  • Methods for applying microchannels to separate gases using liquid absorbents, especially ionic liquid (IL) absorbents
    Patent number: 8221528
    Abstract: Methods of using microchannel separation systems including absorbents to improve thermal efficiency and reduce parasitic power loss. Energy is typically added to desorb a solute and then energy or heat is removed to absorb a solute using a working solution. The working solution or absorbent may comprise an ionic liquid, or other fluids that demonstrate a difference in affinity between a solute and other gases in a solution.
    Type: Grant
    Filed: August 1, 2008
    Date of Patent: July 17, 2012
    Assignee: Velocys, Inc.
    Inventors: Anna Lee Y. Tonkovich, Robert D. Litt, Ravi Arora, Qiu Dongming, Micheal Jay Lamont, Maddalena Fanelli, Wayne W. Simmons, Laura J. Silva, Steven Perry
  • Methods for applying microchannels to separate methane using liquid absorbents, especially ionic liquid absorbents from a mixture comprising methane and nitrogen
    Patent number: 8029604
