System For Separating Carbon Dioxide And Hydrocarbon Gas From A Produced Gas Combined With Nitrogen
US Patent:
8118915, Feb 21, 2012
Filed:
Aug 22, 2008
Appl. No.:
12/197032
Inventors:
Donald Leo Stinson - Laramie WY, US
International Classification:
B01D 53/12
US Classification:
95183, 95193, 95209, 95229, 95236
Abstract:
Produced natural gas containing carbon dioxide is dehydrated and chilled to liquefy the carbon dioxide and then fractionated to produce a waste stream of liquid carbon dioxide and hydrogen sulfide. Natural gas liquids may be first separated and removed before fractionation. After fractionation, the waste stream is pressurized and transmitted to a remote injection well for injection either for disposal of the waste stream and preferably to urge hydrocarbons toward the producing well. A hydrocarbon stream proceeds from fractionation to a methanol absorber system which removes carbon dioxide gas. The hydrocarbon stream is thereafter separated into at least hydrocarbon gas, nitrogen and helium. Some of the nitrogen is reintroduced into a fractionation tower to enhance the recovery of hydrocarbons. A methanol recovery system is provided to recover and reuse the methanol.
