Based on the pulp refinery data on October 2020, the total average of lignin content in the digester was about 20.5%. This high amount of lignin during the pulping process was due to the non-uniformity mixing between white liquor and lignin. Therefore, the objective of this research was to simulate delignification process in digester with two inlets white liquor using CFD Ansys 19.2. The various NaOH concentrations (16%-22%) and operating temperatures (151oC-160oC) were also investigated. The simulation results using CFD Ansys Fluent 19.2 showed the optimum condition of the remaining lignin of 16.7% obtained at NaOH 14 gL-1 and the temperature of 151oC, which was lower than the actual data (20.7%) Data obtained from the simulation results can be used to analyze several aspects such as mass fraction of each compound, temperature distributions, velocity profile, and vector. CFD simulations can be used by researchers as a guide for experiment.
