Title (EN) PRODUCTION METHOD FOR DISSOLVING KRAFT PULP
(FR) PROCÉDÉ DE PRODUCTION POUR UNE PÂTE KRAFT DISSOLVANTE
(JA) 溶解クラフトパルプの製造方法
Abstract: front page image
(EN) The purpose of the present invention is to provide a technique for appropriate management of the hydrolysis process during production of dissolving kraft pulp, and appropriate control of the dissolving kraft pulp production process. From the absorbance, at 260-300 nm, of the wastewater from the hydrolysis process during production of dissolving kraft pulp, the condition of the hydrolysis process can be appropriately ascertained, and the quality of the dissolving kraft pulp managed.
(FR) La présente invention vise à procurer une technique pour une gestion appropriée du processus d'hydrolyse pendant la production d'une pâte kraft dissolvante, et pour une commande appropriée du processus de production d'une pâte kraft dissolvante. À partir du facteur d'absorption, à 260 – 300 nm, de l'eau usée venant du processus d'hydrolyse pendant la production de la pâte kraft dissolvante, la condition du processus d'hydrolyse peut être estimée de façon appropriée, et la qualité de la pâte kraft dissolvante peut être gérée.
(JA) 本発明の課題は、溶解クラフトパルプの製造における前加水分解処理を適切に管理し、溶解クラフトパルプの製造プロセスを適切に制御する技術を開発することである。 溶解クラフトパルプの製造における前加水分解処理の排液の260~300nmにおける吸光度によって、前加水分解処理の状態を適切に把握し、溶解クラフトパルプの品質を管理することができる。
