E, EO, EOP Extraction Stages

Extraction stages are intermediate stages in the bleaching aimed to dissolute all lignin fragments liberated in previous oxidizing bleaching stages. Many benefits can be gained from using a pressurized extraction stage.

Benefits of pressurized extraction compared to atmospheric:

  • Possibility to integrate extraction action with bleaching action
  • Possibility to significantly increase the brightness due to the possibility of increased consumptions of hydrogen peroxide in beneficial bleaching reactions
