Abstract

La présente invention concerne le domaine de l'élimination des oxydes du soufre. Les anions sulfo-oxygénés des sels thermiquement stables qui se produisent dans un procédé d'absorption sélective de SO2 , en III, par une solution d'agent d'absorption sont extraits : 1 en séparant une portion 120 de cette solution du courant d'agent d'absorption pauvre 113; 2 en mettant cette portion au contact d'un échangeur d'anions fixant lesdits anions sulfo-oxygénés; 3 en renvoyant cette portion dans l'un des courants principaux; 4 en régénérant ladite résine, ce qui donne un courant résiduaire contenant ces anions. L'invention s'applique à la séparation de l'anhydride sulfureux dans les gaz de cheminée des centrales électriques, les gaz effluents des incinérateurs, etc.The present invention relates to the field of the removal of sulfur oxides. The sulfo-oxygenated anions of the thermally stable salts which occur in a process of selective absorption of SO2, in III, by a solution of absorption agent are extracted: 1 by separating a portion 120 of this solution from the stream of poor absorber 113; 2 by bringing this portion into contact with an anion exchanger fixing said sulfo-oxygenated anions; 3 by returning this portion to one of the main streams; 4 by regenerating said resin, which gives a waste stream containing these anions. The invention applies to the separation of sulfur dioxide in the flue gases of power plants, the effluent gases of incinerators, etc.
