Procedure for obtaining sulfur dioxide based on smoke gases, in which sulfur dioxide is obtained in the form of ammonium sulfate, characterized in that the gases are washed with water, or with ammonia water, and with the simultaneous addition of ammonia, so that approximately 1.3-2.1 moles of NH3 are contained in the lye that is being formed, most conveniently, per 1 mol of SO2, after which the solution enriched with SO2 is optionally neutralized, by means of ammonia, treating the solution at an increased temperature and under also increased pressure, with oxygen, or gases that contain it and, finally, the oxidized solution is concentrated by evaporation.
