Penurunan Silica Content Di Line 5-6 Woodyard Pt Rapp Untuk Dissolving Pulp

---

ABSTRACT
Silica content is an useless or unnecessary material contained in the chip where the
chip will later be sent to the customer (Fiberline) for dissolving pulp. Silica in the
chips produced, especially for dissolving pulp, is a concern, so it is necessary to
carry out a series of steps to reduce the silica content. Several factors that affect
silica content include the type of wood (bark on and debark) and wood storage
blocks (concrete and soil). In this final project, the observation title has been
determined, namely "Reduction of Silica Content in Woodyard Line 5-6 PT RAPP
for Dissolving Pulp". This observation aims to reduce the silica content of the chip,
especially dissolving pulp. The stages of the silica reduction process include
several areas of concern, including hauling trucks, wood storage blocks, Gentle
Feeds, Water Basin, and Roller Tables. Several areas of concern were made
significant changes so that the results of the silica content were more optimal. The
high and low silica content greatly affects the production process, the equipment
used, to the resulting product in the form of chips. The maximum silica content
target in 1 year is ≤ 180 ppm. Silica before the lowest decrease was 167.88 ppm in
July and after the lowest decrease was 150.70 ppm in December. Based on the
observations, it can be concluded that the more bark on wood that is processed into
chips, the lower the silica content. For wood storage blocks, the more wood hauled
in the concrete wood storage block, the lower the silica content in the process. The
stages of the silica reduction process need to be carried out periodically in order to
get optimal silica content results.
