Within ASUs, multi-stage centrifugal compressors are vital since they efficiently compress and deliver air for subsequent separation processes. However, these compressors are susceptible to various failure modes, which can have a significant impact on the performance and safety of ASUs. To address this issue, Failure Modes and Effects Analysis (FMEA) is employed as a systematic approach for identifying, analyzing, and prioritizing potential failure modes in complex systems. This article provides an overview of the applications of FMEA in multi-stage centrifugal compressors within ASUs. It explores the challenges and benefits associated with FMEA, emphasizing its role in enhancing compressor reliability, reducing downtime, and fostering operational excellence.enArticle
