Abstract

The studies of pulping technology help the pulp maker to have desired properties, from which one can make the paper grades with desired end-use properties. Recently there is more tend for having lower KAPPA NUMBER in order to use lower chemical in the bleaching unit and reduce environmental pollutions. This is a research of KRAFT COOKing, with Eucalyptus camaldulensis wood at the different EFFECTIVE ALKALI charge and the same cooking time- temperature and liquor to wood ratio for all. Objective of study was to investigate the effect of EFFECTIVE ALKALI charges on yield- KAPPA NUMBER- rejects and residual alkali that is one of the cooking variables. Current trend toward lower KAPPA NUMBER is interest in modified pulping. This study discusses the changes needed in cooking variable in order to make a modification on KRAFT COOK. The results showed that changes in EA concentration significantly affected on yield and KAPPA NUMBER. The decreased KAPPA NUMBER provided a pulp with lower screen rejects. In this research- it was found the higher EA concentration affected in the KRAFT COOK In order to improve that with the lower KAPPA NUMBER and desire PULP YIELD.
