Root Cause Analysis Of A Long Term Reliability Problem With Reciprocating Compressors In H2 Service.
Abstract
Three large reciprocating compressors in H2 makeup service had
been a chronic reliability problem for 30 years. Unit revisions
greatly compounded this issue by eliminating builtin spare
capacity. A Root Cause Analysis Team was chartered to address the
reliability problem. Results achieved by this study essentially
eliminated production losses (which had peaked at over three
million dollars), improved valve life from three to six months to
two to four years, and decreased maintenance costs by factors of
three to five (several hundred thousand dollars per year).
This paper describes the overall root cause analysis study of
these compressors and presents the conclusions and recommendations.
It also details one phase of the analysis, evaluation of a
specific valve failure, in order to permit the reader to follow the
rigor utilized in the application of this type of analysis process.
