Abstract

The delignication 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 eld 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.
