Introduction to Kraft Pulping and Bleaching Course

Introduction to Kraft Pulping and Bleaching Course

Peachtree Corners (Metro Atlanta) GA, USA
Tuesday, August 13, 2019 to Wednesday, August 14, 2019

This introductory to intermediate-level course will help you expand your overall understanding of kraft pulp mill operations and broaden your awareness of how one part of the process affects other operations. With this knowledge, you'll be better equipped to troubleshoot quality problems and feel more confident in your interactions among process engineers and operators.

August 13-14, 2019

This is one of TAPPI's most successful annual training courses, offered for ten years!

The overall course objectives are to:

  • Expand your overall understanding of kraft mill operations
  • Broaden awareness of how one part of the process impacts other operations
  • Demonstrate the effect of process variables on kraft pulp quality
  • Build your confidence for effective interaction among new and experienced engineers and operators
  • Lay the initial foundation for you to troubleshoot product and process problems

For suppliers and others at the mill, this course will help you:

  • Understand product performance and pulp quality by knowing the differences in wood and fiber variations.
  • Provide the basics in troubleshooting, optimization and control by better understanding "why things happen" in pulping and processing - the variables affecting pulp quality.

In helping you learn these outcomes and more, Course Chair, Dr. Michael Kocurek, shares his collection of more than 1,000 visuals during the Course Schedule, which you'll have for review later at the mill.

Attendees will receive the visuals in a printed Notebook, and in color on a PDF flash drive.

This is the most comprehensive two-day introductory to intermediate-level course on Kraft Pulping and Bleaching in the industry.

Introductory-Level Content (70%)
The curriculum will cover “what happens,” including:

  • Vocabulary and Overview of Pulp Processes and Technology
  • Raw Materials - Wood and Chip Properties and Effects on Pulping
  • Equipment Overviews and Descriptions
  • Pulp Properties and Tests
  • Preparation of White Liquor in Chemical Recovery
  • Effects of Pulping on Pulp Properties
  • Effect of One Part of the Pulp Mill on Other Parts
  • Brown Stock Washing, Screening and Cleaning
  • Bleaching Fundamentals and Technology
  • Tall Oil, Turpentine and Lignin Recovery
  • Trends in Pulping, Bleaching and Washing
  • Bio-Refinery, Lignocellulose and Nanomaterials Overview
  • Environmental Control Overview

Intermediate-Level Content (30%)
The curriculum also includes discussions on:

  1. What Happens in the Digesters - Lignin, Cellulose, Hemicellulose Reactions
  2. Pulping, Pulp Processing and Bleaching Variables, “Why Things Happen”
  3. Pulp Yield Increase Strategies and Developments

These topics provide the foundations for future learning of more advanced topics at the mill, such as optimization and troubleshooting, which are mill-specific.

Course Learning Objectives:

Kraft Pulping and Processing

  • Become familiar with pulping and bleaching terminology
  • Increase knowledge of the most common pulp properties/tests
  • Understand wood fiber and wood and chip preparation
  • Learn the major types of equipment (Batch & Continuous Digesters) used in kraft pulping
  • Gain an overview perspective of the primary operations and reactions that occur in the digesters between wood and pulping chemicals
  • List several major pulping variables and gain an overview of major kraft pulping trends
  • Understand pulp processing (washing, screening, cleaning) and by-product recovery basics


  • Increase understanding of the bleaching sequences, variables, and bleaching reactions


  • Build greater awareness of pulp mill environmental challenges

Pre-Course Survey
In order to build the best foundation for more advanced topics that are most important to you, Dr. Kocurek conducts a pre-course survey to determine:

  • What are your specific learning objectives and what would you like to take away?
  • What is a specific technology related “hot topic” for your mill or company?
  • What process related troubleshooting topic would you like to see discussed as a basic level case study?

Your answers will contribute to some customization, within the scope and available time, to increase the value of the course.

Who Should Attend
The TAPPI Introduction to Kraft Pulping and Bleaching course is ideal for anyone new to the kraft pulping process, particularly process engineers, machine operators, kraft pulp operators and suppliers.

For new employees and those moving to new positions...

  • A more rapid, in depth and enhanced completion of their training;
  • The ability to learn and gain additional knowledge more easily when interacting with any experienced mill people or suppliers; and
  • Having the foundation of knowledge to take on more advanced projects, including troubleshooting both process and pulp quality problems.

Dr. Michael Kocurek shares more than 40 years experience.

Meet Dr. Michael Kocurek
Dr. Kocurek, Professor Emeritus of Paper Science & Engineering at North Carolina State University, is one of the world's most recognized educators in the pulp and paper industry.  

His focus is on Pulp & Paper Technology, Linerboard Manufacture, Tissue Manufacture, Paper Properties, and Workforce and Professional Development.

He has taught students and thousands of industry operators and professionals at more than 200 mills and 50 paper industry corporations, government and other organizations, including TAPPI, the Department of Energy (DOE), Environmental Protection Agency (EPA), and the American and Forest Association (AF&PA).  Additionally, he has taught undergraduate and graduate students since 1970.

Dr. Kocurek has developed seven distance e-Learning P&P technical courses under a National Science Foundation (NSF) grant at Coastal Alabama.

He is the course chair for TAPPI's oldest and highly ranked short course on Introduction to Pulp & Paper Technology  (for 44 years). He is the editor of 11 books, including the recognized Pulp and Paper Manufacture series covering the entire field of pulp & paper. He has authored and/or co-authored 25 video publications, including the Introduction to Pulp & Paper series- again covering the entire field of pulp & paper.

Dr. Kocurek received his B.S., M.S., and PhD degrees in Paper Science & Engineering from the SUNY College of Environmental Science & Forestry, and Syracuse University. He has served as Paper Science Department Head at the University of Wisconsin-Stevens Point, an academic program he founded; and NC State University. He also has served as Executive Director of the Herty Foundation, an authority agency of the State of Georgia. While at Herty, he oversaw a $27 million modernization of the laboratory, creating the largest pilot scale P&P and advanced fiber development center in the US.

His honors include TAPPI Fellow, TAPPI Distinguished Service Award, TAPPI Paper and Board Division Technical Achievement Award; and induction into the Paper Industry International Hall of Fame - an honor bestowed to recognize people who have made preeminent contributions to the global paper industry.

Specifically About This Course
Dr. Kocurek says, "The Introduction to Kraft Pulping and Bleaching Course is the kind of training that offers a view of the entire puzzle, so to speak, rather than a detailed focus on one or two operations.  There are few if any other courses that combine this field of focus into one. This is an ideal course for anyone who wants to better understand kraft pulping and bleaching operations and processes, pulp grades and products, and what they can do to enhance their own job performance.”

Kraft Recovery Boilers

By Adams, T.N., Frederick, W.J., Grace, T.M., Hupa, M., Lisa, K., Jones, A.K., Tran, H.

This comprehensive textbook covers recovery boilers in great depth and pulls together information on combustion, safety, emissions, plugging, and corrosion. The book also covers fundamental chemical and mechanical engineering principles that bear directly on black liquor and recovery boilers. It contains information about typical values and the normal range of important variables, plus many example calculations, data tables, and charts of relevant material properties or constants and conversion factors. Written by a team of industry experts, the text includes a great deal of practical information such as simple tests to pinpoint problems, important observations to help understand issues for particular operations, and "rules-of-thumb" that are generally used in the industry. This text was written as a project of AF&PA and published by TAPPI PRESS. 1997. 380 pages, hard cover.
