  • Publication number: 20080025884
    Abstract: Integrated Combustion Reactors (ICRs) and methods of making ICRs are described in which combustion chambers (or channels) are in direct thermal contact to reaction chambers for an endothermic reaction. Particular reactor designs are also described. Processes of conducting reactions in integrated combustion reactors are described and results presented. Some of these processes are characterized by unexpected and superior results, and/or results that can not be achieved with any prior art devices.

  • Publication number: 20060249020
    Abstract: The disclosed invention relates to a process and apparatus for separating a first fluid from a fluid mixture comprising the first fluid. The process comprises: (A) flowing the fluid mixture into a microchannel separator in contact with a sorption medium, the fluid mixture being maintained in the microchannel separator until at least part of the first fluid is sorbed by the sorption medium, removing non-sorbed parts of the fluid mixture from the microchannel separator; and (B) desorbing first fluid from the sorption medium and removing desorbed first fluid from the microchannel separator. The process and apparatus are suitable for separating nitrogen or methane from a fluid mixture comprising nitrogen and methane. The process and apparatus may be used for rejecting nitrogen in the upgrading of sub-quality methane.

  • Publication number: 20060147370
    Abstract: The invention is a process and device for exchanging heat energy between three or more streams in a microchannel heat exchanger which can be integrated with a microchannel reactor to form an integrated microchannel processing unit. The invention enables the combining of a plurality of integrated microchannel devices to provide the benefits of large-scale operation. In particular, the microchannel heat exchanger of the present invention enables flexible heat transfer between multiple streams and total heat transfer rates of about 1 Watt or more per core unit volume expressed as W/cc.

  • Publication number: 20060108397
    Abstract: Novel methods of making laminated, microchannel devices are described. Examples include: assembly from thin strips rather than sheets; and hot isostatic pressing (HIPing) to form devices with a hermetically sealed wall. Laminated microchannel articles having novel features are also described. The invention includes processes conducted using any of the articles described.
