  • STEAM GENERATOR AND CARBON DIOXIDE CAPTURE
    Publication number: 20140360726
    Abstract: Methods and systems generate steam for injection into a formation in order to facilitate oil recovery and also capture carbon dioxide in a recovery unit that receives flue gas exhaust from such steam generation. The methods and systems integrate various process streams from and to the carbon dioxide recovery unit. Such integration provides resulting benefits associated with efficiency and/or carbon dioxide avoidance.

  • THROTTLING BOILER FOR FOULING MITIGATION
    Publication number: 20140246196
    Abstract: Methods and systems generate steam for thermal oil recovery, such as a steam assisted gravity drainage (SAGD) operation. Feedwater is first pressurized to a pressure above that desired for steam injection in the SAGD operation before being heated to avoid at least some nucleate boiling. After being throttled, the local boiling regime is beyond the nucleate boiling regime due to the local pressure drop and the enhanced mixing caused by the throttling process. Two-phase liquid may continue through the boiler generating higher quality steam.

  • OIL UPGRADING WITHIN COMBUSTION EXHAUST
    Publication number: 20140197072
    Abstract: Methods and systems relate to upgrading hydrocarbons, such as bitumen, by contacting the bitumen with flue gas of oxy-combustion. Quenching a mixture formed of the bitumen and the flue gas controls conversion of the bitumen. Limited size and amount of equipment needed enables employing such upgrading at production fields to facilitate making the bitumen transportable by pipeline without relying on diluents.

  • INDIRECT STEAM GENERATION SYSTEM AND PROCESS
    Publication number: 20130014709
    Abstract: Embodiments relate to production of hydrocarbons from an underground formation. More specifically, embodiments relate to a system and method for generating steam for heavy hydrocarbon production process. The indirect steam generation system uses moving hot solids (e.g. sand, metal spheres, etc) to produce steam from non-treated (dirty) boiler feed water. The solids are then transported to another vessel (e.g.combustor) where they are reheated and cleaned of contaminants before being recycled back to the boiler to produce more steam.
