  • Patent number: 8871008
    Abstract: Capturing a target gas includes contacting a gas mixture including a target species with an aqueous solution including a buffer species, and transferring some of the target species from the gas mixture to the aqueous solution. The target species forms a dissolved target species in the aqueous solution, and the aqueous solution is processed to yield a first aqueous stream and a second aqueous stream, where the equilibrium partial pressure of the target species over the second aqueous stream exceeds the equilibrium partial pressure of the target species over the first aqueous stream. At least some of the dissolved target species in the second aqueous stream is converted to the target species, and the target species is liberated from the second aqueous stream. The target species can be collected and/or compressed for subsequent processing or use.

  • Patent number: 8728210
    Abstract: An exhaust gas treatment apparatus comprises an ammonia absorption system and an ammonia conversion system. The ammonia absorption receives ammonia-containing tail gas generated by a semiconductor process, and removes dust from the tail gas, absorbs and decomposes ammonia gas from the tail gas, converts the ammonia gas into aqueous ammonia, and emits the tail gas without the dust and the ammonia to an external environment. The ammonia conversion system receives the ammonia solution from the ammonia absorption system, and converts it into gaseous ammonia, and then converts the gaseous ammonia to produce liquid ammonia by vaporization and cooling-pressurized liquefaction. After that, the liquid ammonia is purified by a purification system to formed hi-purity liquid ammonia.

    Abstract: Produced natural gas containing carbon dioxide is dehydrated and chilled to liquefy the carbon dioxide and then fractionated to produce a waste stream of liquid carbon dioxide and hydrogen sulfide. Natural gas liquids may be first separated and removed before fractionation. After fractionation, the waste stream is pressurized and transmitted to a remote injection well for injection either for disposal of the waste stream and preferably to urge hydrocarbons toward the producing well. A hydrocarbon stream proceeds from fractionation to a methanol absorber system which removes carbon dioxide gas. The hydrocarbon stream is thereafter separated into at least hydrocarbon gas, nitrogen and helium. Some of the nitrogen is reintroduced into a fractionation tower to enhance the recovery of hydrocarbons. A methanol recovery system is provided to recover and reuse the methanol. The hydrocarbons are sold as natural gas and the helium is recovered and sold. Excess nitrogen is vented.

  • Patent number: 8343256
    Abstract: An integrated contaminant separator and water-control loop (10) decontaminates a fuel reactant stream of a fuel cell (12). Water passes over surfaces of an ammonia dissolving means (61) within a separator scrubber (58) while the fuel reactant stream simultaneously passes over the surfaces to dissolve contaminants from the fuel reactant stream into the water. An accumulator (68) collects the separated contaminant stream, and ion exchange material (69) integrated within the accumulator removes contaminants from the stream. A water-control pump (84) directs flow of a de-contaminated water stream from the accumulator (68) through a water-control loop (78) having a heat exchanger (86) and back onto the scrubber (58) to flow over the packed bed (62). Separating contaminants from the fuel reactant stream and then isolating and concentrating the separated contaminants within the ion exchange material (69) minimizes cost and maintenance requirements.

  • Patent number: 8221528
    Abstract: Methods of using microchannel separation systems including absorbents to improve thermal efficiency and reduce parasitic power loss. Energy is typically added to desorb a solute and then energy or heat is removed to absorb a solute using a working solution. The working solution or absorbent may comprise an ionic liquid, or other fluids that demonstrate a difference in affinity between a solute and other gases in a solution.

  • Patent number: 8216346
    Abstract: The invention relates to a gas liquid contactor and effluent cleaning system and method and more particularly to an array of nozzles configured to produce uniformly spaced flat liquid jets with reduced linear stability. An embodiment of the invention is directed towards a stability unit used with nozzles of a gas liquid contactor and/or an enhancer for stable jet formation, and more particularly to reducing the stability of liquid jets formed from nozzles of the gas liquid contactor. Another aspect of the invention relates to operating the apparatus at a condition that reduces the stability of liquid jets, e.g., a droplet generator apparatus. Yet another aspect of the invention relates to operation of the apparatus with an aqueous slurry. Still another aspect of the invention is directed towards to an apparatus for substantially separating at least two fluids.

  • Publication number: 20120167766
    Abstract: A process and system for separating CO2 from a flue gas stream is disclosed. The process involves (a) contacting a flue gas stream containing water vapor and CO2 with an ionic absorbent under absorption conditions to absorb at least a portion of the CO2 from the flue gas stream and form a CO2-absorbent complex; wherein the ionic absorbent comprises a cation and an anion comprising an amine moiety; and (b) recovering a gaseous product having a reduced CO2 content.

  • Patent number: 8206490
    Abstract: A separator scrubber (58) and isolation loop (78) decontaminates a fuel reactant stream of a fuel cell (12). Water passes over surfaces of an ammonia dissolving means (61) within the scrubber (58) while the fuel reactant stream simultaneously passes over the surfaces to remove contaminants from the fuel reactant into the water. An accumulator (68) collects the separated contaminants and water, and an isolation loop pump (84) directs flow of the separated contaminant stream through the isolation loop (78). A heat exchanger (86) and an ion exchange bed (88) modify the heat of, and remove contaminants from, the separated contaminant stream, and the isolation loop (78) directs the decontaminated stream back onto the packed bed (62)-. Separating contaminants from the fuel reactant stream and then isolating and concentrating the separated contaminants within the ion exchange bed (88) minimizes cost and maintenance requirements.

  • Publication number: 20120134905
    Abstract: A method of use of an ionic liquid for sorption of a gas having an electric multipole moment is provided, wherein the ionic liquid comprises an anion and a non-aromatic cation. In particular, the electric multipole moment may be an electric dipole moment and/or an electric quadrupole moment. The sorption may be an adsorption or an absorption. The ionic liquid may be a pure ionic liquid, i.e. a liquid substantially only containing anions and cations, while not containing other components, e.g. water. Alternatively a solution containing the ionic liquid and a solvent or further compound, e.g. water, may be used.

  • Publication number: 20110232489
    Abstract: An amine solvent solution that is useful in absorbing acid gases from a liquid or gas feed stream may have an amine additive added thereto. Additionally or alternatively, the amine additive may be added to a liquid or gas feed stream. The addition of the amine additive decreases the presence of amine-derived contaminants and/or degradation of amine in the amine solvent solution. As such, the amine solvent solution is available for effective reuse in treating the liquid or gas feed stream and there may be a decrease in the corrosion within an amine treating system.
