    Abstract: A method and apparatus for separating a separation component from a gas stream. One exemplary method includes: flowing the gas stream across a process surface of a compliant composite heat transfer wall, wherein: the gas stream has an initial concentration of the separation component, and the gas stream has a gas temperature; flowing a cooling fluid across a cooling surface of the wall, wherein: the cooling fluid has a fluid temperature, and the fluid temperature is less than the gas temperature; and producing an output gas stream, wherein: the output gas stream has an output concentration of the separation component, and the output concentration is less than the initial concentration. Another exemplary method includes separating at least a portion of the separation component from the gas stream by: accumulating the portion proximate the process surface; and delaminating the portion from the process surface with a flow of the gas stream.

    Abstract: A continuous thermal hydrogen compression system, and methods of thermally compressing hydrogen, are disclosed. A hydrogenation module accepts a hydrogen gas stream to be absorbed or adsorbed to a lean carrier stream through heat removal, thereby producing a heat output and a rich carrier stream containing absorbed or adsorbed hydrogen. A pump, connected to an output of the hydrogenation module, increases the pressure of the rich carrier stream to produce a pressurized rich carrier stream. A dehydrogenation module separates, via an addition of heat, a pressurized hydrogen gas stream from the pressurized rich carrier stream to produce a lean carrier stream. A pressure reducing device reduces the pressure of the lean carrier stream before it is returned to the hydrogenation module. The carrier stream is cycled continuously between the hydrogenation module and the dehydrogenation module.

    Abstract: A scraped heat exchanger apparatus, including a vessel and a plurality of internally cooled plates disposed parallel to each other within the vessel. A rotating shaft is disposed at a central axis of the vessel. A rotating scraper arm, connected to the rotating shaft, moves between adjacent plates. The rotating scraper arm includes a scraper positioned to scrape solids from the outer surfaces of adjacent plates. A cooling fluid flows through an interior of each plate. The cooling fluid cools a gaseous process fluid flowing between adjacent plates. An opening in each of the plates permits the process fluid, and solids removed from the process fluid and scraped by the rotating scraper arm, to pass through the plates.

    Abstract: A method and apparatus for liquefying a feed gas stream comprising natural gas and carbon dioxide. A method includes compressing an input fluid stream to generate a first intermediary fluid stream; cooling the first intermediary fluid stream with a first heat exchanger to generate a second intermediary fluid stream, wherein a temperature of the second intermediary fluid stream is higher than a carbon dioxide-freezing temperature for the second intermediary fluid stream; expanding the second intermediary fluid stream to generate a third intermediary fluid stream, wherein the third intermediary fluid stream comprises solid carbon dioxide; separating the third intermediary fluid stream into a fourth intermediary fluid stream and an output fluid stream, wherein the output fluid stream comprises a liquefied natural gas (LNG) liquid; and utilizing the fourth intermediary fluid stream as a cooling fluid stream for the first heat exchanger.
