NEW!  Lime Kilns and Recausticizing: The Forgotten Part of a Kraft Mill

Learn the Operation of the Calcium Cycle.  Designed for entry-level and operating engineers who are new to the industry, this new release serves as both a training resource and as an in-depth reference guide and refresher for engineers in this area of the mill that is often overlooked in most textbooks. This new resource reviews the entire kraft chemical recovery cycle, lime kiln chemistry and includes 11 chapters dedicated to all areas of the kiln, both process and mechanical.  Learn about: recausticizing chemistry, green scale formation, recausticizing equipment, and recausticizing process control.


Black Liquor Evaporation

Explore the Science, Technology, and Practice of Successfully Concentrating Black Liquor from Weak Liquor to Firing Concentrations.  This book is a practical reference for engineers and operators involved with black liquor evaporator operations and troubleshooting, as well as a reference for process-related aspects of evaporator design.  This is the first comprehensive book to deal solely with the topic of black liquor evaporation.


Brownstock Washing

Brownstock washing is the heart of kraft pulp mill operation.  Each system needs to be completely understood from a theoretical and fundamental perspective.  This book reviews current state-of-the-art methods for designing and operating brownstock washing systems, including different types of washers and methods for troubleshooting these washer systems.  Current types of instrumentation and process control of washing systems are also highlighted. Topics covered include: Brownstock Washing, washer control strategy, fundamentals of washing, impact of washing on other areas of the mil,l and troubleshooting.  Designed to be a tool for industry engineers; today’s young engineers in the industry may not have had formal education and training due to omission of the subject from many curricula.


Fundamental of Kraft Recovery

This book details the chemical engineering fundamentals of the kraft recovery process, including mass and energy balances, thermodynamics, fluid dynamics, phase separations, heat and mass transport phenomena, and reaction kinetics. Each kraft recovery unit operations, including multiple effect evaporation, recovery boiler operations, green liquor processing, causticizing, and white liquor processing is discussed in detail.

Sample problems are posed and detailed solutions are presented. Additional instructive process problems are included at the end of each chapter for analysis and solution by the reader. This book is ideal for senior or graduate level courses for pulp and paper, chemical, and mechanical engineers, as well as a valuable reference resource for practicing pulp mill engineers who want to better understand the kraft recovery process they operate each day.


Kraft Pulping

Liberally illustrated with over 130 diagrams and photographs, this book includes basic formulas and diagrams to explain the structure of wood, variables affecting the quality and handling of wood chips, pulping chemistry and equipment, the pulping process, and black liquor recovery. Includes a glossary of frequently used terms.


Chemical Recovery in the Alkaline Pulping Process

Introduction and Principles of Chemical Recovery, Evaporation and Concentration of Black Liquor, Noncondensible Gases, Tall Oil Soap Recovery, Chemical Recovery and Process Chemistry, Chemical Recovery Equiment, Cooking Liquor Preparation, and Lime Reburning: The Rotary Lime Kiln.


The Bleaching of Pulp

Previous editions of The Bleaching of Pulp have provided comprehensive information on the technology used to bleach wood pulps. The 5th edition will continue this tradition as the premiere industry text on bleaching technologies but will be more focused on the modern industrial processes with less emphasis on fundamental science. New or more comprehensive sections are included on elemental chlorine free bleaching, enzymes, acid treatments for hexeneuronic acids, control of mineral scale and multi-stage modeling as used to optimize bleaching among multiple stages.

Chemical Pulping Part 1, Recovery of Chemicals and Energy, 2nd Edition

This book will tell you, step by step, why (research) and how (technology) things are done to obtain fibres from wood by chemical pulping. This book may be unique in combining science and technology in a way that allows both students and mill engineers to benefit from learning about modern fibre lines, while increasing their awareness of the challenges and opportunities involved in research and in the design and operation of new pulp mills anywhere in the world.  Part Papermaking Science and Technology Series, published by the Finnish Paper Engineers’ Association.


Chemical Pulping Part 2, Recovery of Chemicals and Energy, 2nd Edition

This book covers kraft pulp mill technology from fibre line spent liquor — black liquor — to the recovered active cooking chemical — white liquor — and energy in the form of steam and electricity. The modern “megaton”- scale technologies of evaporation, recovery and bark boilers, re-causticising, lime re-burning and tall oil by-products are described in detail and in a process technology textbook manner. Pulp mills’ role as a producer of renewable forest-based energy is significant and growing and this trend is also captured in this book.  Part Papermaking Science and Technology Series, published by the Finnish Paper Engineers’ Association.


Mechanical Pulping, 2nd Edition

The purpose of a mechanical pulping process is to separate the fibres from the wood matrix, hopefully in a form suitable for a specific papermaking process. This is of course a demanding task, and for an outsider it might sound like magic that solid wood at all can be converted into useful fibres just by treating it mechanically. This book covers the basics and fundamentals of mechanical pulping including all the processes related to mechanical pulping.  Part Papermaking Science and Technology Series, published by the Finnish Paper Engineers’ Association.
