Improvement of the Ability of Scent Bleaching Earth Gowers in the Crude Palm Oil Clerk Using the Desorption Method with Microwave Assisted Extraction and Acid Activation

Introduction

The palm oil industry is one of the largest contributors to the global production of vegetable oils, with millions of tons of crude palm oil (CPO) being produced every year. However, the process of purifying CPO is often carried out with the help of adsorbents, including bleaching earth, which can cause new problems, such as the resulting waste, known as Spent Bleaching Earth (SBE). This waste still contains 20-40% oil, so its management needs to be done carefully. One solution to utilize SBE is to regenerate, so that SBE can be used again as an adsorbent. This study aims to determine the effect of contact time and microwave power on decorpted desorbats, as well as to understand the existing kinetic model approach. Furthermore, this study will also explore the application of Regenerated Bleaching Earth (RBE) to the CPO adsorption.

The Problem of Spent Bleaching Earth (SBE)

Spent Bleaching Earth (SBE) is a waste product that is generated during the process of purifying CPO. This waste still contains 20-40% oil, which makes it difficult to manage. If not disposed of properly, SBE can cause environmental problems, such as soil and water pollution. Therefore, it is essential to find a solution to utilize SBE, so that it can be used again as an adsorbent.

The Solution: Regeneration of SBE

One solution to utilize SBE is to regenerate it, so that it can be used again as an adsorbent. This study aims to determine the effect of contact time and microwave power on decorpted desorbats, as well as to understand the existing kinetic model approach. Furthermore, this study will also explore the application of Regenerated Bleaching Earth (RBE) to the CPO adsorption.

Methodology

This study was conducted in three stages, namely the desorption stage using the Microwave Assisted Extraction (MAE) method, the acid activation stage, and the CPO adsorption stage using RBE. The desorption process is carried out with hexane solvents and contact time variations of 10, 20, 30, 40, 50, and 60 minutes, as well as microwave power variations of 180, 300, and 450 watts. After that, the acid activation stage is carried out using sulfuric acid. Analysis conducted includes SEM-EDXS, BJH Bet Analysis, and Color Testing, Free Fatty Acids, and Peroxide Numbers.

Results

Based on the results of the desorption stage, the best extraction conditions were obtained at a contact time of 40 minutes and the microwave power of 450 watts, which produced the highest number of desorbits, which was 17.33% of the total adsorbent. Analysis of SEM-EDXS and BET BJH shows that the SBE regeneration process and acid activation treatment give good results, so that RBE can be used again as an adsorbent.

Discussion

The results of this study show that the desorption process using the MAE method is effective in increasing the efficiency of desorption. The use of microwaves in extraction helps speed up the process of separating oil components from SBE by utilizing micro waves to heat the solvent. This results in a better penetration of solvents into the SBE structure, thereby increasing the extraction rate.

Acid activation using sulfuric acid is an important step to improve the ability of RBE adsorption. This treatment changes the physical and chemical properties of the adsorbent surface, making it more reactive to the oil components in the crude palm oil. With the results obtained, RBE is not only able to function as an effective adsorbent, but also provides economic benefits for the palm oil processing industry by reducing the cost of purchasing new adsorbents.

Conclusion

The entire integrated process shows that waste re-utilization technology not only provides solutions to waste problems, but also contributes to overall industrial efficiency. Through research and application of innovative methods, we can move towards a more sustainable industry, especially in the palm oil processing sector.

Recommendations

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

  1. The use of MAE method for desorption of SBE is recommended, as it is effective in increasing the efficiency of desorption.
  2. The use of acid activation using sulfuric acid is recommended, as it improves the ability of RBE adsorption.
  3. Further research is needed to explore the application of RBE to other industries, such as the food and pharmaceutical industries.

Future Research Directions

Future research directions include:

  1. Exploring the application of RBE to other industries, such as the food and pharmaceutical industries.
  2. Investigating the effect of different types of acid on the ability of RBE adsorption.
  3. Developing new methods for the regeneration of SBE.

Limitations of the Study

The limitations of this study include:

  1. The study was conducted on a small scale, and further research is needed to confirm the results on a larger scale.
  2. The study only explored the application of RBE to the CPO adsorption, and further research is needed to explore its application to other industries.

Conclusion

In conclusion, this study has shown that the desorption process using the MAE method is effective in increasing the efficiency of desorption, and that acid activation using sulfuric acid improves the ability of RBE adsorption. The results of this study provide a new perspective on the utilization of SBE, and highlight the potential of waste re-utilization technology in contributing to overall industrial efficiency.
