Abstract: In a process and an apparatus for the joint purification in a wash column (VII) by means of a washing liquid (5) of the waste gases (1,3) and/or vapors (2) formed in the production of inorganic fertilizers, the waste gases (1,2,3) introduced into the wash column are sprayed with a wash liquid (11) after their entry into the lower part of the wash column. The column is typically a filled column with waste gas distribution elements disposed below the filler and spray nozzles near the distributors.
