Abstract

Deodorization is a crucial stage in palm oil refining aimed at removing components that cause odor and flavor, such as free fatty acids (FFA) and peroxides. This process utilizes high temperatures and vacuum pressure in a prestripper machine. The study evaluates the impact of temperature and vacuum pressure on the quality of the resulting oil. Findings indicate that the optimal temperature for deodorization is approximately 267°C with a vacuum pressure of 2.8 mbar, effectively reducing FFA levels below 0.1% and improving oil color. Excessive temperatures or inadequate vacuum pressure can increase FFA levels and darken the oil, thereby compromising product quality. Precise control of operational conditions during the deodorization process is essential for ensuring palm oil meets industry quality standards, reducing energy waste, and enhancing production efficiency. In conclusion, accurate regulation of temperature and vacuum pressure is vital for consistently producing high-quality oil.

Abstract

The sterilization process in the boiling of fresh fruit bunches (FFB) of oil palm is a critical stage in crude palm oil (CPO) production. The primary goals of this process are to soften the bunches, deactivate destructive enzymes, and facilitate the separation of the fruitlets from the bunch. However, deviations in pressure and boiling duration from the standard can lead to oil losses, where oil is carried away by the condensate. This study analyzes the impact of pressure and boiling conditions on oil losses during the three peaks of sterilization. Results indicate that increased pressure above the standard, particularly during the first and second peaks, significantly contributes to higher oil losses. Additional factors influencing these losses include the physical condition of the fruit, steam pressure fluctuations, and the quality and stability of the steam used. At the third peak, despite reaching a pressure of 2.8 bar, technical issues such as sterilizer leaks and unstable steam supply also led to variations in oil losses. In conclusion, minimizing oil losses requires strict control over pressure, the physical condition of the fruit, and steam quality during the sterilization process.

Abstract

Crude Palm Oil (CPO) is a vegetable oil extracted from the mesocarp or flesh of the oil palm fruit after several processes of oil and kernel separation. One of the key steps in CPO processing is the oil purification stage at the clarification station, where an essential piece of equipment used is the Oil Purifier. During this stage, the purification process is crucial because if the oil still contains impurities or a high amount of water, it can degrade the quality of the oil. Therefore, the Oil Purifier must be carefully managed in the CPO processing because this process involves separating oil, water, and impurities before the oil is pumped to the vacuum dryer. If the purifier does not function properly, it can negatively affect the quality of the oil produced. Hence, a reassessment of the Oil Purifier in the Clarification Unit is necessary. The procedure for analyzing the samples involves assessing the moisture and impurity content in AOP (After Oil Purifier) and BOP (Before Oil Purifier) samples. The results indicate that the feed temperature significantly affects the moisture content in the Oil Purifier's output. Additionally, the feed flow rate also has a substantial impact on the moisture content in the Oil Purifier's output, where the moisture content of the oil from the purifier is related to the moisture content of the feed oil entering the purifier.

Abstract

Crude Palm Oil (CPO) is a vegetable oil derived from the fruit of the oil palm plant. During the processing of palm fruit into CPO, sludge is produced as a byproduct of the oil purification process. This sludge is reprocessed in a sludge centrifuge because it still contains oil, with hot water added as a diluent to facilitate the separation between sludge and oil. The addition of hot water helps maintain the balance in separating sludge and oil. Low water content will cause the incoming feed to become thicker, making it difficult to separate the oil in the sludge centrifuge. The sludge centrifuge separates the oil in the sludge using centrifugal force. To date, the company has been adding hot water at a rate of 1.5 tons per hour, resulting in oil losses in the heavy phase ranging from 0.9% to 1%. Due to the high oil content in the sludge, a study is needed to evaluate the performance of the sludge centrifuge in processing the sludge to ensure that oil losses in the heavy phase meet company standards. The method used to analyze oil losses is extraction. The results show that increasing the amount of hot water reduces the percentage of oil losses. Additionally, the optimal oil loss percentage occurs at a hot water addition of 3 tons/hour.

Abstract

This study evaluates the efficiency of the Takuma N750 water tube Boiler at a palm oil mill, which has a maximum evaporation capacity of 27 tons per hour. Boiler efficiency is crucial for converting thermal energy from fuel into steam, with operational data showing significant efficiency variations. The average efficiency was 54.34%, substantially below the target of 80%, with the highest recorded efficiency at 60.4% and the lowest at 51.08%. The analysis revealed an inverse relationship between excess air and Boiler efficiency; as excess air increases, efficiency decreases. For instance, with 139.22% excess air, efficiency dropped to 56.36%, compared to 60.4% with 123.44% excess air. The study concludes that optimizing excess air levels is essential for improving Boiler efficiency, recommending adjustments to combustion parameters and excess air control to enhance performance and reduce operational costs. This research offers insights into better Boiler operation and energy management in palm oil mills.

Abstract

One of the companies operating in the palm oil processing industry uses steam as a heating medium in its process equipment. There is an energy-saving initiative in place that involves recovering steam condensate to heat warm water through a Plate Heat Exchanger (PHE) unit. The heat exchange in the PHE occurs in a counter-current manner with a target water temperature of 40°C (set point). The heating process is conducted in a circulation loop where the steam condensate enters the PHE to heat the warm water, and the output is then returned to the condensate storage tank before re-entering the PHE. This study analyzes the energy recovery process of the heat contained in the condensate for heating purposes. Based on observations, the steam condensate can raise the water temperature to the set point. However, using condensate for water heating takes longer compared to using steam. Additionally, in terms of quantity, a higher condensate flow rate is required compared to steam heating. Utilizing steam condensate as a heat source can reduce steam consumption, thereby lowering production costs at the PKO plant.

Abstract

Currently, many charcoal makers use drums as pyrolyzers, this is because the oxygen (O2) entering the combustion chamber is controlled, the oxygen level entering the combustion chamber must be low so that the shell does not burn out. The aim of this research is to calculate the heat loss rate of the pyrolyzer for making coconut shell charcoal and to analyze the effect of a mixture of clay, sand and rice straw insulator on the charcoal yield and quality of the charcoal produced. This research focuses on reviewing pyrolyzer modifications based on aspects of mixed variations of clay, sand and rice straw insulating materials in dealing with heat loss. Testing of furnace performance is carried out using comparisons of several parameters or components including temperature, time and insulator material. The final stage of the research is to draw conclusions and draw conclusions based on the results of material variations and the factors that influence them. The research results show that the best insulator is the TP3 pyrolyzer with an insulator mixed with clay, sand and rice straw in a ratio of 2:1:0.3 with a heat loss of 7,378.992 W and ΔT of 195°C. The addition of rice straw to a mixture of clay and sand insulators provides significant benefits in increasing ΔT and reducing heat loss. The addition of rice straw to a mixture of clay and sand insulators has a significant impact on the carbonization process of coconut shell charcoal. Even though the charcoal yield decreases with the addition of rice straw to the insulator, the quality of the charcoal produced increases, especially in terms of fixed carbon content with the best insulator being the TP3 pyrolyzer with a carbon content value of 78.54%.
