Optimization of the Manufacture of Stearic Acid Based on Refined Bleached Deodorized Palm Stearin (RBDPS) According to Quality Standards

Introduction

Producing high-quality and stable stearic acid from raw materials such as Refined Bleached Deodorized Palm Stearin (RBDPS) is a significant challenge in the chemical industry. Stearic acid distillating (DAS) produced from RBDPS is often unstable and difficult to achieve quality standards. This is due to several factors, including low heat stability, low production levels, high levels of mild fraction and residue production, and the existence of impurities. In this study, we reveal the secret of the optimization of the Stearic Acid Distillation Process, which can produce products with stable quality and according to standards.

The Challenges of Stearic Acid Distillation

In commercial production, stearic acid distillating (DAS) produced from RBDPS is often unstable and difficult to achieve quality standards. This is caused by several factors, including:

Low Heat Stability

The watershed often experiences unexpected color changes even though produced with raw materials such as Hydrogenated splitted RBPS Fatty Acid (HSRBDPSFA), which is relatively the same. This indicates that the heat stability of the stearic acid is not optimal, leading to color changes and affecting the quality of the product.

Low Production Level

The average watershed production only reaches 85%, with the lower temperature of the main separator column reaching 213 ° C. This indicates that the production level of the stearic acid is not optimal, leading to a loss of valuable product.

High Level of Mild Fraction and Residue Production

This shows that the process of separation and purification is not optimal, leading to a high level of mild fraction and residue production. This not only affects the quality of the product but also leads to a loss of valuable raw materials.

The Existence of Impurities

Chemicals of impurities such as odor-causing substances, colors, double bonds, and short chain fatty acids, very sensitive to oxidation and temperature changes, thus affecting the stability of fatty acid colors. The existence of impurities in the stearic acid affects its quality and stability, making it difficult to achieve quality standards.

Optimization of the Distillation Process

To overcome the challenges of stearic acid distillation, we carried out an optimization study using the factorial experimental method 3 x 2 x 3, a fixed model with a test 2 times, and statistical process control (SPC). This study focuses on three independent variables, namely:

Iodine Number (IV) Bait

IV is an indicator of the number of double bonds in fatty acids. The iodine number of the feed affects the quality of the stearic acid produced.

Flow Velocity (F) Bait

The flow velocity of the bait affects the efficiency of the separation process. The flow velocity of the bait affects the quality of the stearic acid produced.

Temperature of the Lower Part of the Main Separator Column (B md)

This temperature affects the rate of evaporation and condensation of stearic acid. The temperature of the lower part of the main separator column affects the quality of the stearic acid produced.

Optimization Results

The optimization results show that these three factors have a significant effect on the stability of the color and quality of the watershed. The optimum condition of the distillation process is found in IV feeds 0.60 g/100 g, F Bait 6.0 tons/hour, and temperature B md 222 ° C. In this condition, the level of watershed production, residue, and distillate -2 obtained are 90.783%, 4.96%, and 2.54%. The resulting watershed has a stable quality with IV 0.175 g/100g and Heat Stability 0.6 R/5.45 Y, which meets the established quality standards and SPC stability criteria.

Conclusion

This discovery opens a new path for the chemical industry in producing high-quality and stable stearic acid from RBDPS. This simple and effective optimization method is a solution for the problems that have been faced in the process of distillation of stearic acid, and can be applied to industrial scale.

Future Directions

The optimization of the distillation process of stearic acid from RBDPS is a significant breakthrough in the chemical industry. This study provides a new approach to producing high-quality and stable stearic acid, which can be applied to industrial scale. Future studies can focus on the application of this optimization method to other types of fatty acids and the development of new technologies for the production of stearic acid.
