Abstract

This research was conducted at PT. XYZ. Oil losses are the percentage of oil that is absent or not included in the subsequent oil processing process but is included in the waste process. The aim of this research is to determine the percentage of oil loss contained in press dregs using the soxhletation extraction method. Based on the results of mass balance calculations, it was obtained that the number of components entering the screw press was 22,401 kg/hour of digester chopping and 6000 kg/hour of delusion water. The number of components coming out of the Screw press, namely press dregs, is 8,400 kg/hour and Delution crude oil is 20,001 kg/hour. The results of this research show that the oil losses obtained during the pressing process were 4.45% or 373.80 kg/hour. This is in accordance with factory standards where oil losses are 4-6%.

Abstract

In the industry, the use of a Thermal Oil Heater (TOH) is employed to generate a heating system by heating oil, which will be used in the production process in units that require a heating system. In the TOH unit, a pump is used to transfer the fluid, where the pump's connection uses a flange coupling to link the motor and magnetic pump for transferring thermal oil. The size and material of the bolts and nuts in the flange coupling are crucial to ensure operational safety and efficiency, taking into account rotation, power, and thermal expansion. Through observation, documentation, interviews, and literature studies, the research shows that the optimal nominal bolt diameter is 9.52 mm with a coupling distance of 60 mm, in accordance with industry standards such as the American National Standards Institute (ANSI), the International Organization for Standardization (ISO), and the Japan International Standard (JIS) to prevent joint failure and damage to the flange coupling
