  • Multi-stream multi-channel process and apparatus
    Patent number: 9441777
    Abstract: Provided is a process and apparatus for exchanging heat energy between three or more streams in a millichannel apparatus, which millichannel apparatus may comprise a heat exchanger which may be integrated with a millichannel reactor to form an integrated millichannel processing unit. The combining of a plurality of integrated millichannel apparatus to provide the benefits of large-scale operation is enabled. In particular, the millichannel heat exchanger 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.

  • Microchannel Apparatus and Methods of Conducting Unit Operations With Disrupted Flow
    Publication number: 20160038904
    Abstract: The invention described herein concerns microchannel apparatus that contains, within the same device, at least one manifold and multiple connecting microchannels that connect with the manifold. For superior heat or mass flux in the device, the volume of the connecting microchannels should exceed the volume of manifold or manifolds. Methods of conducting unit operations in microchannel devices having simultaneous disrupted and non-disrupted flow through microchannels is also described.

  • Integrated combustion reactor and methods of conducting simultaneous endothermic and exothermic reactions
    Patent number: 9192929
    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.
