Abstract

PROCEDE CONTINU DE DESULFATATION D'UNE PHASE ORGANIQUE NON SOLUBLE DANS L'EAU D'ACIDE PHOSPHORIQUE CONTENANT DE L'ACIDE SULFURIQUE. ON TRAITE LA PHASE ORGANIQUE A CONTRE-COURANT DANS UNE PREMIERE ZONE AU MOYEN D'UNE SOLUTION AQUEUSE PROVENANT DE LA TROISIEME ZONE DE CONTACT, LA PHASE ORGANIQUE RESULTANTE EST TRAITEE DANS UNE DEUXIEME ZONE AU MOYEN D'UNE SOLUTION AQUEUSE D'IONS BARYUM, PUIS DANS UNE TROISIEME ZONE AU MOYEN D'EAU. LA PHASE AQUEUSE SORTANT DE LA DEUXIEME ZONE EST SEPAREE DU PRECIPITE DE BASO, RECHARGEE EN BARYUM ET RECYCLEE A LA ZONE DE CONTACT. APPLICATION DE L'ACIDE PHOSPHORIQUE OBTENU A L'ALIMENTATION HUMAINE.
