“Pengaruh P-Factor Terhadap Viskositas Pre O2 Pada Pemasakan Dissolving Pulp Di Unit Digester Fiberline #1.”

ABSTRACT
Dissolving pulp is pulp that is used as raw material for rayon with certain
characteristics such as having high purity such as high cellulose content (>94%),
and low content of hemicellulose, lignin, and extractives. According to Alaudin
(1982), the manufacture of rayon pulp with the sulfate process alone cannot
produce pure pulp as desired, because some hemicellulose becomes resistant to
alkaline reactions so that it will remain in the fiber. This difficulty can be overcome
by processing wood chips through the Prehydrolysis process before cooking with
sulfate. Variables that affect Prehydrolysis are temperature and time. The increase
in Prehydrolysis time and Prehydrolysis temperature will also affect the quality of
the pulp produced. Therefore, this study aims to determine the appropriate range
of P-factors to produce the desired viscosity of Pre O2 dissolving pulp and
determine the magnitude/value of the influence of the parameters at the cooking
stage on the viscosity of the resulting dissolving pulp. Viscosity is a measure that
states the viscosity of a liquid or fluid to flow at a resistance and is measured at a
certain temperature. The purpose of this viscosity determination is to show the level
of cellulose degradation (degradation) due to flake processing. The desired
viscosity after this cooking process is 750 dm3/kg. Observations showed that the Pfactor
with a range of about 650 - 700 can produce a viscosity of 759 - 804 dm3/kg.
Then from the results of the study, P-factor has an effect of 25.45%, AA charge has
an effect of 23.91%, H-factor has an effect of 18.12%, EA hot black liquor has an
effect of 12.61%, Hot liquor filling volume has an effect of 10.85% , and WL
Sulphidity has an effect of 9.06%.
