  • Multi-stream microchannel device
    Patent number: 8685365
    Abstract: Provided 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 combining of a plurality of integrated microchannel devices to provide the benefits of large-scale operation is enabled. In particular, the microchannel 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.
    Type: Grant
    Filed: January 22, 2013
    Date of Patent: April 1, 2014
    Assignee: Velocys, Inc.
    Inventors: James A. Mathias, G. Bradley Chadwell, Annalee Y. Tonkovich, Steven T. Perry, Matthew B. Schmidt, Sean P. Fitzgerald, David J. Hesse, Thomas D. Yuschak, Bin Yang

  • Active microchannel fluid processing unit and method of making
    Patent number: 6490812
    Abstract: The present invention is an active microchannel fluid processing unit and method of making, both relying on having (a) at least one inner thin sheet; (b) at least one outer thin sheet; (c) defining at least one first sub-assembly for performing at least one first unit operation by stacking a first of the at least one inner thin sheet in alternating contact with a first of the at least one outer thin sheet into a first stack and placing an end block on the at least one inner thin sheet, the at least one first sub-assembly having at least a first inlet and a first outlet; and (d) defining at least one second sub-assembly for performing at least one second unit operation either as a second flow path within the first stack or by stacking a second of the at least one inner thin sheet in alternating contact with second of the at least one outer thin sheet as a second stack, the at least one second sub-assembly having at least a second inlet and a second outlet.
