View Track Schedule


The purpose of the Alkaline Pulping and Bleaching track is to disseminate new developments in the raw materials, production and characterization of pulp, present methods and exemplary data for optimizing the process, and address issues in various unit operations.

Presentations will cover developments in liquor optimization and digester operation, washing control/optimization and defoaming, black liquor concentration and oxidation, oxygen delignification theory and modeling, peracetate, ozone and chlorine dioxide bleaching chemistry and optimization. Presentations addressing new detectors and applications are included.

Learning outcomes: After successfully completing the sessions in this track, participants will be able to go back to their workplace and:

Demonstration of learning outcomes: After attending the alkaline pulping and bleaching presentation sessions attendees will have a better understanding of how to implement:
