Analisis Active Alkali Charge Terhadap Yield Pada Kraft Pulp A Model Fiberline #2

ABSTRACT
Active alkali charge is the combined concentration of sodium hydroxide (NaOH) and sodium sulfide (Na2S) solutions in white liquor. The active alkaline charge in white liquor is useful for degrading lignin and other compounds (extractive) in wood and dissolving simple sugar groups that are still united in the pulp. This study aims to determine the effect of active alkaline charge on yield, kappa number, and viscosity, the effect of H-factor on active alkali charge, and the effect of white liquor strength on kappa number. This research was conducted by collecting secondary data from kraft pulp production operations in the digester. After performing data processing and analysis on the digester during kraft pulp production, it was found that the active alkali charge correlated with yield, kappa number, and viscosity with R2 values of 0.9485, 0.9367, and 0.9371, respectively. The influence of the H-factor on the active alkaline charge was found to be correlated with the R2 value of 0.9044. The effect of white liquor strength on the kappa number was found to be correlated with the R2 value of 0.9434. The active alkali charge value influences the percent yield; the more optimal the active alkaline charge value is, the higher the yield will be. Increasing or decreasing the active alkaline charge used also affects the increase or decrease in the kappa number and viscosity. The higher the H-factor used, the lower the level of active alkali required; the stronger the white liquor strength, the more alkali available to interact with lignin, and the lower the kappa number.
Keywords: active alkali charge, yield, kappa number, viscosity, H-factor
