摘要： A mixed gas is separated with collection of at least one constituent gas. An inlet leads to a blower or other gas compression element through a valve. This blower feeds a chamber which contains media which selectively adsorbs the constituent gas to be collected, such as nitrogen from air. An exhaust from the chamber leads to an exhaust through a check valve. The blower can be reversed after nitrogen has been adsorbed within the chamber to desorb nitrogen and deliver nitrogen back through the blower. The inlet valve is closed after blower reversing and a separate diversion pathway is opened so that nitrogen is delivered from the blower to a nitrogen collection region. A variant system also includes an oxygen collection region on a side of the chamber opposite the blower for collection of both nitrogen and oxygen separated from air simultaneously, or collection of other constituent gases.

摘要： The flow of gas between two vessels, each of which undergoes cyclic changes in gas pressure, is controlled by two check valves installed in parallel between the vessels. The first check valve allows gas to flow from the first vessel to the second vessel when the differential pressure between the vessels exceeds a first value, and the second check valve allows gas to flow from the second vessel to the first vessel when the differential pressure between the vessels exceeds a second value. The gas flow control method is particularly useful in pressure swing adsorption processes.

摘要： A PSA process and system utilizes a combination of cyclic feed, evacuation, purge, and repressurization steps to provide a final gas product enriched in one of the feed components. The process is carried out in a simple system which utilizes a single two-way four-port valve for controlling gas flow between an adsorber vessel and a blower, and the blower is used for the introduction of feed gas into the adsorber and the evacuation of gas from the adsorber. The control of gas flow in either direction between the adsorber vessel and a product gas storage tank is accomplished by two check valves installed in parallel between the vessel and the tank.

摘要： 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.
摘要翻译：浓缩器通过真空挥发吸附（VSA）的过程将一种气体（即氧）与气体混合物（即空气）分离。吸附剂材料位于吸附床内。吸附床具有入口和出口。阀门位于出口的下游。在吸附器床的上游设置诸如鼓风机的泵，以将混合气体驱动到吸附器床中。吸附剂材料选择性地吸附不期望的气体（即氮气），从混合物中留下所需的气体（即氧气），以通过出口并通过阀门。泵是可逆的。当吸附剂材料饱和时，泵反向并在吸附器床上抽真空。泵在相反方向运行时关闭阀门。在吸附材料解吸不需要的气体之后，泵再次反转并重复循环。
