Pulp Manufacture

The division consists of professionals who focus on the process of converting cellulosic raw materials into pulp including receiving, storing and processing raw materials as well as the mechanical and chemical purification of the pulp for its end use and the recovery of chemicals and by-products from the processes employed.

Displacement washing of softwood pulp cooked to various levels of residual lignin content, TAPPI Journal September 2021

ABSTRACT: This study investigates the influence of the degree of delignification of kraft spruce pulp cooked at seven different kappa numbers, ranging from 18.1 to 50.1, on the efficiency of displacement washing under laboratory conditions. Although the pulp bed is a polydispersive and heterogeneous system, the correlation dependence of the wash yield and bed efficiency on the Péclet number and the kappa number of the pulp showed that washing efficiency increased not only with an increasing Péclet number, but also with an increasing kappa number. The linear dependence between the mean residence time of the solute lignin in the bed and the space time, which reflects the residence time of the wash liquid in the pulp bed, was found for all levels of the kappa number. Washing also reduced the kappa number and the residual lignin content in the pulp fibers.
