Definitions

  • White liquor is introduced into the digester as "hot white liquor", which has been heated up using the heat of the previously generated spent liquor, and steam.
  • hot is meant to designate a liquor having a temperature above its boiling point at ambient pressure, i.e. a liquor that must be stored in a pressurized vessel.
  • a hot black liquor pre-treatment stage was carried out by introducing hot black liquor (HBL 1, 150°C, app. 20 gEA/1) to the bottom of the digester of the digester, displacing the spent impregnation liquor from the top of the digester (DWBL).
  • the hot black liquor pre- treatment stage duration was 30 minutes.

Abstract

Selon l'invention, on utilise un polysulfure dans la fabrication d'une pâte kraft dans l'étape initiale d'un procédé discontinu de déplacement en vue d'une amélioration du rendement. Une lessive blanche contenant du polysulfure est ajoutée par mélange à la première lessive chargée dans le digesteur, ou sous la forme d'une charge séparée avant l'introduction de la lessive d'imprégnation. De préférence, un catalyseur de cuisson, tel qu'une anthraquinone, est ajouté à la charge de lessive blanche au début de l'étape de cuisson.
