    Abstract: The invention comprises a rotary valve having first and second inlet/outlet flow passages, as well as one or more (preferably between 6 and 8) flow ports. The valve has a plurality of positions simultaneously interconnecting the first and second flow passage to selected flow ports. In a preferred embodiment, the valve has a housing and the flow ports are disposed on outer peripheral walls of the housing. The valve may further include an internal rotary plug that is rotatable about a longitudinal axis to move between the positions, and containing openings to connect the flow passages to the flow ports. The plug may be divided into two chambers in the valve which may or may not be moved independently of each other. The valve may further include a movable seal between the housing and the internal plug member which is retractable to permit freer movement of the plug.

    Abstract: A vacuum pressure swing adsorbent (VPSA) system and method for separating a component from a fluid mixture and including a fluid source for introducing the mixture into the system and a supply apparatus for collecting the separated component. A pair of adsorbent bed vessels is interposed between the fluid source and the supply apparatus to adsorb and desorb a predetermined component under respective adsorption and desorption pressures characterized by a low pressure ratio and relatively high desorption pressure values. Implementation of a single-stage vacuum device made possible by the use of the high desorption pressure, results in further reduction in both equipment and operating costs.

    Abstract: A vessel for use in a pressure swing adsorption gas separation process includes an enclosing wall which defines an enclosed space having a top region and a bottom region. An annular adsorbent bed is positioned within the enclosed space and has a porous outer wall, a porous inner wall and adsorbent material positioned between the walls. The porous outer wall is separated from the enclosing wall to create a gas feed channel therebetween, and the porous inner wall surrounds an inner tank whose wall surface is separated from the porous inner wall and creates a product flow channel therebetween. A gas feed/distribution baffle structure is positioned in the bottom region of the vessel and in fluid communication with the gas feed channel to provide a gas feed thereto. The gas feed enters the gas feed channel and the adsorbent bed via the porous outer wall and in a direction generally radially towards the inner porous wall and product flow channel. A product outlet is positioned in the bottom region and in fluid communication with the product flow channel, for collecting product gas passing thereinto via the porous inner wall from the adsorbent bed. A flexible membrane extends between the porous outer wall and the porous inner wall, at the upper extremities thereof, and is pressurized so as to bear upon the upper surface of the adsorbent material to prevent fluidization during gas flow.

    Abstract: A pressure swing adsorption process for the recovery of oxygen from air improves upon a prior art process by depressurizing the adsorbent bed within an adsorbent vessel to an intermediate pressure by releasing void space gas from the product end of the vessel to a low purity oxygen tank while concurrently evacuating the adsorbent vessel from the feed end. This action enables an increased speed of depressurization and a reduction of the cycle time. Further, the adsorbent bed is repressurized to an intermediate pressure from the product outlet end with gas from the low purity oxygen tank, while concurrently pressurizing the adsorbent vessel from the input feed end. This action increases the load time fraction for a feed/vacuum blower. Further, oxygen is introduced to the product end of the adsorbent bed vessel from a high purity oxygen tank (which provides product to downstream applications) while concurrently, air is introduced to the feed end of the adsorbent bed within the vessel. This enables an increased speed of increase in pressure in the bed from the intermediate desorption pressure. Next, a reduction in pressure ratio during the cycle elevates the pressure within the desorption vessel to approximately 7 psia, thereby reducing the evacuation requirements placed on the feed/vacuum blower. The above actions enable achievement of efficiency improvements on the order of 10%.

    Abstract translation: 通过从现有技术的方法回收氧气的变压吸附方法通过将吸附剂容器内的吸附剂床减压到中间压力，通过从容器的产品端释放出空隙气体到低纯度的氧气罐，同时 同时从吸入端排出吸附剂容器。 该动作能够提高减压速度和减少循环时间。 此外，吸附床用来自低纯度氧气罐的气体从产品出口端再加压到中间压力，同时从输入进料端加压吸附剂容器。 该作用增加了进料/真空鼓风机的载荷时间分数。 此外，氧气从高纯度氧气罐（其向下游应用提供产品）引入吸附床容器的产品端，同时空气被引入到容器内的吸附剂床的进料端。 这使得能够从中间解吸压力提高床中压力的增加速度。 接下来，循环期间的压力比的降低将解吸容器内的压力提高到约7psia，从而降低了对进料/真空鼓风机的排气要求。 上述措施可以实现10％的效率提升。

    Abstract: An apparatus includes a vessel and a radial adsorption bed within the vessel and either an axial adsorption bed for a storage tank within the inner diameter of the radial adsorption bed. In one example, the radial adsorption bed surrounds an axial adsorption bed. A process that can be conducted in the vessel includes directing a gas mixture across the radial adsorption bed, thereby causing adsorption of at least a portion of a gas component present in the gas mixture and producing partially purified product. The partially purified gas is directed through the axial adsorption bed, thereby causing further purification of the partially purified gas and producing product gas. In another example, the radial adsorption bed surrounds a storage tank. The storage tank can be employed to store a gas generated or used in a separation process conducted in the radial adsorption bed. For instance, the storage tank can be employed to store product gas or void gas generated in a vacuum/pressure swing adsorption process.
