Displacement of Black Liquor From Pulp Bed
Original language description
Brownstock washing was simulated using a laboratory displacement washing cell. The displacement of black liquor from the kraft pulp bed was described by the dispersion flow model containing one dimensionless parameter, the Peclet number, for alkali lignin, and sodium as the tracers. To characterize washing operation, the traditional wash yield, dispersion coefficient, mean residence time of both solutes, as well as the holding time of wash liquid were evaluated. With respect to various size of lignin fragmented in black liquor and sodium ions, the rate of leaching from within the fibres is different for both solutes. Therefore, the displacement washing efficiency should be expressed not only by the traditional wash yield, but also the amounts of both solutes washed out at the wash liquor ratio equal to unity, as well as total amounts removed during washing operation must be taken into account. Various ability of both solutes to their displacement from the labyrinth of pores in the pulp
