DETAILS:
One (1) hour presentation, including up to 15 min. Q&A
DESCRIPTION:
This presentation explores a detailed case study of a coupling failure and significant damage experienced by a centrifugal gas compressor within a nitric acid compressor train, triggered by a sudden acceleration following a control system modification in 2023. The incident occurred on June 24, 2023, and involved a comprehensive analysis of the factors leading to the coupling's failure.
The study provides an in-depth examination of the calculations and findings related to the failure, emphasizing the impact of the abrupt acceleration during the start-up phase. The analysis identifies critical factors contributing to the failure, including the absence of an acceleration protector and deviations from the recommended start-up procedures.
The presentation offers conclusions and actionable recommendations aimed at preventing similar incidents in the future. It underscores the importance of implementing an acceleration protection mechanism and adhering strictly to specified start-up sequences. By sharing these insights, the presentation seeks to enhance understanding of coupling failure mechanisms and promote best practices in the maintenance and operation of industrial machinery. This case study serves as a valuable resource for improving operational reliability and safety in similar industrial settings.
