承压设备动态风险关键影响因素研究

Research on Key Factors Influencing Dynamic Risk of Pressure Equipment

随着炼化装置朝着大型化方向发展,设备检验、管理和维护工作标准越来越高,炼化装置长周期安全运行保障的需求也越来越强烈。为此,企业应针对炼化装置开展动态风险评估。本文基于设备风险计算原理,通过数据源分析和参数分类,研究了承压设备动态风险关键影响因素,构建了动态风险计算参数表,并开发了计算程序进行验证。本文研究结果对于预知性检验机制的建立,以及装置长周期运行保障具有重要的理论意义。

The standards of inspection,management and maintenance on equipment become higher than before with the development of large-scale refining and chemical plants.Meanwhile,the demand for the safety security for long-term operation of refining and chemical equipment is becoming stronger and stronger.So,the dynamic risk assessment in operation is demanded in the plant management.The key influencing factors were studied based on the principle of equipment risk calculation.Through data source analysis and parameter classification,the parameter table of dynamic risk calculation of pressure equipment was established and a calculation program for verification was developed.It is helpful for the establishment of predictive inspection mechanism.It is also of great theoretical significance to guarantee the long-term operation of the plant.
