摘要
Industrial oxygen delignification is modelled by taking into account oxygen mass transfer, pulp delignification kinetics and mixer performance. The efficiency of delignification is calculated as function of NaOH charge, oxygen charge and pressure, consistency and temperature. The simulation is tested by comparing the predictions to actual mill operation of a two-stage oxygen delignification system at Irving Pulp and Paper, Saint John, NB, for softwood kraft pulp.
