Gas Pipelines

Did you know?

Gas needs to be compressed before it enters a pipeline. In 1984 the Synfuels Plant became part of $4 billion energy complex, which included the Antelope Valley Station and the Freedom Mine. The Freedom Mine is one of the nation's largest coal mines. 'Scrubbers' remove 97% of sulfur dioxide emissions from the flue gases in the Synfuels Plant's main stack.

The Great Plains Synfuels Plant has two pipelines: a synthetic natural gas pipeline moves gas from the plant to a hub on the Northern Border Pipeline. The other is a carbon dioxide pipeline operated by Souris Valley Pipeline, Ltd, a for-profit subsidiary of Dakota Gasification Company. This pipeline transports CO2 captured from plant processing and transports it to oil fields in Canada.

Syngas pipeline

Natural gas produced at the Synfuels Plant leaves the plant through a two-foot diameter pipeline that transports the gas 34 miles to a gas portal on the Northern Border Pipeline. The Northern Border Pipeline interconnects with a network of pipelines at Ventura, IA, where it is distributed throughout the eastern half of the United States.

Dakota Gas shares natural gas sales revenue with the U.S. Department of Energy through an agreement established in 1988 when Dakota Gas purchased the plant from the DOE. To date, Dakota Gas has given more than $379.8 million to the DOE.

CO2 pipeline

Dakota Gas captures and sells CO2 produced at the plant to two customers and transports it through a 205-mile pipeline to Saskatchewan, Canada, to be used for enhanced oil recovery (EOR) in the Weyburn and Midale fields.

The first CO2 was sent to Canada in October 2000. Today, Dakota Gas exports about 152 million cubic feet per day of CO2 to Canada – about two-thirds of the readily available CO2 when running at full rates.
