Application of the reliability-centered maintenance techniques for dynamic equipment in the petrochemical ammonia-related systems

The reliability-centered maintenance (RCM) analysis method and the RCM implementation process for dynamic equipment in petrochemical ammonia-related systems were introduced. The operation situation, key roles, and potential risks were clarified through data analysis and system screening in ammonia dynamic equipment, and FMEA was used to analyze the failure mode. Then the risk of each failure mode was managed hierarchically, a suitable risk assessment standard and risk matrix were developed for the enterprise, and a suitable maintenance strategy was formulated for the risk level of each failure mode.
