Hydrocarbon gas liquids facts

What are hydrocarbon gas liquids?

Hydrocarbon gas liquids (HGLs) include natural gas liquids (NGLs) (propane, butane, and ethane) and olefins produced by natural gas processing plants and upstream processing or by crude oil refineries.

These gases can be easily liquefied, and therefore are commonly referred to as “liquids”.

Supply and demand

In 2019, Canadian production of hydrocarbon gas liquids was 684.8 thousand barrels per day, which is composed by:

  • Propane: 294.5 Mb/d
  • Butane: 195.6 Mb/d, and
  • Ethane: 241.8 Mb/d

The total amount of hydrocarbon gas liquids exported in 2019 was 243.8 thousand barrels per day. Canada also imported 48.6 thousand barrels per day.

Supply and demand excludes condensates and pentanes plus, which are included as part of crude oil, and includes refinery-produced LPGs.

Gas processing plant production of hydrocarbon gas liquids in 2019 was 682 thousand barrels per day. Alberta has the largest share of production at 85%, British Columbia follows with 13%, and Saskatchewan with 2%.

Natural gas liquids energy use

Natural gas liquids (NGLs) have a wide variety of industrial and commercial uses. For example, ethane, propane and butane are used as feedstock for the creation of value added petrochemicals (e.g. polypropylene which is used in a wide variety of consumer products, such as plastics). NGLs can also be used for residential and commercial heating, cooking fuel, blending with vehicle fuel, diluent for heavy oil and bitumen, or for the production of fertilizers.

In 2017, the total use of energy by natural gas liquids was 142.7 PJ.

Sector Energy use* (PJ) % of the total
Residential 17.6 12.3%
Commercial 40.4 28.3%
Industrial 62.0 43.5%
Transportation 12.2 8.6%
Agriculture 10.5 7.3%
Total 142.7 100%
