8. Interfacing spectrophotometry to process liquors applications to kraft pulping
Abstract : This thesis summarizes the outcome of work performed withthe objective to contribute to the knowledge and development ofthe kraft cooking process using spectrophotometricinterfaces.In kraft cooking, it is desirable to maximize the removal oflignin in the cook without loss of pulp strength.

9. Inorganic ions in wood chips- Leaching prior to Kraft pulping and effect of calcium on Kraft delignification
Abstract : Wood is the main source of Non-Process Elements (NPEs), such as, calcium, potassium, manganese and chloride in Kraft pulp mills. Due to the recirculation of cooking chemicals and water, process disturbances related to the accumulation of NPEs in the process streams are inevitable. READ MORE

10. On the Interrelation Between Kraft Cooking Conditions and Pulp Composition
Abstract : In the early 1990’s, a lot of work was focused on extending the kraft cook to a low lignin content (low kappa number). The driving force was the need to further reduce the environmental impact of the bleaching, as less delignification work would be needed there. READ MORE
