In an earlier investigation, a generalized model was developed to simulate the first chlorine dioxide brightening stage (D1). This stoichiometric model accurately predicts pulp brightness values for given bleach charges and vice versa for laboratory softwood pulps. The equation parameters are dependent upon the kappa number and brightness of the extracted pulp. In this study, the above model was refined to include the negative effects of extraction stage carryover in order to simulate more realistically a bleach plant D1 stage.
