ABSTRACT Acrylonitrile is a clear, colorless liquid with a slightly pungent odor. It is used as a chemical intermediate in the production of acrylic fibers, plastics, synthetic rubber, and numerous other products. The fluidized bed manufacturing process for acrylonitrile was developed by scientists at The Standard Oil Company (SOHIO). To meet the demand for acrylonitrile, a production plant wi…
ABSTRACT Recovery boiler is a piece of equipment used in the pulp and paper industry that has two functions: recovering chemicals contained in black liquor for reuse in the cooking process and generating energy. Several components of a recovery boiler are very important for improving energy efficiency, one of which is a direct heater. The direct heater in a recovery boiler is used to heat blac…
ABSTRACT Magnesium sulfate (MgSO₄) has been proposed as an effective and economical alternative to chelating agents such as DTPA (Diethylene Triamine Pentaacetic Acid) in bleaching processes, particularly in the hydrogen peroxide (H₂O₂) bleaching method. MgSO₄ serves as a source of magnesium ions (Mg²⁺), which can compete with catalytic metal ions to bind to H₂O₂ or fiber surfac…

This study aims to analyze the Steam Economy value in the evaporator unit at PT Tanjungenim Lestari Pulp and Paper to evaluate the efficiency of steam energy utilization. Th…
ABSTRACT The baling line is the final stage of the process in the Pulp Dryer. At this stage, bales are packed into 1 unit with a weight of 2020 ± 9kg per unit and a height of 168 cm – 170 cm. The baling line often experiences downtime, which results in lost production time. This observation was conducted with the aim of minimizing downtime of the tying machine in the baling line of Pulp Dry…
ABSTRACT Filters are important components in oxygen production systems, especially in the pulp and paper industry, because they play a role in maintaining gas purity and the stability of the production process. This study aims to analyze the efficiency of primary and secondary filter usage and the effect of differential pressure on oxygen production capacity, by considering maximum capacit…
ABSTRACT One of the important parameters in the cooking process is the liquor to wood ratio (L/W ratio) which is the ratio between the volume of cooking liquid and the mass of wood used. An imbalance in the material balance in the impbin & digester unit can cause problems such as excess chemical liquor for the cooking process, chips that do not cook evenly. In this research, the focus is o…
