20100095841 | VSA gas concentrator using a reversing blower - The concentrator separates one gas (i.e. oxygen) from a gas mixture (i.e. air) through the process of vacuum swing adsorption (VSA). An adsorber material is located within an adsorber bed. The adsorber bed has an inlet and an outlet. A valve is located downstream of the outlet. A pump, such as a blower, is provided upstream of the adsorber bed to drive a mixed gas into the adsorber bed. The adsorber material selectively adsorbs an undesirable gas (i.e. nitrogen) leaving a desirable gas (i.e. oxygen) from the mixture to pass through the outlet and through the valve. The pump is reversible. When the adsorber material becomes saturated, the pump is reversed and a vacuum is drawn on the adsorber bed. The valve is closed while the pump is operating in this reverse direction. After the adsorber material has desorbed the undesirable gas, the pump again reverses and the cycle is repeated. | 04-22-2010 |

20120325086 | SYSTEM AND METHOD OF OPERATION FOR CONTROLLED ATMOSPHERE STORAGE - A nitrogen-flush scrubber system for a controlled atmosphere room in which the amount of nitrogen required to flush the regenerated scrubber beds is significantly reduced. The present invention provides a dual-bed scrubber system in which low oxygen air salvaged from the active scrubber bed is used to flush high oxygen air from the regenerated scrubber bed prior to nitrogen flush. The scrubber system may include two scrubber beds that are used alternately to scrub air from the CA room. One scrubber bed is used as an active scrubber bed to remove carbon dioxide from the air. The inactive scrubber bed may be regenerated while it is inactive. When the active scrubber bed becomes sufficiently saturated, the control system may switch the active scrubber bed, using the regenerated bed as the active scrubber bed and allowing the saturated bed to be regenerated. Before switching, the regenerated bed is purged to reduce the oxygen level, which increased during regeneration. First, a volume of low oxygen air is salvaged from the active scrubber bed. The low oxygen air may be salvaged by moving it back into the CA room or into a storage reservoir, such as an air bag. The salvaged low oxygen air may then be moved into the regenerated scrubber bed to reduce the oxygen content in that bed. After the low oxygen air has been introduced into the regenerated scrubber bed, a nitrogen purge process may be used to further reduce the oxygen content in the regenerated scrubber bed. Once the desired oxygen level is reached, the regenerated bed may become the active scrubber bed. | 12-27-2012 |
