eng	Displacement of Black Liquor from Kraft Pulp Bed by Solutions of Non-ionic Surfactants	In a laboratory washing cell, the displacement washing of unbleached kraft pulp was investigated. Distilled water and solutions of nonionic surfactants were used to displace black liquor from the pulp bed. Using the step function input change method, the washing breakthrough curves obtained experimentally were described by the axially dispersed plug flow model. To characterize the displacement washing process, the wash yield was evaluated. Results obtained for solutions of nonionic surfactants were compared with those for distilled water.
