  • Patent number: 9821265
    Abstract: An air separation unit includes an air inlet with a reversible blower downstream therefrom and an adsorption bed filled with adsorption media downstream of the reversible blower. The adsorption bed contains an adsorption media which preferentially adsorbs nitrogen over oxygen. An oxygen and argon output is located downstream of the absorption bed. At least a portion of the mixed gas of oxygen and argon is routed to a modular argon separator which separates out at least a portion of the argon to provide high purity oxygen to a high purity oxygen outlet. The argon separator can be configured as a molecular sieve filter to separate the argon from the oxygen or the argon separator can be in the form of a gas cooler and condenser which condenses liquid oxygen for storage and discharge as substantially pure oxygen.

  • Patent number: 9676629
    Abstract: The present invention generally relates to a method to enhance heat transfer in the temperature swing adsorption process (TSA) and to an intensified TSA process for gas/liquid purification or bulk separation. Helium is designed as the heat carrier media to directly bring heat/cool to the adsorbent bed during the TSA cycling process. With helium's superior heat conductivity, the time consuming regeneration steps (warming, regeneration and precooling) of TSA process can be significantly reduced and allowing for the TSA process to be intensified.

    Abstract: Methods of absorbing oxygen are disclosed with the use of compositions useful as oxygen absorbers. The compositions are generally salts of unsaturated fatty acids that have one or more carbon to carbon double and or triple bonds. The compositions may be prepared by reacting an unsaturated fatty acid with a hydroxide resulting in a salt of the unsaturated fatty acid. Water soluble compositions are dissolved in aqueous solutions for the purpose of absorbing oxygen from the aqueous solutions and or their containers. Water insoluble compositions are protected from moisture due to their water repellent character and this characteristic is used advantageously in order to absorb oxygen from containers that may contain moisture where it is desired that the compositions remain relatively unaffected by moisture, intact and remain where they are placed.

  • Patent number: 8147591
    Abstract: Systems and methods for producing an ozone destructor are disclosed herein. Generally, these systems and methods include an ozone destructor that has a housing defining an air passage duct. In some cases, this air passage duct includes a first chamber and a second chamber that are arranged so that air is able to flow into the first chamber, through the second chamber, and out of the destructor. In some cases, an air drying mechanism is disposed in the first and/or the second chamber. Additionally, in some cases, the ozone destructor further includes multiple mechanisms that reduce ozone to oxygen. In light of these features, the ozone destructor is capable of incrementally drying and reducing air and ozone, respectively, as they pass through the first chamber and the second chamber.

  • Publication number: 20120055334
    Abstract: A method for removing negatively-charged gas molecules includes the steps of: adsorbing negatively-charged gas molecules by a substrate carrying a positively-charged substance or a positively-charged substance and a negatively-charged substance on the surface of the substrate or in a surface layer of the substrate; and desorbing the aforementioned negatively-charged gas molecules adsorbed on the aforementioned substrate, from the substrate using a fluid. According to the present invention, negatively-charged gas molecules are removed or detoxified by adsorbing the same by a substrate carrying a positively-charged substance, or a positively-charged substance and a negatively-charged substance, on the surface of the substrate. Thereby, it is possible to provide a simple process by which negatively-charged gas molecules are able to be effectively and economically removed or detoxified.

  • Patent number: 8012241
    Abstract: The present invention provides a method and an apparatus for condensing ozone arranged so as to efficiently take out the ozone gas of a predetermined concentration, although its construction is simple. The method for condensing the ozone gas comprises acting ozone-oxygen mixture gas on an adsorbing cylinder which is filled in its interior area with an adsorbent so as to selectively adsorb the ozone gas to an adsorbent and desorbing the selectively adsorbed ozone gas so as to condense and purify the ozone gas. The method further includes acting the ozone-oxygen mixture gas on the adsorbent in non-cooled state to selectively adsorb the ozone gas to the adsorbent and vacuuming the adsorbing cylinder on performing desorption-operation of the ozone gas to desorb the ozone gas from the adsorbent.
