    摘要： The present disclosure relates to systems and processes for adsorptive gas separations where a first gas mixture including components A and B is to be separated so that a first product of the separation is enriched in component A, while component B is mixed with a third gas component C contained in a displacement purge stream to form a second gas mixture including components B and C, and with provision to prevent cross contamination of component C into the first product containing component A, or of component A into the second gas mixture containing component C. The invention may be applied to hydrogen (component A) enrichment from syngas mixtures, where dilute carbon dioxide (component B) is to be rejected such as directly to the atmosphere, and with preferably nitrogen-enriched air as the displacement purge stream containing residual oxygen (component C).

    摘要： Power plant systems and processes are described that enable recovery of at least a portion of the fuel storage energy associated with a storage system for supplying fuel to the power plant systems. A first embodiment of an energy-recovery power plant system includes at least one fuel storage container and at least one expander that can receive fuel from the fuel storage container at a first pressure and provide the fuel to the power plant at a second pressure that is lower than the first pressure. A second embodiment of an energy-recovery power plant system includes a first conduit fluidly coupling the fuel storage container and the power plant for delivering fuel from the fuel storage container to the power plant and at least one regenerative thermodynamic cycle engine thermally coupled to the first conduit such that heat may be exchanged between the fuel and a working fluid for the regenerative thermodynamic cycle engine.

    摘要： Disclosed embodiments concern adsorptive gas bulk separation systems and methods that may be advantageously less expensive to utilize than some in the prior art. Embodiments of the present invention concern processing a feed gas source, typically comprising at least one fuel gas component and at least one diluent, using a displacement purge adsorptive separator apparatus comprising at least one adsorbent bed, at least one purge gas source for purge regeneration of the at least one adsorbent bed, and a product conduit for supplying upgraded gas product. The feed gas typically is supplied to the displacement purge adsorptive separator apparatus at substantially the ambient pressure of the feed gas source. The displacement purge adsorptive separator apparatus is operable to adsorb at least a portion of the at least one diluent component from the feed gas stream to produce an upgraded gas.

    摘要： An inventive adsorptive gas separation process is provided capable of producing a purified methane product gas as a light non-adsorbed product gas as opposed to a heavy desorbed exhaust gas component, from a feed gas mixture comprising at least methane, and carbon dioxide. In an embodiment of the invention, the feed gas mixture may comprise at least about 10% carbon dioxide, and the purified methane product gas may be desirably purified to contain less than about 5000 ppm carbon dioxide. In another embodiment of the invention, the feed gas mixture may comprise at least about 50% carbon dioxide, and the purified methane product gas may be desirably purified to contain less than about 5000 ppm carbon dioxide.
