Compression Of Natural Gas

A key concern in hydrocarbon applications is hydrocarbon gas dilution of the lubricant. This dilution can reduce the lubricant’s working viscosity, which can be detrimental to equipment protection. That’s why we consider the compressor operating conditions, and gas analysis results to assess the potential dilution of the lubricant for each application before making a product recommendation. Please contact a Technical Services Advisor, who can recommend an appropriate fluid for your application.

Petro-Canada Lubricants NG CompOil AW 150 and 220 are mineral oil compressor fluids specially designed for use in reciprocating compressors. These products are for sweet, mostly light natural gas service operating at low pressure and employ a non-detergent formulation.

NG CompOil AW can be used in natural gas compressor skids where the engine and compressor lube oil feeds are from separate tanks. This low pour point formulation is suitable for remote locations where climate control is not practical.

NG CompOil AW compressor oils are recommended for use in:

Lubrication of cylinders / packings of reciprocating compressors in sweet, light natural gas service at low pressure. Both the ISO VG 150 as well as the ISO VG 220 product.
Crankcase of natural gas reciprocating compressors where an R&O type oil with anti-wear is recommended. ISO VG 150 product only.
