Abstract :

The delignification process in the study, obtained standard Kappa (lignin) pulp levels (19–22) based on production data on 2 September 2019 which approached a maximum capacity of 4220.6 ADT / D, at a pulp mill that had a tank capacity of 5140 m³ and high 68,295 m2 by optimizing White Liquor (NaOH) dosages of 18, 19, 20, 21, 22 g / l and temperatures 141, 142, 143, 144, 145 0C based on the control parameters of the pulp mill cooking control. The research modeled using CFD Ansys Fluent 19.2 can compare actual field data which analyzes the expected lignin results at compatible NaOH concentrations and temperatures. In addition, from the research obtained the Contour of Lignin Mass, NaOH, Na–Lignate, H2O, Reaction Kinetics Rate, Density Contour and Mass Fraction of Reactants and Products Against Digester Height.
