Optimizing Oxygen Level Control in Thermal Deaerators: A Study at the Murini Palm Oil Mill Sam-i

The Murini Palm Oil Mill Sam-i in Duri, Riau, is a significant player in the palm oil industry. However, maintaining the efficiency and longevity of its equipment is crucial to its success. One of the key factors that can affect the performance of the mill's equipment is the level of oxygen in the water used in the thermal deaerator. Thermal deaerators are devices that eliminate dissolved oxygen in water, which can cause corrosion in factory equipment. This study focuses on the system of controlling oxygen levels in water in thermal deaerators at the Murini Sam-i palm oil mill.

Thermal deaerators are an essential component of many industrial processes, including the palm oil industry. They work by heating the water to a high temperature, which causes the dissolved oxygen to be released from the water. However, if the oxygen level in the water is not properly controlled, it can lead to corrosion in the equipment, which can result in costly repairs and downtime. Corrosion is a major concern in the palm oil industry, as it can lead to equipment failure, contamination of the product, and even safety hazards.

This study employed two control methods to regulate the temperature and pressure in the thermal deaerator: the proportional-integral (PI) method and the Routh-Hurwitz method. The PI method is a widely used control method in industry due to its ease of implementation and relatively stable results. The Routh-Hurwitz method, on the other hand, is a more complex method used to analyze system stability.

The results of this study showed that the optimal KC (proportional gain) value obtained by the PI method was 0.4, and the Pb (Integral Time) was 250%. These results indicate that the PI method gives more stable results compared to other methods. The Routh-Hurwitz method, which is used to analyze system stability, showed a positive value, indicating that the control system is stable.

The results of this study have important implications for the optimization of oxygen level control in thermal deaerators. The PI method, which is widely used in industry, was found to be effective in regulating the temperature and pressure in the thermal deaerator. The Routh-Hurwitz method, which is used to analyze system stability, also showed that the control system is stable.

This study made an important contribution to understanding and optimizing the oxygen level control system in thermal deaerators. The results of this study can be used to improve the efficiency and use of equipment in oil palm factories, as well as minimize the negative impact of corrosion. In addition, this research opens opportunities for the development of a more sophisticated and effective control system in the future.

Based on the results of this study, the following recommendations are made:

The PI method should be used as the primary control method for regulating the temperature and pressure in the thermal deaerator.
The Routh-Hurwitz method should be used to analyze system stability and ensure that the control system is stable.
Further research should be conducted to develop a more sophisticated and effective control system for thermal deaerators.

This study has several limitations, including:

The study was conducted on a single thermal deaerator, and the results may not be generalizable to other deaerators.
The study only examined two control methods, and other methods may be more effective in certain situations.
The study did not examine the impact of other factors, such as water quality and equipment design, on the performance of the thermal deaerator.

This study opens opportunities for further research in the area of oxygen level control in thermal deaerators. Some potential research directions include:

Developing more sophisticated and effective control systems for thermal deaerators.
Examining the impact of other factors, such as water quality and equipment design, on the performance of the thermal deaerator.
Conducting further research on the PI method and the Routh-Hurwitz method to improve their effectiveness and efficiency.

In conclusion, this study has made an important contribution to understanding and optimizing the oxygen level control system in thermal deaerators. The results of this study can be used to improve the efficiency and use of equipment in oil palm factories, as well as minimize the negative impact of corrosion. Further research is needed to develop a more sophisticated and effective control system for thermal deaerators.
