Displacement washing of spruce sulphite and kraft pulps was simulated using a laboratory washing cell. Geometrical properties of pulp fibres, as well as intrinsic properties of spent red and black liquors were determined. The sulphite spruce pulp beds showed the intrinsic permeability of 3.0 x 10(-12) to 6.7 x 10(-12) m(2) and the specific resistance of 1.2 x 10(9) to 2.3 x 10(9) m kg(-1), while, for the kraft spruce pulp, the former was within the limits of 1.2 x 10(-12) to 3.0 x 10(-12) m(2) and the latter within the limits of 2.6 x 10(9) to 6.3 x 10(9) m kg(-1). The displacement washing process was described by the washing curves measured for lignosulphonates and/or alkali lignin. The wash yield determined for sulphite spruce pulp was fo...
