Reducing wear to improve the lifetime of key operating components
Mangalore Refinery and Petrochemical Limited (MRPL) and Howden have been working in association since 1993; during which time Howden engineers have regularly visited the refinery to ensure that the C25-2 reciprocating compressor was operating in the most effective way possible.
During one such visit in 2011, it became apparent that the compressor was suffering from excessive wear to the piston and rider rings, as well as to the liner of the accompanying 2nd stage cylinder.
This represented a massive problem to MRPL, resulting in decreased operational efficiency and on-going replacements to worn out components; costing time and money.
In response to this challenge, Howden initiated a performance upgrade study, using actual process data, to firstly understand the correlation between the relatively high temperatures experienced and the excessive wear of the identified parts, and then to recommend a solution which would significantly improve the meantime between maintenance (MTBM) in a clear and costed manner.
