O2-X - O2 Delignification

O2-X: Kappa # is a measure of how much lignin is in the wood fiber.

Oxygen reacts with caustic to delignify the pulp in one or two stages.

By controlling caustic to a given Kappa factor, one can optimize the use of cheap oxygen to stabilize the kappa outlet or to maximize delignification, whatever your need is.
