    Abstract: A system provides a boiler (10) integrated with an oxygen producing device (12). Combustion heat generated in the boiler (10 is used to generate steam in the boiler and applied to at least one of a sweep gas stream (13) and a feed gas stream (15) to ensure sweep gas and feed gas streams (12, 15) are provided at the appropriate temperature to the oxygen producing device (12). Flue gas generated by fuel combustion within the combustion chamber (14) may be used as the sweep gas stream (13), in which case, the flue gas exiting the oxygen producing device (12) includes the oxygen removed from the feed gas stream. The flue gas/oxygen mixture may be used for fuel combustion within the combustion chamber, and may be provided to an oxygen separator (28) for removing oxygen from the flue gas. Sensible heat contained in the oxygen depleted feed gas from the oxygen producing device (12) may be recovered by the feed gas stream (15).

    Abstract: Disclosed embodiments address contaminant management challenges that arise during production of desirably contaminant free product fluid in the operation of PSA equipment, and further address the more serious challenges that arise under intermittent operation of PSA equipment. One embodiment includes a breather fluidly coupled to a feed end of an adsorber with a contaminant-sensitive adsorbent. The breather can be coupled to the feed end through a shutoff valve closed during production and open during shutdown. Other embodiments use particular sealing strategies for additional sealing of the apparatus, or at least components thereof, from contaminant ingress. For example, a buffer seal for receiving a buffer gas having a contaminant vapor content substantially the same as or less than a product gas produced by a pressure swing adsorption process over the adsorbers. As a second example, a parking seal can be used that typically is engaged when the apparatus is parked.

    Abstract translation: 公开的实施例解决了在PSA设备的操作中生产期望的无污染物质流体期间产生的污染物管理挑战，并且进一步解决了在PSA设备的间歇操作下出现的更严重的挑战。 一个实施例包括与污染物敏感的吸附剂流体耦合到吸附器的进料端的通气孔。 呼吸器可以通过在生产期间关闭的截止阀与关闭时关闭时打开相连接。 其他实施例使用特定的密封策略来附加地密封设备，或至少其组件，以免污染物进入。 例如，用于接收缓冲气体的缓冲密封件，该缓冲气体的污染物蒸汽含量基本上等于或小于通过吸附器上的变压吸附过程产生的产物气体。 作为第二示例，可以使用通常在设备停放时接合的停车密封件。
