Pengaruh % Charge Klorin Dioksida (Clo2) terhadap Penurunan Bilangan Kappa dari Proses Unbleach Blending Ke Proses Bleaching D0 Stage di Pt. Toba Pulp Lestari, Tbk Porsea

Abstract

Kappa number is one of quality parameters in pulp industry. Kappa number is used to measure the degree of pulp delignification in bleaching plant. By making the variations of % charge chlorine dioxide (ClO2) in stage one of bleaching plant, it will obtained by varying kappa numbers. Kappa number analysis is done by titrimetric using oxidation – reduction methods. From the analysis, the greater the % charge chlorine dioxide (ClO2) in bleaching plant, kappa number will be more small.
