Pipeline and Liquefied Gases
Dakota Gas produces four types of gaseous products at the Synfuels Plant. Synthetic natural gas and carbon dioxide are derived from the coal gasification process. Liquid nitrogen, krypton and xenon gases are captured in the air separation process used at the facility.
These gas products move into various markets and have several different transportation methods.
Dakota Gas sends carbon dioxide through a 205-mile pipeline to Canada for use in enhanced oil recovery. Synthetic natural gas, in a cleaned form, is used for feedstock of other Dakota Gas products and also is sold on the publicly traded natural gas market.
Liquid nitrogen is used for various processes and applications such as refrigerant, prevention of igniting flammable gases and oil drilling activities. Krypton and xenon gases are used in windows, lighting and lasers.
