chevron Cetus® DE 100
solves compressor valve
deposits build up

Chevron field engineers advice to Formosa tanker FPMC C LORD

to switch compressor lubricant to Cetus® DE 100
cures exhaust carbon deposit build up.

Situation

Vessel FPMC C LORD faced issues with carbon deposits on valves when using mineral compressor oils in air compressors. Mineral lubrication is mainly used for internal lubrication of moving components but under high-temperature and high-pressure applications the lubricant can be oxidized particularly when residual oil remains in the exhaust valve and pipe. This can lead to thermal decomposition, dehydrogenation aggregation in combination with impurities and dust drawn into the intake combining and deposited on the hot valve surface eventually forming carbon deposits.

 

Results

Following the change to Cetus® DE 100, Formosa reported significantly improved compressor performance. The crew aboard the chemical tanker reported significant improvements in valve cleanliness and compressor performance after switching from a mineral air compressor oil.
Chevron Cetus DE 100 is a fully formulated, high-quality synthetic compressor lubricant based on diester technology to protect reciprocating air compressors against carbon deposit build up and wear. The vessel operates suction gas compressors, which operate at high temperatures. The technical superintendent noted the following benefits after the change to Cetus DE 100:

 

⇒ Significant improvement in compressor performance compared to the previously used mineral

air compressor oil because there was a reduction in carbon deposits.

⇒ Clean in/outlet valves with very low carbon deposits, meaning longer running periods between maintenance.

⇒ Reduced deposits in discharge lines and improved safety in compress air systems.

⇒ Reduced wear of piston rings, cylinders and bearings.

⇒ Improved equipment reliability and reduction in unscheduled downtime.

 

 

 

 

Conclusion

The significant performance and maintenance improvement has lead to Formosa deciding to switch another eleven vessels to Cetus DE 100 over the following months including vessels using different air compressors, such as YANMAR, J.P. SAUER & SOHN all changing from mineral air compressor oil to synthetic Cetus DE 100.
