20140308185 | METHOD FOR PRECIPITATING MERCURY FROM FLUE GASES OF HIGH-TEMPERATURE PLANTS - The invention relates to a process for separating mercury out of flue gases from high-temperature plants, especially from power plants and waste incineration plants, in which reactants, for example in the form of bromine or alkali metal sulfides, are added to the flue gas beyond the firing operation in flow direction and then the flue gas is subjected to at least one dry cleaning operation for removal of the mercury and any excess reactants, wherein it is a feature of the process that the reactants and carbonaceous adsorbents in the form of activated carbons and/or activated cokes are introduced to the flue gas stream with separate metered addition, and the reactants are metered into the flue gas stream as a function of a preferably constantly measured mercury concentration. | 10-16-2014 |
20120308454 | METHOD FOR REMOVING MERCURY FROM FLUE GASES OF HIGH-TEMPERATURE PLANTS - The invention relates to a method for removing mercury from flue gases of high-temperature plants, in particular of power plants and waste incineration plants, in which method bromine and/or compounds containing bromine are added to the flue gas after firing in the flow direction. The flue gas is then subjected to at least one dry scrubbing process to remove the mercury and perhaps excessive bromine and/or excessive bromine compounds. The method according to the invention is characterized in that the bromine and/or the bromine compounds are brought in contact with the flue gas at a flue gas temperature ranging from 80° C. to 490° C., preferably from 80° C. to 250° C. | 12-06-2012 |
