NGL and offgas fractionation is provided through interests in one straddle plants at Cochrane, as well as an integrated offgas business that includes the Redwater Olefinic Fractionator, Pioneer I and Pioneer II processing facilities located near Fort McMurray, Alberta, and the Boreal pipeline system that connects these facilities.
The facilities infrastructure segment generates adjusted EBITDA that is supported by fee-based and cost-of-service arrangements and sells commodity-based products to the marketing segment for fixed service fees.
The Cochrane straddle plant extracts and fractionates NGL into ethane and propane-plus and by production capacity, is the largest facility of its type in Canada. The plant has processing design capacity of 2.5 bcf/d of natural gas to recover approximately 100,000 b/d of NGL, of which 65,000 b/d are ethane and 35,000 b/d are propane-plus and processes a significant portion of available gas on the western leg of the TC Energy Alberta System.
Pioneer I and Pioneer II are two offgas plants located near Fort McMurray, Alberta and have the capacity to recover approximately 40,000 b/d of an ethane-plus mixture from upgrader offgas, a by-product of bitumen upgrading operations, helping to reduce GHG emissions. Once extracted, the liquid mix is shipped via pipeline to Inter Pipeline’s Redwater Olefinic Fractionator where it is fractionated into marketable products.
The Redwater Olefinic Fractionator is an ethane-plus fractionation plant near Redwater, Alberta. Ethane-plus produced from offgas processing is fractionated into an ethane-ethylene mixture as well as propane, polymer grade propylene, normal butane, alky feed and olefinic condensate. Once fractionated, the segregated products are sold and then transported to end-user markets by pipeline, truck or rail.
The Boreal pipeline system connects these facilities from Northern Alberta to the Alberta Industrial Heartland Alberta and has a current throughput capacity of 43,000 b/d of ethane-plus mixture.

Heartland Petrochemical Complex
Inter Pipeline is actively constructing a world-scale, integrated propane dehydrogenation (PDH) and polypropylene (PP) plant. The facilities, collectively referred to as the Heartland Petrochemical Complex, will be located near Inter Pipeline’s Redwater Olefinic Fractionator in Strathcona County, Alberta with an expected in-service date of early 2022.
