  • Method and plant for amine emission control
    Patent number: 9155990
    Abstract: A method for eliminating or substantially reducing emission of amines (amineslip) and alkaline degradation products to the atmosphere from a plant for CO2 capture from a flue gas, where the CO2 is captured by counter-current flow to an absorbent in an absorption zone, the absorbent comprising an aqueous solution of one or more amine(s), to give a CO2 lean flue gas that is released into the surroundings, and a CO2 rich absorbent that is regenerated in a regeneration column to give a CO2 rich gas that is treated further, and regenerated absorbent that is recycled to the absorption zone, wherein the CO2 lean flue gas is washed with an acidic aqueous solution to remove or substantially reduce the amount of amine(s) and alkaline degradation products thereof in the gas, is described.
    Type: Grant
    Filed: February 12, 2010
    Date of Patent: October 13, 2015
    Assignee: Aker Clean Carbon AS
    Inventors: Oscar Fredrik Graff, Otto Morten Bade, Oddvar Gorset, Simon Woodhouse
  • Method and plant for COcapturing
    Patent number: 8641994
    Abstract: A method and a plant for capturing CO2 from an exhaust gas from combustion of carbonaceous material are described. At least a part of the combustion gas is introduced into a biol fuel boiler as an oxygen containing gas, to increase the concentration of CO2 and decrease the oxygen concentration in the gas before introduction into an absorption column for separation of CO2.

    Publication number: 20110308389
    Abstract: A method for eliminating or substantially reducing emission of amines (amineslip) and alkaline degradation products to the atmosphere from a plant for CO2 capture from a flue gas, where the CO2 is captured by counter-current flow to an absorbent in an absorption zone, the absorbent comprising an aqueous solution of one or more amine(s), to give a CO2 lean flue gas that is released into the surroundings, and a CO2 rich absorbent that is regenerated in a regeneration column to give a CO2 rich gas that is treated further, and regenerated absorbent that is recycled to the absorption zone, wherein the CO2 lean flue gas is washed with an acidic aqueous solution to remove or substantially reduce the amount of amine(s) and alkaline degradation products thereof in the gas, is described.
