Abstract

Nouveau procédé amélioré de cuisson continue de matière fibreuse, selon lequel les températures et les teneurs en alcalis sont régulées de manière à être maintenues à des niveaux spécifiques dans différentes zones du processus de lessivage afin d'optimiser la consommation de produits chimiques et les économies de chaleur et parallèlement, d'obtenir une pâte présentant d'excellentes propriétés. La matière fibreuse est chauffée et imprégnée à l'aide de liqueur noire à une température inférieure à 140 DEG C et transférée dans un courant principal vers une zone d'imprégnation (A). La matière fibreuse chauffée et imprégnée est transférée dans une zone de cuisson (B) à courant principal située dans une partie supérieure d'un lessiveur (6). Au moins 60 % de la quantité de liqueur (F) requise pour la réaction de cuisson est introduite dans l'extrémité amont de la zone de cuisson (B) à courant principal afin d'obtenir une teneur effective en alcalis dépassant 35g/l. La température de cuisson dans la zone de cuisson (B) à courant principal est inférieure à 160 DEG C. La liqueur épuisée (E), dont la teneur effective en alcalis est d'au moins 13g/l, est retirée par passage à travers une ceinture-filtre (8). Une partie importante de la liqueur épuisée est transférée dans la zone d'imprégnation.
