Abstract

Pulp and paper plants use chlorine dioxide, oxygen, and hydrogen peroxide for pulp bleaching. The paper aims at analyzing the effect of oxidative alkali treatment with the addition of oxygen and hydrogen peroxide on hardwood sulphate pulp bleaching using ECF technology. The results of an experiment in assessing the performance of oxygen and hydrogen peroxide in alkali treatment are presented in relation to the conditions prevailing at the Russian plants. The scheme of hardwood pulp bleaching was as follows: D^₀–E (EO, EP, EOP)–D^₁–D^₂; where D – chlorine dioxide treatment, E – alkali treatment (with oxygen, with hydrogen peroxide, and with oxygen and hydrogen peroxide). Evaluation of the experimental findings allows to conclude that the oxygen utilization at the alkali stage is insufficient in pulp bleaching under a pressure of 0.2 MPa. The maximum reduction in the amount of kappa sulfate pulp and a decrease in the consumption of chlorine dioxide at the final bleaching is provided by oxidative alkaline treatment with the addition of hydrogen peroxide with a flow rate of 3.0 kg/t. For the D₀–EOP–D₁–D₂ scheme, the addition of 1.0 kg/t of hydrogen peroxide reduces the consumption of chlorine dioxide at the stages of the final bleaching of pulp to 2.7 kg/t.
