Pulping and Bleaching Track

This track is organized by the Alkaline Pulping and Bleaching Committee 

This committee focuses on the process of alkaline pulping and related chemical recovery and regeneration, fiberizing, washing, screening, and other operations prior to stock preparation; the methods and apparatus for other operations such as fibrous raw materials preparation, bleaching, effluent treatment, and recovery of chemical products to the extent that these specifically influence or are influenced by the pulping processes. The investigation and dissemination of knowledge relating to the delignification and/or brightening of pulps of all yield ranges (other than for chemical conversion) by means of one or more chemical treatments; the preparation and evaluation of delignification and bleaching agents and solutions, and the developments of test methods relating to these processes. The investigation and dissemination of knowledge relating to the efficient supply, preparation, handling and storage of woody fiber raw material (including wood waste fuel) for other pulp, paper and paperboard industry.

Conference-goers are invited to attend the Alkaline Pulping and Bleaching Committee Meeting at PEERS and learn more about the activities of this committee and how to get involved in the planning of future conference programs.

The Alkaline Pulping and Bleaching Committee meeting will be held on Sunday, October 27th from 4:00pm - 5:00pm.

 

The purpose of the Pulping and Bleaching track is to disseminate new developments in the production of alkali pulp, provide information on best practices and optimization, and address operational issues.

Presentations will cover the latest developments in pulping optimization, digester operations, brown stock washing, bleaching optimization, bleaching chemistry, and bleaching equipment. The track also offers a tutorial on the pulping process.

Why Should You Attend/Learning Outcomes?

You will:
1. Learn the latest developments in the alkali pulp and bleaching process;
2. Identify potential process enhancements your mill or organization can implement;
3. Hear solutions to a number of issues that can impact the efficiency, reliability and profitability of your operation.

Who Should Attend?

“GPI West Monroe Digester Optimization Project"

Presenter: Kari Lampela of Valmet


Today’s pulp and paper mills operate under constant pressure to reduce production costs and increase yields. The kraft pulp digester operation plays a critical role in the whole pulp mill economy and consistent pulp quality has a direct impact on bottom line profits. To maintain quality targets, digester optimization through continuous cooking alkali profile management has become increasingly important.

Recently, Valmet Inc. and Graphic Packaging International (GPI) collaborated on a continuous digester optimization project with the goal to reduce kappa variation, ease up operation and increase the yield and paper mill runnability. The project, involving three digesters at GPI’s West Monroe facility, had significant results including a 50% reduction in digester blow kappa variations.
