Abstract

L'INVENTION SE RAPPORTE A UN PROCEDE UNIQUE D'EXTRACTION DU SO A DOUBLE BOUCLE, POUR EFFECTUER LA DESULFURISATION DES GAZ DE COMBUSTION. LE PROCEDE COMPREND LES ETAPES SUIVANTES: A.LAVAGE DU COURANT GAZEUX AU MOYEN D'UNE PREMIERE BOUE AQUEUSE CONTENANT DES MATIERES ALCALINES; B. EPURATION DU COURANT GAZEUX LAVE AU MOYEN D'UNE SECONDE BOUE AQUEUSE CONTENANT DES MATIERES ALCALINES; C.MAINTIEN DE LA TENEUR EN MATIERES SOLIDES ALCALINES DANS LA BOUE D'EPURATION; D.MAINTIEN DE LA TENEUR EN MATIERES SOLIDES ALCALINES DANS LA BOUE DE LAVAGE. APPLICATION A LA DESULFURATION DES GAZ DE COMBUSTION.THE INVENTION RELATES TO A UNIQUE DOUBLE-LOOP SO EXTRACTION PROCESS, TO PERFORM THE DESULFURIZATION OF THE COMBUSTION GASES. THE PROCESS INCLUDES THE FOLLOWING STEPS: A.WASHING THE GAS CURRENT BY MEANS OF A FIRST AQUEOUS SLUDGE CONTAINING ALKALINE MATERIALS; B. PURIFICATION OF THE WASHED GAS CURRENT BY MEANS OF A SECOND AQUEOUS SLUDGE CONTAINING ALKALINE SUBSTANCES; C. MAINTAINING THE CONTENT OF SOLID ALKALINE MATTERS IN THE SEWAGE SLUDGE; D. MAINTAINING THE CONTENT OF SOLID ALKALINE MATTERS IN THE WASH SLUDGE. APPLICATION TO THE DESULFURATION OF COMBUSTION GASES.
