Definitions

  • the conductivity of a composition made by mixing the purified lignin-based filler with distilled water or water that has been subjected to reverse osmosis is less than 400 pS/cm, or less than 300 pS/cm, when measured at an 8 weight-% dry matter content.
  • the conductivity may be measured according to standard SFS-EN 27888 (1994) .
  • the first solid-liquid separation process is carried out for 15 seconds - 30 minutes , or 30 seconds - 15 minutes , or 1 - 5 minutes .
  • the second solid-liquid separation process is carried out for 2 - 60 minutes , or 3 - 30 minutes .
  • the third solid-liquid separation process is carried out for 2 - 60 minutes , or 3 - 30 minutes .
  • the first solid-liquid separation process is carried out before the washing process .
  • the total dry matter content of the slurry is adj usted to 1 - 15 weight-% .
  • the re-slurried lignin-based filler is then fed into at least one filtration chamber . Then the re-slurried lignin-based filler is subj ected, in the embodiment of Fig . 2 , to a third solid-liquid separation process in the filtration chamber for 2 - 60 minutes at a membrane pressure of 3 - 20 bar . The third solid-liquid separation process is followed by recovering the lignin-based filler from the filtration chamber .
  • purified lignin-based filler is formed to be used in further applications .
  • the recovered lignin-based filler may be dried by applying a drying medium through the lignin-based filler.

Abstract

L'invention concerne un procédé de purification d'une charge à base de lignine. Le procédé consiste à fournir une suspension épaisse comprenant une charge à base de lignine et à soumettre la suspension fournie comprenant une charge à base de lignine à un traitement de purification comprenant un processus de lavage pour former une charge à base de lignine purifiée ayant une teneur en cendres de 0,1 à 3 % en poids sur la base de la teneur totale en matière sèche de la charge à base de lignine. L'invention concerne en outre la charge à base de lignine purifiée pouvant être obtenue selon le procédé tel que défini dans la spécification actuelle.
