Displacement washing of soda pulp from rapeseed straw
Original language description
The aim of this work was to investigate the displacement washing process of soda pulp cooked from rapeseed straw. The displacement washing process was described by displacement washing curves recorded for alkali lignin like a tracer. The shape of the washing curves obtained experimentally indicated that the displacement of black liquor was non-ideal, i. e., it was between the ideal limits of plug flow and perfectly mixed flow. Mathematical treatment of the washing curves, which were obtained as a response to the step input signal, gave a dimensionless number known as the Péclet number characterizing the displacement of alkali lignin from the pulp pad. For detailed description of displacement washing process, further parameters, such as the traditionalwash yield, as well as axial dispersion coefficient, were also evaluated. The preliminary results obtained showed that the differences in intrinsic properties between soda rapeseed and kraft wood fibres have an impact on the displacement
