  • Method and plant for removing carbon dioxide from flue gas
    Patent number: 8043588
    Abstract: This invention relates to a method and plant for energy-efficient removal of CO2 from a gas phase by means of absorption. The invention is particularly suitable for use in connection with thermal power plants fired by fossil fuels, and is also well-suited for retrofitting in existing thermal power plants. A processing plant according to the invention comprises three sections: a primary CO2-generating process that serves as main product supplier; a CO2-capture and separation plant based on absorption and desorption of CO2 respectively by/from at least one absorbent; and a second CO2-generating process where combustion of carbonaceous fuel in pure oxygen atmosphere serves as energy supply to at least a part of the thermal energy necessary to drive the regeneration of the absorbent in the desorption column(s).
