Abstract

Continuou Settling Tank (CST) is one of the units located at the clarification station where the CST works to separate oil and mud based on differences in specific gravity where the lighter density will go up, namely oil, while the heavy type will settle to the bottom, namely mud. The language here is how to make the construction of the agitator transmission in the Continuou Settling Tank (CST) unit and how the agitator blade influences the oil content contained in the sludge in the Continuou Settling Tank (CST) unit. The method is carried out with variations in the number of blades that open 2, 4 and 6 pieces. The specifications of the equipment data obtained are primary data resulting from the design of the Continuou Settling Tank (CST) tool. Based on the blade obtained two results the percentage of oil content of 10.85%. This shows that there is still oil content in the mud. Likewise, the blade that found four pieces was 8.678%. While on the blade that got six pieces, the average percentage of oil was 7.652%. This shows that the blades that have been opened six pieces have met the desired percentage of oil standards.

Abstract

PT XYZ Belawan has a kernel crushing plant unit that produces Crude Palm Kernel Oil (CPKO) with 700 tons/day capacity. Palm kernel processing is carried out in two pressing stages. The first stage or first press produces oil and cake, while the second stage or second press produces oil and meal. The meal still contains 7-8% of the oil content. This study is aimed to determine the amount of CPKO yield, oil content, and oil losses in a meal during the pressing palm kernel process. The method used was the calculation of the mass balance in each process flow. The mass balance calculation is carried out after collecting the secondary data from the factory, including the analysis of water content, solids, FFA, and oil content. Based on the calculation results, CPKO yield was 48.10% of the average kernel mass rate of 714.7155 tons and met the plant standard of at least 44%. Furthermore, the average yield of oil content from the meal was 7.45% and oil losses were 3.86%.
