  • Patent number: 7833326
    Abstract: Pressure swing adsorption (PSA) assemblies with purge control systems, and hydrogen-generation assemblies and/or fuel cell systems containing the same. The PSA assemblies are operated according to a PSA cycle to produce a product hydrogen stream and a byproduct stream from a mixed gas stream. The byproduct stream may be delivered as a fuel stream to a heating assembly, which may heat the hydrogen-producing region that produces the mixed gas stream. The PSA assemblies may be adapted to regulate the flow of purge gas utilized therein, such as according to a predetermined, non-constant profile. In some embodiments, the flow of purge gas is regulated to maintain the flow rate and/or fuel value of the byproduct stream at or within a determined range of a threshold value, and/or to regulate the flow of purge gas to limit the concentration of carbon monoxide in a heated exhaust stream produced from the byproduct stream.

  • Publication number: 20040187683
    Abstract: A gas recovery system for improving the efficiency of abatement and/or implementing reclamation and reuse of unused feed materials in effluent of a semiconductor manufacturing facility, especially in instances in which substantial portions of feed material are unused. The effluent is treated to reversibly capture the unused feed material, e.g., at a capture locus such as a physical adsorbent, cold finger, cryotrap, heat exchanger/condenser, membrane separation unit, filter, etc., and the captured unused feed material then is released from the capture locus and processed for such abatement and/or reclamation and reuse.

  • Patent number: 6783738
    Abstract: A circular rotating body having a plurality of fan-shaped blocks is disposed inside a casing and driven to rotate. A gas absorption/releasing material in the blocks absorbs/releases a specific gas component from a gas mixture depending on temperature. The rotating body has a hollow static central portion which is divided to form two temperature adjusting fluid paths through which temperature adjusting fluids having different temperatures pass. First and second independent gas flow paths are defined by the casing. A gas mixture containing the gaseous component flows along the first gas flow path through blocks which are heated to a first temperature at which absorption takes place. The blocks are then rotated to a position wherein they are heated to a higher second temperature and release the gaseous component which is exhausted via the second gas flow path. Blocks sequentially enter positions which separate the two different zones.

  • Patent number: 6755892
    Abstract: A system and method for controlling carbon dioxide (CO2) emissions emanating from a gas source includes a CO2 sorbent bed containing a regenerable sorbent. Exhaust gases flow through the CO2 sorbent bed before being released into the atmosphere. The CO2 sorbent bed traps CO2 contained within the exhaust gas to control the amount of CO2 finally exhausted to the atmosphere. At least two CO2 sorbent beds are used such that while one is absorbing CO2 from the gas stream another is being regenerated. The CO2 sorbent bed is regenerated to release the trapped CO2 for disposal or use in other processes. The CO2 sorbent beds are cycled between absorbing CO2 and regenerating to optimize absorption of CO2.

  • Patent number: 6706097
    Abstract: A molecular sieve apparatus and magnetic/adsorbent material composition facilitate molecular adsorption and separation using a magnetic field to hold, move, cool, and/or heat an adsorbent 1 that is bonded to magnetic materials 3 that are moveable by a magnetic field. An adsorbent 1 is bonded to a soft magnetic material 3 with a binder 2 into a powder composite material adsorbent attractable by a magnetic field (magnetoadsorbent 4). Magnetoadsorbent 4 functions to adsorb and desorb working substances, causing a molecular separation; thereby increasing the efficiency of the adsorption cycle by moving the adsorbent 1 to a location that optimally processes the adsorbent 1. Magnetic field manipulation of adsorbents 1 enables delivery of molecules to locations within systems. Magnetoadsorbents 4 of the present invention further increase the efficiency of the adsorption cycle by combining materials with functions including: catalyst, buoyancy, suspension, magnetic heating, and sinking in liquid.

  • Patent number: 6689196
    Abstract: A fuel adsorption layer formed in a canister is partitioned into an upper adsorption layer and a lower adsorption layer by a partition plate in which a heater is embedded. The relation between a heating value of the heater and thickness X of the upper and lower adsorption layers is set so that the temperature of a part closest to the heater heating face of the fuel adsorption layer is lower than a fire point of the fuel, and the temperature of a part farthest from the heater heating face is higher than the boiling point of the fuel. With the configuration, by heating the fuel adsorption layer by the heater, the desorption performance of activated carbon is improved, and almost all of the fuel vapors adsorbed can be desorbed.

  • Publication number: 20030209142
    Abstract: In a method for removing carbon dioxide from the exhaust gas from a gas turbine plant (11), which exhaust gas is subjected to a downstream heat recovery process (12, 33), preferably in the heat recovery steam generator (33) of a water/steam cycle (12), a simplification of the plant engineering is achieved by the fact that the carbon dioxide is removed from the exhaust gas (39) between the gas turbine plant (11) and the heat recovery process (12, 33), and that a rotating, regenerative absorber/desorber (22) is used to remove the carbon dioxide, the absorber side of which absorber/desorber is connected into the exhaust gas stream (39) and the desorber side of which absorber/desorber is connected into a carbon dioxide cycle (38).

  • Publication number: 20030167925
    Abstract: In a heat storage system for a vehicle, when a temperature of cooling water from a vehicle engine is high, adsorbents are heated by the cooling water, so that moisture is desorbed from the adsorbents in order to store heat. When the temperature of cooling water is low, the moisture is adsorbed in the adsorbents to heat the cooling water, while refrigerant in a vapor compression refrigerator is cooled by evaporating water. Thus, adsorption heat is generated from the adsorbents, and the cooling water is heated by using the adsorption heat. Accordingly, warm-up operation of the vehicle engine is facilitated, while motive power consumed by the vapor compression refrigerator can be reduced.

  • Patent number: 6615612
    Abstract: A method and apparatus is taught for preheating of glass batch materials by direct contact with glass furnace exhaust gases. Furnace gases 15 flow through a batch hopper 1 in horizontal tunnels formed by open bottom tubes 6, with a free surface of batch forming the bottom portion of the tunnel. The tubes are electrically grounded and a high voltage discharge electrode 18 is located axially in each tunnel. The corona discharge from the electrode acts to retain batch and prevent it's entrainment into the flowing gases. Particulate matter from the gases is simultaneously precipitated onto the batch surface. Acidic gas components such as SO2, HCl, and HF are chemically reacted with batch constituents, thereby removing them from the gas stream. Heat is transferred from the gases to the batch by direct contact. Cooled gases 16 exit the hopper, cleaned of pollutants to levels in compliance with strict environmental regulations.
