分析,辨识出了工艺系统存在的问题,提出了装置工艺安全水平,也促使操作人员对工艺过程及设备有更加深入的了解,为设备设施的维护及装置的安全管理提供了指导。

In order to further improve safety design and operation level of CNG filling station system,basing on the brief introduction of the process of the hazard and operability analysis( HAZOP0),combining with the specific example of a CNG filling station,the process hazard analysis on CNG filling station system was carried out,the relevant improvement measures and suggestions including the addition of safety facilities,adjusting the process,were proposed,by which the process of CNG filling station was optimized. From the results of the analysis and recommendations,HAZOP technology can be used in process hazards analysis of CNG filling station system to identify the problems existing in the process system of CNG filling station,to promote improving the device process safety level,also can make the operator have a more in-depth understanding of the process and equipment,providing guidance for the safety management maintenance and installation of facilities.
