  • Patent number: 6562303
    Abstract: A method and an apparatus for treating flue gas by injection of an aqueous liquid in the form of droplets and subsequent separation thereof are described. In the treatment, the flue gas and droplets are conducted towards a baffle means, on which droplets are deposited and form a liquid film, and the flue gas is made to pass through the liquid film. The apparatus comprises a quencher having an inlet for the flue gas, nozzles for injecting an aqueous liquid in the form of droplets into the flue gas, and an outlet for the flue gas. The apparatus is characterized in that a baffle means is arranged in the path of flow in the flue gas for depositing liquid droplets and forming a liquid film, and that deflection means are arranged under the baffle means.
