Control Kappa reduction in oxygen delignification

Valmet Oxygen Stage Optimizer

The Valmet Oxygen Stage Optimizer enhances oxygen delignification, particularly during disturbances and production changes in rate, pulp grade or wood species.

The oxygen delignification process provides a unique method for lignin removal without degrading the pulp strength. The Valmet Oxygen Stage Optimizer manages the Kappa number development throughout the process.

In addition to higher Kappa reduction, through advanced controls, you can improve Kappa variability and automatically respond to changes in production variables. Use the optimizer to effectively improve Kappa reduction capacity in the oxygen stage for higher production or a higher cooking kappa target.

With your Kappa number under control, you can directly impact chemical consumption. An optimized residual lignin target means the bleaching process requires fewer chemicals to achieve the same brightness target.
