  • Publication number: 20140284066
    Abstract: The present invention is an in-situ apparatus for generating carbon dioxide gas at an oil site for use in enhanced oil recovery (EOR). The apparatus includes a steam generator adapted to boil and superheat water to generate a source of superheated steam, as well as a source of essentially pure oxygen. The apparatus also includes a steam reformer adapted to react a carbonaceous material with the superheated steam and the pure oxygen, in an absence of air, to generate a driver gas comprising primarily carbon dioxide gas and hydrogen gas. A separator is adapted to separate at least a portion of the carbon dioxide gas from the rest of the driver gas to generate a carbon dioxide-rich driver gas and a hydrogen-rich fuel gas. A compressor is used for compressing the carbon dioxide-rich driver gas for use in enhanced oil recovery, and the compressed carbon dioxide-rich driver gas, with substantially no oxygen, is injected to a predetermined depth in order to enhance oil recovery at the oil site.

  • Publication number: 20140065026
    Abstract: Methods and apparatus for removing oil or natural gas from the ground. In one example, the method may include reforming a fuel source by reaction with water to generate driver gas, and injecting the driver gas into the oil well. The reforming operation may include causing the combustion of a combustible material with ambient oxygen for the release of energy; and heating a reforming reaction fuel and water sources, with the energy released from the combustion of the combustible material, to a temperature above that required for the reforming reaction wherein the fuel and water sources are reformed into driver gas. In one example, the amount of the combustible material combusted is sufficient to result in the release of enough energy to heat an amount of the reforming reaction fuel and water sources to the temperature above that required for the reforming reaction to proceed. The driver gas may be used to help extract oil from the ground and especially oil from depleted oil wells.

  • Patent number: 8047007
    Abstract: Disclosed herein is a method for generating “clean” electricity from carbonaceous material, and producing high-pressure CO2 which can be easily sequestered or utilized for a beneficial purpose, such as fuel production. This method utilizes a reformation process that reforms carbonaceous fuel with superheated steam into a high-pressure gaseous mixture that is rich in carbon dioxide and hydrogen gas. This high-pressure gas exchanges excess heat with the incoming steam from a boiler. Once cooled, the high-pressure gas goes through a CO2 separator, after which the CO2-rich gas is sequestered underground or beneficially re-used. The remaining hydrogen-rich gas is used to generate power in a power generation subsystem, such as a gas turbine or a fuel cell. Therefore, carbon-free power is produced from coal, biomass, natural gas, or another carbon-based feedstock.

  • Patent number: 7937948
    Abstract: A reformation power plant generates clean electricity from carbonaceous material and high pressure CO2 which can be easily sequestered or utilized for a beneficial purpose, such as fuel production. The reformation power plant design utilizes a reformation process that reforms carbonaceous fuel with super-heated steam into a high-pressure gaseous mixture that is rich in carbon dioxide and hydrogen gas. This high-pressure gas exchanges excess heat with the incoming steam from a boiler and continues onward to a condenser. Once cooled, the high-pressure gas goes through a methanol separator, after which the CO2-rich gas is sequestered underground or beneficially re-used. The remaining hydrogen-rich gas is combusted through a gas turbine. The gas turbine provides power to a generator and also regenerative heat for the boiler. Finally, the generator converts mechanical energy into electricity, which is transferred to the electric grid.

    Abstract: The present invention is a natural gas steam reforming method for generating an output gas mixture of carbon dioxide and hydrogen, including the following steps. (1) Combusting a portion of the natural gas with an oxidizing agent to generate heat, superheated steam, and a gas mixture of carbon dioxide, carbon monoxide, and hydrogen. (2) Steam reforming the gas mixture with additional superheated steam under steam-rich conditions to transform a remaining portion of the natural gas into carbon dioxide, carbon monoxide, and hydrogen. (3) Water-gas-shifting any residual carbon monoxide into additional carbon dioxide and additional hydrogen by utilizing a water-gas-shift catalyst downstream of the steam reforming step, thereby producing an effluent gas mixture that is predominantly carbon dioxide and hydrogen.

  • Patent number: 7918906
    Abstract: The present invention is natural gas steam reforming apparatus for generating an output gas mixture of carbon dioxide and hydrogen. The apparatus is made from two enclosures. A first enclosure contains a source of water, superheated steam, and channels, located within a lower portion of the first enclosure, which contain a water-gas-shift catalyst for converting CO into CO2 and H2. The heat from hot gas flowing through the channels is released into the first enclosure to boil the water to generate the superheated steam. A second enclosure, contained within an upper portion of the first enclosure, includes a steam inlet for receiving the superheated steam from the first enclosure; a combustion chamber; and a reformation chamber. The combustion chamber is used for combusting a portion of the natural gas to generate additional steam, heat, and a hot gas mixture of CO2, CO, and H2.

  • Patent number: 7753972
    Abstract: The Portable Renewable Energy System for Enhanced Oil Recovery (“PRESEOR”) is a truck mobile system that reforms biomass into CO2 and hydrogen, following which the gases are separated, with the CO2 sequestered underground for enhanced oil recovery (EOR) and the hydrogen used to generate several megawatts of carbon-free electricity. In contrast to large central power plants that are generally not well-located to support EOR, the small PRESEOR can go directly to the oilfields where it is needed, and do so in a timely manner. The PRESEOR sequesters more biomass-derived carbon than is released by the burning of the oil it yields, thereby producing not only carbon-free electricity but carbon-free oil. Using PRESEOR, over 80 billion barrels of U.S. oil would be made recoverable, without the need to drill new wells in pristine areas.

  • Patent number: 7654330
    Abstract: Apparatus, methods, and systems for extracting oil or natural gas from a well using a portable coal reformer. In one example, the method may include reforming coal by reaction with water to generate driver gas (comprising carbon dioxide and hydrogen gas), and injecting the driver gas into the well. The driver gas reduces the viscosity and pressurizes the oil to help extract the oil from the oil well. The coal reforming operation may include combusting coal or other combustible material with ambient oxygen to release energy, and heating coal and water with the energy released to a temperature above that required for the coal reforming reaction to proceed, thereby reforming coal and water into driver gas. The driver gas may be purified by filtering out particles and sulfur before injecting into the well. A portion of the hydrogen gas may be separated from the driver gas and used to generate electrical power.

  • Patent number: 7624801
    Abstract: A control system and control method for controlling a modular apparatus for extracting petroleum and/or generating electricity based on subsurface data as well as market prices of electricity and/or petroleum. One or more probes measure subsurface total pressure, partial pressure of carbon dioxide, partial pressure of hydrogen, oil flow rate, gas flow rate, underground temperature, and/or viscosity of the oil. The control system/method controls the apparatus based on the subsurface parameters by controlling an injection module and/or a gas separator module to increase or decrease output of driver gas. The control system/method may also control the injection module and/or the gas separator module to increase (or decrease) output of driver gas when the market price of electricity decreases (or increases) and/or petroleum increases (or decreases).
