摘要： 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 disclosed embodiment of a PSA apparatus, intended primarily for normal operating cycle speeds of at least 3 cycles per minute, 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 disclosed embodiments of the PSA apparatus used particular sealing strategies for additional sealing of the apparatus, or at least components thereof, from contaminant ingress. For example, one embodiment comprises 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. The buffer chamber may have flushing circulation provided by delivered product flow. As a second example of sealing strategy, a parking seal can be used that typically is engaged when the apparatus is parked. The parking seal can be used alone, or in combination with other contaminant management features. Embodiments of a method for reducing adsorbent degradation by contaminant adsorption while producing a product gas also are described comprising providing described embodiments of the PSA apparatus or system, and operating such PSA apparatus or system to produce a product gas. Various embodiments for operating a PSA apparatus and system during normal product delivery, shutdown, park and start up modes also are described.
摘要翻译：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。主要用于每分钟至少3个循环的正常操作循环速度的PSA装置的一个公开实施例包括与吸附器的进料端流体耦合的通气器，其具有污染物敏感性吸附剂。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。 PSA设备的其它公开的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，一个实施例包括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。缓冲室可以具有由输送的产品流提供的冲洗循环。作为密封策略的第二示例，可以使用通常在设备停放时接合的停车密封件。停车密封件可以单独使用，也可以与其他污染物管理功能结合使用。还描述了在制造产品气体的同时通过污染物吸附降低吸附剂降解的方法的实施方案，其包括提供PSA装置或系统的所述实施方案，以及操作这种PSA装置或系统以产生产物气体。还描述了在正常产品递送，关闭，停放和启动模式期间操作PSA装置和系统的各种实施例。

摘要： High temperature fuel cell electrical generation systems are provided that are adapted to enable selective generation of electrical power, and/or hydrogen fuel, and/or useable heat, allowing flexible operation of the generation system. In such embodiments, the high temperature fuel cell may be either a MCFC or a SOFC. The disclosed systems relate to high temperature fuel cells exploiting gas separation devices in which a first gas mixture is to be separated so that a first product of the separation is enriched in a first component, while a second component is mixed with a displacement purge stream to form a second gas mixture, with provision to prevent cross contamination of purge gas components into the first product stream. The process may be applied to hydrogen (component A) enrichment from syngas mixtures such as fuel cell anode exhaust, where dilute carbon dioxide (component B) is to be rejected such as to the atmosphere or for recycle to the fuel cell cathode in the case of molten carbonate fuel cells, by purging with cathode exhaust oxygen-depleted air (as component C).
