In addition to a high level of wear metal contamination the refinery’s centrifugal compressors lubricant was showing MPC values >40 which put it in a critical level for varnish potential.
RIG’s reliability division, PetrolinkUSA, was contracted to provide services on the compressor lube oil system during the turnaround. The services performed included:
- Varnish mitigation flush with Step One Cleaner
- Purge / particle contamination flush with virgin oil
- Side stream filtration of final fill oil
Our team successfully removed varnish from a refinery’s centrifugal compressor lube oil system, achieving changing the MPC from >40 to 1. High velocity flushing combined with side streaming filtration an chemical cleaning.
