| 20080314246 | Removal of a target gas from a mixture of gases by swing adsorption with use of a turboexpander - The separation of a target gas selected from a high pressure gas mixture containing said target gas as well as a product gas using a swing adsorption process unit. A turboexpander is used upstream of the swing adsorber to reduce the pressure of the high pressure gas mixture. A compressor is optionally used downstream of the swing adsorber to increase the pressure of the target gas-containing stream for injecting into a subterranean formation. | 12-25-2008 |
| 20090205493 | Method of removing water from an inlet region of an oxygen generating system - A method of removing water from an inlet region of an oxygen generating system is disclosed herein. The method includes condensing, in an inlet region of the oxygen generating system, at least a portion of water vapor from a feed gas to water, and removing the water from the oxygen generating system prior to introducing the then-at least partially dehumidified feed gas to at least one sieve bed operatively disposed in the oxygen generating system. | 08-20-2009 |
| 20090205494 | Single manifold assembly for oxygen-generating systems - A device for generating an oxygen-enriched gas for a user includes a sieve module including a housing having at least one sieve bed operatively disposed therein. The sieve bed(s) include a nitrogen-adsorption material configured to adsorb at least a portion of nitrogen gas from a feed gas introduced thereto, wherein when the nitrogen gas is adsorbed, the oxygen-enriched gas is generated. The generated oxygen-enriched gas includes a substantially higher concentration of oxygen gas than that of the feed gas. The device further includes a single manifold assembly connected to an end of the sieve module. The single manifold assembly includes at least one supply valve and at least one user delivery valve connected thereto. The single manifold assembly further includes a flow path for each of the at least one supply valve and the at least one user delivery valve. | 08-20-2009 |

| 20110100215 | Method and Apparatus for the Catalytic Reduction of Flue Gas NOx - Described herein are a method and a reactor for reducing NOx contained in a gaseous emission stream. The method and the reactor both utilize an adsorption region in which NOx is adsorbed by either a catalyst material or a non-catalytic adsorbent material and a reduction region in which the adsorbed NOx is catalytically reduced by a hydrocarbon stream. Concentrations of components that inhibit catalytic NOx reduction, such as water vapour, oxygen, and sulphur dioxide, are lower in the reduction region than in the adsorption region. By adsorbing NOx in the adsorption region of the reactor and reducing NOx in the reduction region of the reactor, the reactor and method described herein allow for the efficient reduction of NOx from the emission stream even when the emission stream has a relatively high concentration of components that can inhibit efficient NOx reduction. | 05-05-2011 |
| 20110126708 | Gas Adsorbents Based on Microporous Coordination Polymers - The invention relates to gas adsorbents based on metal-organic microporous coordination polymers of the metallic bispyrmidinolate-type with a sodalite-type topology, having an adsorbent performance that is typical of crystalline microporous materials. The aforementioned materials also have a large accessible pore volume of between 25 and 45% of the total volume of the material with a monodispersion of pores having diameters of less than 1.3 nm. In addition, the materials have a high capacity for adsorption of small gases, such as carbon monoxide, carbon dioxide, hydrogen, nitrogen, methane, acetylene, etc., which is reversible such that, once said gases have been stored, they can be desorbed. Moreover, owing to the crystalline nature thereof, said materials are suitable for applications associated with the selective adsorption of small molecules such as for the safe storage of combustible gases and for the purification of gases with the elimination of trace impurities using dehydrated metal-organic porous compounds. | 06-02-2011 |
| 20110232486 | Adsorbent Media with Li Exchanged Zeolite - An adsorbent media composition has a finished media lithium-exchanged zeolite X (LiX) with a finished Li content in a range from 96% to 83%, based on the total cation equivalents in the LiX. The adsorbent media composition is obtained from a slurry comprising water, a LiX precursor having a pre-media production Li content that is greater than the finished media LiX Li content, and another media component material, such as fibers. The water used to produced the media has a specific conductance in a range from 2.2 μSiemens/cm to 150 μSiemens/cm. The finished media LiX has a monovalent cation (Na, K, Rb, Cs and combinations thereof) in a range from 0.05% to 3%, based on the total equivalents of exchangeable cations in the finished media LiX. | 09-29-2011 |
| 20140137737 | DUAL OXYGEN CONCENTRATOR SYSTEMS AND METHODS - Described herein are various embodiments of an oxygen concentrator system that includes a home oxygen concentrator system couplable to a portable oxygen concentrator system. | 05-22-2014 |
| 20160184760 | ADSORPTION AIR SEPARATION UNIT WITH PURGE RECOVERY TANK - A single bed reversing blower vacuum swing adsorption air separation unit includes a purge recovery tank. This purge recovery tank is joined to an O | 06-30-2016 |
