Feb 27, 2025 by ADMIN 74 views

Introduction

Glycerol is a by-product of the biodiesel production process, often overlooked due to its impurities, such as water, methanol, KOH, and other compounds that reduce its quality. Without proper purification, this glycerol cannot be utilized optimally. Recent research has been conducted to improve this glycerol condition by using three types of organic acids, namely vinegar acid, formic acid, and benzoic acid. In this study, each treatment was carried out three replications to ensure accurate results. The main purpose is to obtain data on glycerol content, water content, density, and pH values that have been purified.

Glycerol is a valuable by-product that can be utilized in various industries, including food, cosmetics, and pharmacy. However, its impurities make it difficult to use optimally. The use of organic acids in the purification of glycerol not only eliminates impurities but also increases the economic value of glycerol itself. Clean glycerol can be utilized in various industries, including food, cosmetics, and pharmacy. Thus, this research not only provides practical benefits but also contributes to increasing efficiency in the use of biodiesel by-product resources.

Purification of Glycerol using Organic Acids

The purification of glycerol is done through an acidification process with a ratio of acid volume to the volume of glycerol of 3:10. The results showed that the use of formic acid produced the highest glycerol content, which was 72.39%, with a moisture content of 23.57%, glycerol density of 1.16 g/ml, and pH that reached neutral value 7. Interestingly, this purification process produces two layers, where the upper layer consists of fatty acids, while the lower layer is purer glycerol.

The use of formic acid in the purification of glycerol is a relatively easily accessible acid and has a high effectiveness in purification. The results showing the water content of 23.57% also described the importance of the dehydration process in the purification of glycerol. Excess water can interfere with the use of glycerol in product formulations, so it is important to control the water content in the final product.

Benefits of Glycerol Purification using Organic Acids

The use of organic acids in the purification of glycerol not only eliminates impurities but also increases the economic value of glycerol itself. Clean glycerol can be utilized in various industries, including food, cosmetics, and pharmacy. Thus, this research not only provides practical benefits but also contributes to increasing efficiency in the use of biodiesel by-product resources.

In terms of the environment, the purification of this glycerol underlines the opportunity to reduce waste from the biodiesel process, while optimizing the use of existing raw materials. With the increasing demand for environmentally friendly products, this kind of research can open the way for innovation in processing techniques and increase the sustainability of the biodiesel industry as a whole.

Conclusion

The purification of the biodiesel by-product of glycerol using organic acids is an important step that not only improves the quality of glycerol but also adds to added value to the industry. Further efforts in research and development of purification techniques will be very useful in optimizing the use of glycerol and reducing the environmental impact of the biodiesel industry waste.
