  • Method of Desulfurizing Flue Gas, an Arrangement for Desulfurizing Flue Gas, and a Method of Modernizing a Desulfurization Arrangement
    Publication number: 20120189522
    Abstract: A method of desulfurizing flue gas in connection with oxy-combustion. A sulfur containing gas flow is introduced to a flue gas desulfurization arrangement having a spray tower at its top part and a reaction tank at its bottom part, in which the reaction tank contains liquid slurry having a surface level L. Sorbent-containing liquid slurry is sprayed to the sulfur containing gas flow. Sulfur-containing molecules are allowed to be absorbed into liquid slurry droplets. The liquid slurry droplets are allowed to enter the liquid slurry in the reaction tank. Oxygen containing gas is bubbled in the liquid slurry from a gas inlet header and nozzles in the reaction tank, in which the nozzles are arranged at a certain level in the reaction tank. Sulfur-containing particulates settle in the reaction tank.
