dc.description.abstractEnvironmental concerns and cost reduction have been the focus of pretreatment and extended delignification in Kraft pulping for some time now. Previous work has looked at the diffusion of tritiated water into softwood chips. This thesis looks at the diffusion of Na2S into southern pine softwood chips. Two size fractions were used. The measured diffusion data were compared to the equilibrium of mixing between the HS ion and water alone. Since pine is porous, effective diffusivities were calculated for each size fraction using a 1-dimensional model. Tortuosities were then calculated for the HS / pine wood system. These diffusivities are compared to values previously obtained for tritiated water.en_US
