Introduction to Kraft Pulping and Bleaching Course

Peachtree Corners (Metro Atlanta) GA, USA
Tuesday, August 13, 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 13-15, 2019

What will this course help you do?

  • Expand your overall understanding of kraft mill operations.
  • Broaden awareness of how one part of the process affects other operations.
  • Demonstrate the affect of process variables on kraft pulp quality.
  • Build 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.
  • Lay the foundation for 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 800 visuals during the Course Schedule, which you'll have for review later at the mill.

"I now understand terms, can relate to the data and know what questions to ask. I really enjoyed this course and learned alot!" ~Mollie E. Process Engineer, Resolute FP

Dr. Michael Kocurek shares more than 40 years experience.

Dr. Michael Kocurek
Dr. Kocurek at PlantDr. Kocurek is one of the most recognized and preeminent pulp and paper technology educators in the pulp and paper industry.  He has taught this and other pulp and paper courses for more than 47 years to students, and many thousands of industry personnel, including technical, non-technical, and mill operators.  His instruction has been leveraged for TAPPI, other organizations, and at more than 200 pulp and paper mills.  He most effectively delivers a combination of technical and practical mill process technology knowledge to those who have benefitted from his courses. 

Dr. Kocurek has taught this course, the Introduction to Kraft Pulping and Bleaching, for years utilizing more than 40 years of experience.  He also continues as the sole instructor in the TAPPI Introduction to Pulp and Paper Technology course, which he has taught since 1974.  The TAPPI Kraft Pulping and Bleaching course is an expanded, enhanced version of the kraft mill operations material.

"This is the kind of course 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," says Kocurek.  “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.”
