Abstract:
Abstract The objective of the pulp washing is to remove the soluble undesired products i.e. black liquor containing organic solids (lignin), inorganic solids (Na, Mg, Ca and K ions). Removal of these undesired products reduces the consumption of chemicals in subsequent sections, which in turn produce less pollutant. Ideally pulp should be washed using less amount of wash water and with maximum removal of black liquor solids. To fulfill the aforesaid objective, the numerical solutions are obtained of the displacement washing model for multistage in counter current manner and study the effect of various parameters on multistage washing. For the numerical solution “pdepe” solver in MATLAB is applied on the axial domain of the system of governing partial differential equations. Keywords: MATLAB: “pdepe”solver; Pulp washing model; Peclet number; kappa number; porosity Multistage, Counter current
