Industrial Lo-Solids Pulp Digester Simulation by the Purdue Model
Source abstract
Abstract
The Purdue model was adapted to simulate an industrial Lo-Solids pulp digester using ad-hoc reac-tion kinetics for Pinus radiata cultivated in Chile. Simulation results for blow line kappa number, pulp yield, free liquor temperature profile, and pulp production rate all agreed well with pulp mill data from Celulosa Arauco y Constitucion’s Arauco plant in Chile. Researchers then applied the mathematical model to simulate an increase in fil-trate flow to the modified continuous cooking zone to save white liquor consumption, keeping blow kappa number at its target value. Simulation results show a 9.1% savings of white liquor and a significant decrease in dissolved sol-ids content, thus improving the Lo-Solids pulping process.
