Title (EN) A METHOD OF CONTROLLING HYDROPHOBIC CONTAMINANTS BY UTILIZING A FLUORESCENT DYE
(FR) PROCÉDÉ POUR CONTRÔLER DES CONTAMINANTS HYDROPHOBES À L'AIDE D'UN COLORANT FLUORESCENT
Abstract:
(EN) The present invention pertains to a method of determining the quantity of hydrophobic contaminants in a papermaking process by utilizing a fluorescent dye, to a method of evaluating treatment chemicals for controlling hydrophobic contaminants by utilizing a fluorescent dye, and to a method of optimizing the amounts of treatment chemicals for reducing hydrophobic contaminants in a papermaking process by utilizing fluorescent dye.
(FR) La présente invention concerne un procédé pour déterminer la quantité de contaminants hydrophobes dans un processus de fabrication de papier à l'aide d'un colorant fluorescent, un procédé pour évaluer des produits chimiques de traitement pour contrôler des contaminants hydrophobes à l'aide d'un colorant fluorescent, et un procédé pour optimiser les quantités de produits chimiques de traitement pour réduire des contaminants hydrophobes dans un processus de fabrication de papier à l'aide d'un colorant fluorescent.
