PC GasComp product lines are made up of specially formulated lubricants, which provide enhanced lubrication protection in high-temperature and high-pressure gas compressor operations.

PC GASCOMP SP SERIES

Petro-Canada Lubricants PC GasComp SP Compressor Fluids are specially formulated synthetic lubricants that provide enhanced lubrication protection in high temperature, high pressure and high specific gravity gas compressor applications. Unlike standard mineral oils, these polyalkylene glycol (PAG) synthetic lubricants offer much lower gas solubility which reduces viscosity loss from hydrocarbon dilution and greatly improves the operational viscosity and fluid film during operation. The high viscosity index, excellent lubricity and thermal stability are additional benefits in selecting PC GasComp SP 100, 150 and 220 instead of standard mineral oils for flooded screw and reciprocating compressors.

PC GasComp SP 100, 150 and 220 are recommended for:

• Compression of heavy hydrocarbon and water contaminated natural gas streams
• High pressure reciprocating gas compression
• Compression of Natural gas with CO₂
• Compression of Natural gas with H₂S
• Compression of acid gas 

Typical characteristics are shown below:

PC GASCOMP HT

Petro-Canada Lubricants PC GasComp HT Compressor fluids are designed for use in flooded screw, rotary vane and reciprocating compressors in natural gas production service and are intended for the compression of hydrocarbon gases at moderate discharge temperatures. These hydrotreated (HT) mineral oil based fluids include a specific additive formulary to help protect metal surfaces against corrosion from water and sour gas components providing excellent performance in the harshest natural gas application environments. The additive system is compatible with corrosive (H₂S & CO₂ ) hydrocarbon gas streams.

PC GasComp HT fluids are specifically recommended for:

• Compression of the hydrocarbon gases (methane and ethane) where the expected dilution is ≤10 wt% and rotary screw compressor discharge temperatures are moderate (<99 °C / 210 °F)
• High pressure reciprocating gas compression
• Compression of lower specific gravity sour or acidic gas streams
• Available in ISO 100 and ISO 150 viscosity grades

For more difficult gas streams, where heavy hydrocarbons are present, the PC GasComp SP series of PAG compressor fluids may be a better fit.

PC GasComp IPX 150

Petro-Canada Lubricants PC GasComp IPX 150 Compressor Fluid is a water insoluble polyalkylene glycol (PAG) fluid with a premium and modern additive package that provides excellent performance and operational efficacies specifically in flooded rotary screw and reciprocating compressors. The very high viscosity index, excellent lubricity and high thermal stability are additional benefits in selecting PC GasComp IPX 150 instead of standard mineral oils in Natural Gas service and for propane refrigeration.

PC GasComp IPX 150 is recommended for:

• Compression of propane in refrigeration service and compression of natural gas in lower density gas applications
• PC GasComp IPX 150 Compressor Fluids can also be used to lubricate reciprocating and rotary screw compressors in select applications. PC GasComp IPX 150 Compressor Fluid should not be mixed with mineral oil based lubricants
• Available in ISO 150 viscosity grade

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.
