Abstract
A process for producing steam for use in a hydrocarbon recovery process includes introducing feed water into a steam generator to produce the steam and a blowdown stream, contacting the blowdown stream from the steam generator with a flue gas including carbon dioxide from the steam generator to absorb at least a portion of the carbon dioxide from the flue gas, and directing the blowdown stream including the portion of the carbon dioxide absorbed from the flue gas, into a disposal well.
Claims24
A process for producing steam for use in a hydrocarbon recovery process, the process comprising:
- introducing feed water into a steam generator to produce the steam and a blowdown stream;
- contacting the blowdown stream from the steam generator with a flue gas including carbon dioxide from the steam generator to absorb at least a portion of the carbon dioxide from the flue gas;
- and
- directing the blowdown stream including the portion of the carbon dioxide absorbed from the flue gas, into a disposal well.
A method treating flue gas from a steam generator utilized for producing steam for use in a hydrocarbon recovery process, the method comprising:
- producing steam and blowdown stream utilizing the steam generator;
- and
- contacting the blowdown stream from the steam generator with the flue gas from the steam generator to absorb at least a portion of carbon dioxide from the flue gas and provide a treated flue gas having reduced carbon dioxide content.
A system for producing steam for use in a hydrocarbon recovery process, the system, comprising:
- a feed water source;
- a combustible gas source;
- a steam generator coupled to the feed water source and to the combustible gas source to produce steam from feed water;
- and
- a contactor coupled to the steam generator to receive blowdown stream produced from the steam generator and coupled to the steam generator to receive flue gas generated therefrom, for contacting the blowdown stream with the flue gas to absorb at least a portion of carbon dioxide in the flue gas.
