Shell Gas Compressor Oil S4 PN 220
Advanced Synthetic Gas Compressor Oil
Shell Gas Compressor Oil S4 PN has been specially developed for cylinder lubrication of reciprocating compressors handling natural gas at high pressure. They are based on synthetic polyglycol base fluids and offer significant benefits over mineral oil-based products, especially in gas re-injection compressor applications.
Performance, Features & Benefits
- Extended maintenance intervals
- Outstanding wear protection
- Maintaining system efficiency
Main Applications
- Gas re-injection compressors
Recommended for cylinder lubrication of reciprocating compressors used for oilfield gas re-injection at pressure of up to 400 bar.
- LPG and LNG vehicle fueling
Suitable for use in compressors handling natural and petroleum gas for vehicle fueling applications.
- Other Applications
Shell Gas Compressor Oil S4 PN may also be used for compression of hydrocarbon process gases, carbon dioxide, hydrogen, helium and nitrogen.
- Change-over Procedure
Special changeover procedures are required when moving from mineral oil-based products to Shell Gas Compressor Oil S4 PN and vice versa, as the two types of fluids are immiscible. Additional advice on applications can be obtained from your Shell representative.
- Seal Compatibility
Shell Gas Compressor Oil S4 PN may be used with most common seal and packing materials compatible with polyglycols.
Leather seals are not recommended for use with polyglycol-based lubricants, as the natural fats are removed causing seal shrinkage and hardening.
