Washing of soda pulp cooked from rapeseed straw

Popis výsledku v původním jazyce

Displacement washing process was described by displacement washing curves recorded for alkali lignin like a tracer. Mathematical treatment of the washing curves, which were obtained as a response to the step input signal, gave the dimensionless number known as the Péclet number characterizing the displacement of lignin from the pulp pad. For detailed description of displacement washing process, further parameters, such as the traditional wash yield, as well as axial dispersion coefficient, were also evaluated. The preliminary results obtained showed that, similarly as for kraft softwood and hardwood fibres, the wash yield determined for soda rapeseed pulp was found to be lower than that for non-porous incompressible particles. Comparing our results forsoda pulp with those reported for softwood and hardwood pulps earlier, the displacement front becomes irregular owing to the heterogeneity of soda pulp fibre bed having much greater hydraulic resistance. With respect to this fact, the gr
