HAZOP分析在氢气提纯工艺装置设计阶段的应用

Application of HAZOP Analysis in Design Stage of Hydrogen Purification Process Unit

HAZOP(危险与可操作性分析)是定性分析危害的一种风险分析方法。石油化工装置由于其自身物料的特性,危险系数极高,对其进行HAZOP分析非常有必要。通过对装置进行HAZOP分析,识别装置存在的潜在危险,结合风险评价与HAZOP,进而制定一系列的措施来提高装置运行的安全性和可靠性,以保证生产投用中的生命和财产安全。以某石化公司的氢气提纯装置为例,进行了HAZOP分析,优化了工艺流程,为装置的长期可靠稳定运行提供保障。结果显示,HAZOP分析方法是辨识风险的一种可靠有效的方法,HAZOP分析能够在石油化工装置的安全管理方面发挥巨大的作用,能够为安全管理者提供依据,进而降低安全等级。

HAZOP(Hazard and Operability analysis)is a risk analysis method for qualitative analysis of hazards.Hazop analysis is necessary for petrochemical plant because of its high hazard coefficient due to its material characteristics.Through the HAZOP analysis of the device,identifying the potential hazards of the device,and combining the risk assessment and HAZOP(hazard and operability analysis),a series of measures can be developed to improve the safety and reliability of the device operation,so as to ensure the safety of life and property in production and use.Taking the hydrogen purification unit of a petrochemical company as an example,HAZOP analysis was carried out to optimize the process flow,so as to ensure the long-term reliable and stable operation of the unit.The results show that HAZOP analysis can play a huge role in the safety management of petrochemical plants,and can provide basis for safety managers.
