Abstract

Two major operational problems in pulp mills are relatively low pulp yield and high levels of rejects. Conversion of some rejects into accepts can increase pulp yield without sacrificing pulp quality. To improve this conversion, the penetration and diffusion of cooking liquor into the wood chips was enhanced by adding a surface-active material to the cooking liquor. This paper details the effect of a blend of surfactants on cooking liquor penetration and diffusion. Field experience with this surfactant-based digester additive is discussed, and economic and environmental impacts are highlighted.
