Abstract

L'invention concerne un procédé de recyclage de soufre dans un procédé de préparation de pâte chimique, tel qu'un processus de sulfate. Ledit procédé est caractérisé en ce que le sulfate récupéré à partir d'un cycle de processus est converti en bisulfate au moyen d'un oxydant, lequel bisulfate est ensuite réutilisé sous forme d'acide recyclé dans des étapes de processus variées
