Pulping and Bleaching
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:
- Identify opportunities to optimize pulping and bleaching processes.
- Address and develop solutions to operational issues.
- Identify areas where advanced sensors and controls may be helpful.
- Optimize process parameters to minimize production costs and maximize profitability
Demonstration of learning outcomes: After attending the alkaline pulping and bleaching presentation sessions attendees will have a better understanding of how to implement:
- Mill trials of equipment designed to improve quality, production, or cost of a process.
- Process engineering changes based on learned information.
- Consultation with experts in the field that were connections made during the conference.
- Mill audits and operational changes to save cost and increase process performance.
- Improved mill environmental performance due to changes made based on learned bleaching chemistry and equipment developments.
