Abstract

Une méthode d'élimination des polluants à partir d'un sous-produit de liqueur d'un procédé de mise en pâte, la méthode comprenant l'injection d'un gaz contenant de l'oxygène dans ladite liqueur et la condensation de la vapeur d'eau du gaz de strippage de manière à produire un condensat comprenant les polluants. Également une méthode de contrôle du débit et/ou de la température d'un sous-produit de liqueur d'un procédé de mise en pâte, le procédé comprenant l'injection d'un gaz contenant de l'oxygène dans la liqueur dans un réacteur, le traitement de la liqueur dans un réservoir de détente de manière à créer une liqueur refroidie et combiner au moins une partie de la liqueur refroidie avec de la nouvelle liqueur lorsque la nouvelle liqueur entre ou lorsque la nouvelle liqueur est dans le réacteur.
