Oxygen delignification processes are located between the pulp mill and the traditional bleach plant. The goal of oxygen delignification is to reduce the lignin content of unbleached pulp before using more expensive bleaching chemicals. Even though it has been known to be an effective bleaching chemical for many years, several obstacles prevented commercialization until 1970. The obstacles and their solutions will be discussed in this course along with oxygen delignification processes, equipment, and safety.
