Introduction to Kraft Pulping and Bleaching Course
Introduction to Kraft Pulping and Bleaching Course
TAPPI Training Room, Peachtree Corners, GA, USA
Wednesday, August 09, 2023 to Thursday, August 10, 2023
The Introduction to Kraft Pulping and Bleaching Course is one of TAPPI's most successful annual training events, offered for more than 12 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 (45%)
This course will have Introductory level content that includes:
- Overview of Processes & Technology (“what happens”)

Bleaching
- Increase understanding of the bleaching sequences, variables, and bleaching reactions
Environmental
- 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

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.”
