Abstract
Procedure for the combined manufacture of sulfuric acid and ammonium sulfate, characterized in that the waste gases from the first part of an intensive manufacturing apparatus for sulfuric acid by the action of nitrogen oxides, after the conversion of a Approximately 80% SO2 in sulfuric acid and the cooling and subsequent oxidation of unabsorbed nitrogen oxides are brought into intimate contact with a solution containing free NH3 that binds the gaseous compounds of nitrogen and sulfur in the form of salts ammoniacal, which solution is then decomposed by the action of hot sulfurous gases and sulfuric acid, with the production of ammonium sulfate, releasing the gaseous compounds of nitrogen and sulfur that reincorporate in the cycle.
