  • Patent number: 11920088
    Abstract: A method of continuously recovering hydrocarbons from carbon ores can include providing first and second vessels containing rubblized carbon ore. A cooling fuel gas can be introduced into the first vessel. The cooling fuel gas can include oxygen and a recycle gas from the second vessel, which includes hydrocarbons and oxidation products. The oxygen can be consumed through oxidation in an oxidation zone in the first vessel. The temperature of the oxidation zone can be controlled by limiting the oxygen concentration in the cooling fuel gas. This can produce a hot oxidation product gas that heats rubblized carbon ore in a pyrolysis zone downstream of the oxidation zone. Gaseous and vapor hydrocarbons can be produced in the pyrolysis zone. The vapor hydrocarbons can be condensed in a condensing zone downstream of the pyrolysis zone and then collected. The remaining gaseous hydrocarbons and oxidation products can be recycled as the recycle gas.

  • Patent number: 11851618
    Abstract: Recovering hydrocarbons from oil shale can include injecting a heated working fluid into a first vessel containing particulate oil shale in a pyrolysis mode. The heated working fluid can have a temperature above a production temperature to pyrolyze kerogen in a stationary bed of the oil shale at or above the production temperature. An effluent can concurrently flow out of the first vessel to be injected into a second vessel in preheating mode. The second vessel containing particulate oil shale has an average temperature below the production temperature so as to capture heat from the effluent sufficient to increase the average temperature of the particulate oil shale and to condense condensable hydrocarbon product while also removing entrained mineral fines mists of condensed hydrocarbons from the effluent. Liquid hydrocarbons can concurrently be collected from the first vessel and/or the second vessel.

  • Patent number: 10465124
    Abstract: Systems for extracting hydrocarbons from a crushed hydrocarbonaceous material can include a body of crushed hydrocarbonaceous material. A pipe can be oriented within the body of crushed hydrocarbonaceous material. The placement of the pipe can be such that the pipe is surrounded on top, bottom, and sides by the crushed hydrocarbonaceous material. The body of crushed hydrocarbonaceous material can be made up of portions having different void fractions. An arching control volume of crushed hydrocarbonaceous material can extend upward from the pipe to a vertical control distance. A support portion of crushed hydrocarbonaceous material can be oriented immediately adjacent sides of the arching control volume. The arching control volume can have a higher void fraction than the support portion. Internal friction between the arching control volume and the support portion can reduce stresses on the pipe as the hydrocarbonaceous material subsides.

  • Patent number: 10101098
    Abstract: A thermal insulation system can include a body of heated material at an elevated temperature. A layer of porous insulating material can be placed adjacent to and in fluid communication with the body of heated material. The insulating layer can contain distributed liquid water in an amount sufficient to cool the insulating layer through evaporative vapor flow toward the body of heated material. The amount of water can be sufficient to provide water vapor for inhibiting the diffusion and adsorption of hydrocarbons from the heated material. The insulating layer can include a continuous vapor phase. A heat sink material at a lower temperature can be placed adjacent to the insulating layer and opposite from the body of heated material.

  • Patent number: 9914879
    Abstract: Methods and systems of heating a body of crushed hydrocarbonaceous material to produce hydrocarbons therefrom can involve heating multiple zones of the body of material sequentially. An exemplary method can include forming a body of crushed hydrocarbonaceous material having a first zone and a second zone. The first zone can be heated in a first heating stage to form a dynamic high temperature production region in the first zone. A cooling fluid can then be injected into the first zone after the high temperature production region forms. The high temperature production region can move into the second zone in a second heating stage. Hydrocarbons can be collected from the body of crushed hydrocarbonaceous material during both the first and second heating stages.

  • Patent number: 9482467
    Abstract: A method for removal and condensation of vapors from within an enclosed space is disclosed. An enclosed space containing hydrocarbonaceous material is surrounded by an insulative permeable layer having a lowering temperature gradient between the inner surface and the outer surfaces. The insulative layer may also be covered by an impermeable layer. Heating the material in the enclosed space causes the formation of vapors at a positive pressure within the enclosed space. Vapors pass through the inner surface of the insulative permeable layer and contact the permeable materials and are condensed by the lowering temperature within the insulative layer. The condensate liquid passes downwardly through the insulative layer and is then collected.

  • Patent number: 9242190
    Abstract: A method of removing fines from a hydrocarbon-containing fluid can include preparing a bed media of particulate earthen material (12). The hydrocarbon-containing fluid having fines therein can be passed through the bed media (12) at a flow rate such that a portion of the fines are retained in the bed media (12) to form a filtered hydrocarbon-containing fluid. The flow rate is sufficient to maintain a wetting film of the hydrocarbon-containing fluid across at least a majority portion of the particulate earthen material which is contacted by the hydrocarbon-containing fluid. The filtered hydrocarbon-containing fluid can be recovered from the bed media (12) via a suitable outlet (16) having substantially reduced or eliminated fines content.

  • Patent number: 9079712
    Abstract: A method of maintaining structural integrity of a subsiding earthen fluid containment structure is disclosed and comprises forming a lined containment infrastructure (100) including a convex bulged crown portion (120), floor portion (110) and sidewall portions (115) which enclose a comminuted earthen material (126) within an enclosed volume (125) such that fluid flow from the lined containment compound is restricted. The bulged crown flattens, thickens and diminishes in surface area during subsidence of the comminuted earthen material as fluid is removed. The bulged crown is shaped to avoid tensile stresses which may otherwise result in breach or failure of lined containment during subsidence. Further, the lined containment structure can include an inner insulative layer and an outer impermeable seal layer having unique contributions as described in more detail herein.

  • Patent number: 8875371
    Abstract: An articulating conduit linkage system for maintaining a fluid connection between a fluid source and displaceable conduit that has been buried in a subsiding permeable body. A fluid source can supply a working fluid through a source outlet. A displaceable conduit can receive the working fluid through a conduit inlet, and be buried at a depth within a subsiding permeable body that is contained within a permeability control infrastructure. A plurality of articulating conduit segments can include, an outer conduit segment coupled to the source outlet, an inner conduit segment coupled to the conduit inlet, and at least one middle conduit segment coupled to the outer and inner segments.
