An Influence of Pulp Consistency upon the Efficiency of Displacement Washing
Original language description
A mathematical model assuming an axial dispersion mechanism, based on two dimensionless criteria, namely the Péclet number and the Biot number, was proposed for displacement washing of packed bed of porous, compressible, and cylindrical particles. Bulk fluid concentration, intra-pore solute concentration, and concentration of the solute adsorbed onto the fiber surface were considered as a function of the washing time and of position in the bed. Displacement washing experiments performed on pulp beds formed from unbeaten, unbleached kraft fibers were simulated with a laboratory washing cell. The model predicted values of the breakthrough curves, the average alkali lignin concentration in the bed, and the displacement ratio were compared with those obtained experimentally. A close agreement was found between experimental data and ones calculated from model equations.
