Manufacturer's description
High-performance synthetic gas compressor oil. Shell Gas Compressor S4 PV has been specially developed as a versatile cylinder lubricant for reciprocating compressors handling a range of hydrocarbons and other gases. It is based on polyalkylene glycol fluids and is fully approved by the leading gas compressor manufacturers.
Applications
- Reciprocating gas compressorsLubrication and crankcase systems of enclosed compressor designs handling hydrocarbons and other gases, where the crankcase and bearings operate in a gas atmosphere.
- Versatile gas compression applicationsShell Gas Compressor S4 PV is suitable for compressors handling the following gases: methane; butylene; ethane; butadiene; ethylene; vinyl chloride monomer (VCM); propane; propylene; ammonia; inert gases (dry); butane.
Performance & benefits
- Extended maintenance intervalsShell Gas Compressor S4 PV has reduced solubility for gaseous hydrocarbons, ensuring reduced viscosity loss compared with mineral oil based products, improving piston ring and packing lubrication and helping to extend service intervals, reducing maintenance and downtime costs.
- Outstanding wear protectionLow solubility for gaseous hydrocarbons, combined with low viscosity loss, results in a strong lubricant film being maintained on the cylinder wall, piston rings and packing components, giving low cylinder wear and corrosion.
- Maintaining system efficiencyLower cylinder feed rates are possible compared with conventional oils, as a result of the high levels of wear protection and lubrication, with improved reliability and reduced oil carry-over into the compressed gas.
- Shell Gas Compressor S4 PV is approved by the following manufacturers of cargo gas and general service compressors
- Burckhardt Compression AG: approved for use in K-type gas compressors for general LPG/LNG service and for ammonia, vinyl chloride monomer, butadiene, etc. Meets the Burckhardt Lubricating Oil Specification (VSB) 1001301
- Linde AG: approved for general gas compression service, including ammonia, vinyl chloride monomer and butadiene
- GreenField AG (Atlas Copco): approved for use in the trunk piston of gas compressors handling hydrocarbons, helium, argon, hydrogen, nitrogen and carbon dioxide gases
