Dakota Gasification Company
Dakota Gasification Company's carbon dioxide is produced from washing the syngas in our Rectisol unit. It has a purity of about 95%, with about 1% of the remaining 5% being hydrogen sulfide. Pure carbon dioxide is colorless and odorless, however, because of the impurities in our product there is a distinctive odor. Dakota Gas and its Canadian subsidiary, Souris Valley Pipeline Limited (SVPL), operate a 205-mile carbon dioxide (CO2) pipeline to transport CO2 from the plant to Saskatchewan, Canada. Dakota Gas has three electric-driven, integral geared type centrifugal compressors. Each compressor has eight stages. Each compressor has a capacity of 55 mmscf/d and is driven by a 19,500 horsepower fixed-speed motor.
• Dakota Gas production capacity is in excess of 215 million standard cubic feet per day.
• Used in tertiary or enhanced oil recovery (EOR) techniques.
• Can be used for fracking, a technique of pumping pressurized CO2 into wells to shatter the rock and push out more oil and gas.
