Oxygen Delignification System

Oxygen Delignification System

Oxygen Delignification System

Oxygen delignification process is used for dissolving lignin by making use of the strong oxidant effect of molecular oxygen and oxydative degradation in alkaline medium. It has become a necessary process for the production of high brightness chemical pulp. At conditions of medium consistency, pulp is bleached using oxygen as the bleaching agent. This further reduces pulp kappa value. About 40% - 50% of the kappa value of the original coarse pulp can be decreased.

The medium consistency bleaching technology has developed into a mature process. Oxygen delignification process is performed in the oxygen delignification reaction tower. Oxygen delignification reaction tower can be classified into the form of bottom cone & top unloading and bottom distributor & top unloading.
