What is Brightness Optimization in Pulp Bleaching about?

The document describes an improved model for optimizing brightness in the first bleaching stage of a eucalypt kraft pulp mill. The model uses online measurements of brightness and residual chemicals before pulp enters the bleaching tower, rather than relying on offline kappa number measurements. Applying the model shifted the chlorination stage brightness closer to the target value of 60.7% ISO and reduced the standard deviation from 3.0 to 2.5. The golden section search algorithm was used to find the optim
