摘　　要：采用基于风险的检测技术,对某石化公司的加氢裂化装置的承压设备和管道进行风险评估,并结合中国石化行业法规和现状,制定出科学合理的检测计划。详细阐述了RB I技术的实施过程,从数据收集、介质危害分析、损伤机理分析、腐蚀回路和物流回路划分,计算设备项失效概率以及失效后果,从而确定了风险结果,然后制定优化的检测计划,提出降低风险的措施,最后对生产和管理提出建议。采用这种方法,不仅对高风险的设备提供了更加有效的检测方法,而且使检测得到合理科学分配,降低了检验成本。其更深远的意义在于通过对装置工艺条件的整理和分析,提高了整个装置的管理水平。Adopting the risk-based inspection(RBI) technology to perform a risk evaluation of a certain petro-chemical corporation's pressure equipment of the hydrocracker as well as the pipeline,and considering the industrial regulations and present situation in China's petro-chemical industry,a scientific inspection plan was made.The paper expounds in detail the process of applying the RBI technology and determines the risk results by calculating the equipment's failure probability and effect through analysis of data collection,medium hazard,damage mechanism,corrosion loop and logistics loop.Then,it makes the optimized inspection plan,puts forward the measure to decrease risk and finally offers suggestions on production and management.Adoption of this method provides the more effective inspection method for high-risk equipments and guarantees a scientific distribution of inspection,thus decreasing inspection costs.Its more profound significance lies in improvement of the management level of the whole equipment through arrangement and analysis of the equipment and technical conditions.
