摘要： The adsorption based air separation unit includes an adsorber vessel containing media which selectively adsorbs water vapor and nitrogen preferentially over oxygen. The vessel includes an air entry spaced from an oxygen discharge. At least one dry air tap from the adsorber vessel is located between the entry and the discharge. When the adsorption media is fresh, air entering the adsorber vessel passes through enough of the adsorber vessel to have much of its water vapor removed and only some of its nitrogen removed. The vessel can include multiple taps sequentially further from the entry which can be selectively opened as the adsorption media becomes saturated with water vapor and nitrogen, so that dry air with much of its nitrogen still present can be further tapped from the adsorber vessel. The adsorber vessel thus facilitates production of both oxygen and dry air, such as for use as medical grade air.

摘要： The air separation unit includes a single adsorption bed downstream of a reversing blower and configured to operate on the principle of vacuum swing adsorption. An optimal ambient air pressure to vacuum pressure ratio within an adsorber vessel downstream of the reversible blower is identified. When the air separation unit is operated at ambient conditions where ambient air pressure is different, such as at higher altitude (or lower altitude) a pressure ratio across the blower when drawing a vacuum on the adsorption bed is maintained for optimal blower power to oxygen production performance. Time for recovery of the adsorption bed can also be modified due to the lower absolute pressure achieved within the adsorption bed when the pressure ratio across the blower is maintained. An ASU is thus provided which is optimized for performance at various different altitudes without requiring modification of equipment within the ASU.

摘要： The adsorber vessel is configured for radial flow between a center column and a perimeter manifold. Space between the center column and the perimeter manifold contains adsorption media. End caps close off ends of the vessel. An inlet and an outlet are configured within one of the end caps to feed starting gas into the center column or perimeter manifold, and to draw off product gas from the perimeter manifold or center column. An end cap can be removed to provide access for media loading between the center column and the perimeter manifold. Media is preferably provided within cartridges which can slide into this media space. Cartridges can be concentric with one cartridge inboard of the other, or can be stacked vertically. A spring plate can be provided on an open end to hold the media in position, while sealing the open end of the adsorber vessel.

摘要： An exemplary single bed reversing blower adsorption based air separation unit is configured to follow the O2 load placed thereon by adjusting flow rates therethrough and power consumption. At least one and preferably multiple pressure sensors sense O2 pressure within an O2 storage region downstream of an adsorber vessel. These sensed pressures are utilized to generate control signals controlling flow rates at locations upstream of the compressor, such as at a reversible blower and an output compressor. Control loops for the blower and the compressor are independent of each other and have different time constants. Effective following of the O2 load is thus achieved without driving the air separation unit into operational conditions outside of design and also maintaining optimal power consumption for the O2 produced, such that efficiency is maintained over a large turndown ratio.
摘要翻译： 示例性的单床换向鼓风机吸附型空气分离单元被配置为通过调节流过其中的流量和功率消耗来跟随其上放置的O2负载。 至少一个并且优选地多个压力传感器感测吸附器容器下游的O 2存储区域内的O 2压力。 这些感测压力用于产生控制信号，该控制信号控制压缩机上游位置处的流量，例如在可逆鼓风机和输出压缩机处。 鼓风机和压缩机的控制回路彼此独立，具有不同的时间常数。 因此，无需将空气分离单元驱动到设计之外的操作条件下，并且还保持所产生的O2的最佳功率消耗，从而实现了O 2负载之后的有效跟随，使得在大的调节比下保持效率。

摘要： A driving system for a reversing blower adsorption based air separation unit is configured to not only drive the reversing blower cyclically in a forward and in a reverse direction, but also to allow the reversing blower to coast during a portion of its operating cycle. While coasting, a pressure differential across the blower acts alone to switch the reversing blower between a forward and a reverse direction of operation. Less power is thus required. When coasting, the blower can also be configured to output power such as the drive motor functioning as an electric generator or by having a mechanical power input be driven by the blower for power generation and/or energy storage. Such a system beneficially utilizes the energy associated with the pressure differential across the blower for energy harvesting and to further accelerate cycle times for the reversing blower adsorption based air separation unit.

摘要： The adsorption based air separation unit includes an adsorber vessel containing media which selectively adsorbs water vapor and nitrogen preferentially over oxygen. The vessel includes an air entry spaced from an oxygen discharge. At least one dry air tap from the adsorber vessel is located between the entry and the discharge. When the adsorption media is fresh, air entering the adsorber vessel passes through enough of the adsorber vessel to have much of its water vapor removed and only some of its nitrogen removed. The vessel can include multiple taps sequentially further from the entry which can be selectively opened as the adsorption media becomes saturated with water vapor and nitrogen, so that dry air with much of its nitrogen still present can be further tapped from the adsorber vessel. The adsorber vessel thus facilitates production of both oxygen and dry air, such as for use as medical grade air.
