Abstract

Mathematical models have been developed for a peroxide bleaching plant based on first principles. Responses of the final pulp brightness to changes in chemical charge, incoming pulp properties and operating conditions have been studied by dynamic simulations. It was found that the chemical charge is the most important variable in determining the final pulp brightness. The simulation of different control strategies showed that a combination of feed-forward and feedback control can achieve good brightness control
