Faktor-Faktor Yang Memengaruhi Kappa Reduction Fiberline #1 (Dissolving Pulp)

ABSTRACT Oxygen Delignification (ODL) aims to reduce the Kappa number after the cooking process in the Digester. The kappa number is defined as the percentage of lignin left in the pulp. In the Fiberline 1 ODL stage, the Kappa Number was reduced from 1,764% to 0.735% lignin. The decrease in Kappa Number occurs in the O2 reactor by using O2 chemicals to degrade lignin and Alkali to create a…
