Abstract

L'invention concerne un procédé de conversion de saumures sulfitiques ammoniacales en dioxyde de soufre au moyen de bisulfate d'ammonium, le sulfate d'ammonium résultant étant décomposé en ammoniac et en bisulfate d'ammonium fondu Le procédé est caractérisé en ce que le bisulfate d'ammonium fondu est mélangé, avant d'être recyclé à l'étape de conversion des saumures sulfitiques, avec un courant d'une solution aqueuse de bisulfate d'ammonium. L'invention est applicable dans les installations d'épuration de gaz contenant du dioxyde de soufre produisant des saumures sulfitiques ammoniacales que l'on régénère par acidification au moyen de bisulfate d'ammonium provenant du bain de sulfate d'ammonium fondu de l'installation.
