Definitions

  • Embodiments of the invention relate to methods and systems for processing carbon dioxide in flue gas from oxy-fuel combustion utilizing steam assisted oil recovery.
  • Oxy-fuel combustion refers to burning of fuel in oxygen (e.g., 95% pure oxygen) instead of air to reduce amount of nitrogen in resulting flue gas.
  • the flue gas from the oxy-fuel combustion thus contains carbon dioxide and water vapor, which can be removed if condensed through cooling.
  • the oxy-fuel combustion facilitates carbon dioxide capture since the flue gas is almost pure carbon dioxide with trace amounts of impurities, such as oxygen (e.g., about 0.1-2 volume percent) remaining due to equilibrium constraints as well as local mixing conditions during combustion.
  • Alternate approaches utilize the flue gas from the oxy-fuel combustion. For example, injecting the flue gas into reservoirs of natural gas helps displace the natural gas. However, gas phase interactions of the flue gas in the reservoirs and the interactions not occurring at where the reservoir is being heated limits any possible oxygen removal from the carbon dioxide.
  • a method includes forming a mixture of flue gas from oxy- fuel combustion and steam generated prior to being mixed with the flue gas.
  • the flue gas contains carbon dioxide with an initial concentration of oxygen that is at least 0.1 volume percent.
  • injecting the mixture into a subterranean formation heats oil in the formation and reacts with the oil at least some of the oxygen that is from the flue gas and is dissolved in liquid condensate of the steam.
  • the method further includes recovering fluids including the oil that is heated and carbon dioxide from the flue gas and separating the fluids recovered to isolate from a liquid phase the carbon dioxide containing less than the initial concentration of oxygen for transporting the carbon dioxide to a sequestration site.
  • a method includes producing flue gas from oxy- fuel combustion, generating steam without contact of the steam with the flue gas, and introducing the steam into the flue gas to form a mixture.
  • the flue gas contains carbon dioxide with quantities of oxygen greater than a transport specification.
  • the method includes injecting the mixture into a subterranean formation for heating oil in the formation, recovering fluids including the oil that is heated and the carbon dioxide from the flue gas, and separating the fluids into liquids and vapors.
  • the vapors formed of the carbon dioxide meet the transport specification due to removal of at least some of the oxygen by oxidation of the oil upon the oxygen being dissolved in condensate of the steam for liquid phase reactions at temperatures elevated by the steam.
  • the method further includes transporting to a sequestration site the carbon dioxide obtained by the separating.
  • a system includes a supply of flue gas from an oxy-fuel combustion chamber, a source of steam generated without contact of the steam with the flue gas, and an injection well disposed in a subterranean formation containing oil.
  • the injection well couples in fluid communication with the supply of the flue gas and the source of the steam.
  • a vapor-liquid separator of the system receives produced fluids heated by the steam.
  • the vapor- liquid separator also outputs carbon dioxide that is in the produced fluids from the flue gas and is processed by liquid phase reactions between the oil heated by the steam and at least some oxygen that is from the flue gas and is dissolved in condensate of the steam.
  • the oxy-fuel combustion produces the flue gas 107 containing carbon dioxide with at least 0.1 volume percent oxygen as a result of burning fuel in oxygen, such as at least about 95% by volume pure oxygen separated from air.
  • the carbon dioxide may make up by volume at least about 85%, at least about 90%, or at least about 95% of the flue gas 107.
  • Sources for the fuel include coal, petroleum coke, asphaltenes, methane, natural gas and hydrogen. To limit resulting flame temperatures to levels common during conventional combustion and within thermal thresholds, some cooled combustion gases may circulate back and be injected into a combustion chamber used for the oxy-fuel combustion.
  • the mixture makes the petroleum products mobile enough to enable or facilitate recovery with, for example, the production well 102.
  • the injection well 101 includes a horizontal borehole portion that is disposed above (e.g., 0 to 6 meters above) and parallel to a horizontal borehole portion of the production well 102. While shown in an exemplary steam assisted gravity drainage (SAGD) well pair orientation, some embodiments utilize other configurations of the injection well 101 and the production well 102, which may be combined with the injection well 101 or arranged crosswise relative to the injection well 101, for example.
  • SAGD steam assisted gravity drainage
  • a vapor chamber develops in the formation 103 and grows as the products are recovered. Walls of the vapor chamber form an interface with the products where the steam 105 condenses transferring heat to the products that then drain to the production well 102. Since the flue gas 107 containing the oxygen is injected into the vapor chamber during development of the chamber, the oxygen contacts this condensate of the steam 105 and is dissolved in the condensate enabling both the condensate to carry oxygen into the products and liquid phase reaction of the oxygen with the products. For some embodiments, effective removal of the oxygen from the carbon dioxide in the flue gas 107 relies on the reactions being in liquid phase compared to inefficient gas contact of the oxygen with the products.
  • this oxidation of the products further depends on temperature at which the oxygen contacts the products since oxygen uptake by the products increases with rising temperature.
  • the reactions for some embodiments occur at temperatures that are elevated by the steam 105 and may be above about 100° C, above about 150° C or above about 200° C.
  • Injection of the flue gas 107 through a separate well and outside of the vapor chamber formed by the steam 105 heating the products tends to keep the oxygen in gas phase and insulated from thermal heating by the steam 105 due to physical separation of the oxygen from the condensate.
  • injection of the flue gas 107 after stopping injection of the steam 105 prevents ability of the oxygen to be dissolved in the condensate and carried into the products at as high a temperature as possible. While helpful for processing the carbon dioxide in the flue gas 107, the oxidation of the products lacks influence on recovery due to only trace amounts of the oxygen in the flue gas 107.
  • transport of the carbon dioxide includes compressing the vapor phase 112 that is then passed through a pipeline.
  • the pipeline may carry the carbon dioxide to a sequestration facility such as a geologic reservoir distant from the formation 103 in which the products are recovered.
  • injection of the flue gas 107 from the oxy-fuel combustion into a depleted hydrocarbon reservoir passes the flue gas 107 into contact with unrecovered petroleum products that react with the oxygen from the flue gas 107.
