Abstract: The invention relates to a method for removing sulfur dioxide from a dry gas stream which comprises following steps: (a) adding a hydrogen-peroxide-comprising liquid to the gas stream, sulfuric acid forming from the hydrogen peroxide and the sulfur dioxide and (b) condensing, absorbing or aerosol precipitation of the sulfuric acid formed. The admixed hydrogen-peroxide-comprising liquid is mixed with the dry gas stream in the course of less than 0.3 s in such a manner that the admixed liquid is essentially homogeneously distributed in the gas stream. Furthermore, the invention relates to an apparatus for removing sulfur dioxide from a dry gas stream which comprises at least one atomizing nozzle for adding the hydrogen-peroxide-comprising liquid and a filter or aerosol separator, arranged downstream, in the direction of flow of the gas stream, of the at least one atomizing nozzle, in each case at least one atomizing nozzle being arranged on a cross sectional area of 300 to 350 cm 2 .
