  • Method for the recovery of acids from hydrometallurgy process solutions
    Patent number: 8741146
    Abstract: A method for the recovery of acids and other materials from hydrometallurgic process solutions comprising processing said solutions utilizing a simulated moving bed chromatographic method to produce at least two product streams.
    Type: Grant
    Filed: February 28, 2012
    Date of Patent: June 3, 2014
    Assignee: Amalgamated Research LLC
    Inventors: Michael M. Kearney, Michael W. Mumm, Lawrence Velasquez, William Jacob, IV

  • Fractal stack for scaling and distribution of fluids
    Patent number: 6616327
    Abstract: Fluid transporting fractal devices, which can be employed whenever a controlled distribution and/or collection of fluids is desired, are constructed to position fractal stages of either progressively smaller or progressively larger scales along the direction of flow (Plates #1-#8). A preferred construction assigns generations of recursive fractal pattern to plates arranged in a stack.
    Type: Grant

  • Simulated moving bed block displacement procedure
    Patent number: 6200390
    Abstract: A “block” of betaine is displaced from the circulation loop of an ion exclusion system configured as an SMB without disturbing the normal operation of the system. In practice, a betaine-concentrated fraction is withdrawn (17) from the circulating loop of the SMB while an equal volume of water is introduced (15) to the loop. The circulation loop thereby continues without disruption.
    Type: Grant

  • Fluid transfer system with uniform fluid distributor
    Patent number: 5354460
    Abstract: A step-down nozzle for the even distribution of fluids at the interface between phases in a column or cell accommodating a plug flow operation is structured with an internal flow channel of recursive configuration.
    Type: Grant
    Filed: January 28, 1993
    Date of Patent: October 11, 1994

  • Chromatographic separator sorbent bed preparation
    Patent number: 4990259
    Abstract: An equilibrated percent solids waveform is established in a simulated moving bed process. A contraction phase of the waveform is monitored as it rotates through a circulation loop including a plurality of resin bed compartments. The contraction phase is followed by a desorbent phase. A slurry of resin is added to each compartment between the contraction and desorbent phases.
