NGL ProcessingPrint Page
Inter Pipeline’s NGL processing business consists of 100 percent ownership interests in the Cochrane and Empress II plants and a 50 percent ownership interest in the Empress V plant (collectively the “Straddle Plants”). The Empress II and V plants are located on the eastern leg and the Cochrane plant is located on the western leg of the TransCanada Alberta System near the natural gas export points from the province of Alberta. These plants process pipeline quality natural gas to remove natural gas liquids (NGL) comprised of ethane, propane, butane and pentanes-plus. The NGL stream is then partially fractionated to produce a specification ethane product and propane plus, a mixture of propane, butane and pentanes-plus.
In addition, Inter Pipeline has 100 percent ownership interests in two offgas extraction facilities located near Fort McMurray, Alberta, an olefinic fractionator near Redwater, Alberta and the Boreal pipeline system that connects these facilities (collectively the “offgas business”). The two extraction facilities have the capacity to recover approximately 40,000 b/d of NGL and high-value olefins from upgrader offgas, a by-product of bitumen upgrading operations. Once extracted, the liquids mix is shipped via pipeline to Redwater where it is fractionated into marketable products and sold across North America.
In 2015 the straddle plants processed an average of 2.7 bcf/d of natural gas producing an average of 102,000 b/d of NGL. In September 2016, Inter Pipeline acquired the offgas business adding ~40,000 b/d of NGL and olefin production capacity bringing the combined business total production capacity to over 240,000 b/d. NGL and olefins are generally used directly as an energy product and as a feedstock for the petrochemical and crude oil refining industries.
