  • Patent number: 11866667
    Abstract: An energy efficient process for NGL recovery and production of compressed natural gas (CNG) in which natural gas is fed to a first gas separation membrane-based separation stage where it is separated into a permeate and a retentate. The high C3+ concentration first stage permeate is chilled and separated to provide liquid phase NGL and a gaseous phase. The first stage retentate is separated at a second gas membrane-based separation stage to produce a retentate meeting pipeline specifications for CNG (including hydrocarbon dewpoint) and a permeate that is recycled to the first stage. The gaseous phase, constituting a low BTU fuel, may be used in on-site power generation equipment and/or in internal combustion engines. The second stage permeate (and optionally the third stage retentate) is (are) recycled back to the first stage to enhance the production of NGL and CNG.

  • Patent number: 11654393
    Abstract: Solid sorbents, and especially zeolites, are attractive candidates for CO2 direct air capture (DAC) and point source capture applications because of their potential for high selectivity, fast kinetics, and low energy CO2 capture cycles. A common issue with solid sorbents, including zeolites, is their low thermal conductivity, which makes them difficult to heat for regeneration without using complex and expensive heat transfer systems. This invention utilizes a modified TVSA process which utilizes the product CO2 gas itself as the heating medium for the adsorbent bed, alone or in conjunction with internal or external heaters. The use of CO2 as a heating medium allows efficient heating of the sorbent bed and enables high purity CO2 product.

    Abstract: The cryogenic trapping system traps organic arsenicals within a centrally-positioned cryotrap body and allows inorganic arsenical to flow through the cryotrap body. As a hydride gas is directed into the central cryotrap body, the gas is cooled by a pair of Peltier units that sandwich the cryotrap body so that the cold side of each of the Peltier units abuts the cryotrap body. The hot side of each Peltier unit abuts a heat exchanger—which cools the Peltier unit. In the preferred embodiment, organic arsenicals are trapped in a sorbent bed within the cryotrap body.

  • Patent number: 8974575
    Abstract: Disclosed is a method for enriching combustible gas, which suppresses the deterioration and pulverization of an adsorbent without extending a period for pressure equalization. The pressure equalization is effected by opening a pressure equalization passage opening/closing valve incorporated in a pressure equalization passage, after completion of adsorption in a first adsorption tower and after completion of desorption in a second adsorption tower connected to the first adsorption tower via the pressure equalization passage.

  • Patent number: 8940077
    Abstract: A method for indirectly monitoring and controlling an electrically resistive adsorption system. Adsorption of a predetermined adsorbate is conducted while indirectly monitoring electrical resistance of a unified adsorbent element. Breakthrough is predicted based upon the indirectly monitored electrical resistance and a previously measured mass loading relationship between the resistance of the unified adsorbent element and the loading of the unified resistance element with the predetermined adsorbate. Adsorption, regeneration and cooling cycles are controlled by a controller without any direct measurement of temperature or resistance of the element and characterizations of mass loading and temperature. Systems of the invention can have no sensors that contact the element, are in an adsorption vessel, and/or are downstream adsorption vessel.

  • Patent number: 8931262
    Abstract: A method for controlling the effective heat transfer from a storage unit (1). During gas release from storage material (3) in the storage unit the storage material is heated by a heater (2). During re-saturation of the storage material (3) with gas the heater is off. Controlling of the effective heat transfer from the storage unit (1) is performed, during gas release, by ceasing convection of a convection gas and, during re-saturation, by performing or enabling convection of a convection gas to cool the storage unit (1).

  • Patent number: 8784535
    Abstract: The present invention relates to a pressure-temperature swing adsorption process wherein gaseous components that have been adsorbed can be recovered from the adsorbent bed at elevated pressures. In particular, the present invention relates to a pressure-temperature swing adsorption process for the separation of C2+ hydrocarbons (hydrocarbons with at least 2 carbon atoms) from natural gas streams to obtain a high purity methane product stream. In more preferred embodiments of the present processes, the processes may be used to obtain multiple, high purity hydrocarbon product streams from natural gas stream feeds resulting in a chromatographic-like fractionation with recovery of high purity individual gaseous component streams.

  • Patent number: 8778061
    Abstract: The reaction exhaust gas from which chlorosilanes and hydrogen chloride have been removed in a hydrogen chloride absorption unit (30) is introduced to an adsorption unit (50) to recover a purified hydrogen (S105). Activated carbon is packed in the adsorption unit (50), the gas, which is mainly composed of hydrogen, is passed through the activated carbon-packed layer during which unseparated chlorosilanes, hydrogen chloride, nitrogen, carbon monoxide, methane, and monosilane contained in the gas are adsorbed on the activated carbon and removed from the gas, and thereby the purified hydrogen is obtained. Nitrogen, carbon monoxide, methane and monosilane are a compressed gas in the state of adsorption, whereas hydrogen chloride and chlorosilanes are a liquid in the state of adsorption, and require a vaporization heat during desorption. Using these properties, the separation of hydrogen chloride and chlorosilanes from other impurity components is possible merely by separating the pathways for the desorbed gas.

    Abstract: A process for removing heavy hydrocarbons from a natural gas stream comprises passing the natural gas stream thought a TSA adsorbent unit to adsorb heavy hydrocarbons, regenerating the TSA adsorbent by heating to form a contaminant-containing gas phase, cooling the contaminated gas phase to separate water and heavy hydrocarbon liquids to form a third gas phase and directing the third gas phase to a PSA unit to adsorb heavy hydrocarbons from the third gas phase. The product from the PSA unit can be sent to pipeline or recycled to the TSA unit for further hydrocarbon removal and recovery.

  • Patent number: 8753427
    Abstract: In various implementations, various feed gas streams which include hydrogen and carbon monoxide may be processed for conversion to product streams. For example, the feed gas stream may be processed using the Fischer-Tropsch process or a methanol synthesis process. Unconverted hydrogen and carbon monoxide can be recycled at high recovery and/or inert components removed to prevent build-up in the recycle system by using an arrangement of pressure swing adsorption systems designed to recover impure product gas streams.
