Study of Analysis of the Effect of the Number of Distillation Column on Methanol Purity at PT. Kaltim Methanol Industri Bontang, East Kalimantan
Introduction
The production of methanol is a complex process that involves various stages, including distillation, to produce high-quality products. One of the critical factors that affect the purity of methanol is the number of distillation columns used in the process. In this study, we conducted an analysis of the effect of the number of distillation columns on methanol purity based on various parameters, including TMA (trimethylamine), acetone, ethanol, acidity, and water content. The study was conducted at PT. Kaltim Methanol Industri Bontang, East Kalimantan, a leading methanol producer in the region.
Background
Methanol is a widely used chemical in various industries, including the production of formaldehyde, acetic acid, and methyl tertiary butyl ether (MTBE). The purity of methanol is critical in ensuring the quality of the final product. However, the production of methanol is often affected by various impurities, including TMA, acetone, ethanol, acidity, and water content. These impurities can be present in the raw materials used in the production process or can be generated during the production process itself.
Methodology
The methodology used in this study follows the IMPCA (International Methanol Producers and Consumers Association) standards that were revised in 2010. The analysis of TMA, acetone, and ethanol was conducted using the gas chromatography method, while the acidity analysis was conducted using the acidimetry titration method. The analysis of water content was conducted using the Karl Fischer method. The results of the analysis were used to calculate the level of pollutants in the output of each distillation column and the methanol purity after passing through the distillation process.
Analysis Method
The analysis method used in this study is based on the following steps:
- Sample collection: Samples were collected from the raw methanol tank, lower preun column, F07 column over pressure, and the top column of the atmosphere.
- Analysis of TMA, acetone, and ethanol: The gas chromatography method was used to analyze the levels of TMA, acetone, and ethanol in the samples.
- Acidity analysis: The acidimetry titration method was used to analyze the acidity levels in the samples.
- Water content analysis: The Karl Fischer method was used to analyze the water content levels in the samples.
- Calculation of methanol purity: The results of the analysis were used to calculate the level of pollutants in the output of each distillation column and the methanol purity after passing through the distillation process.
Results and Discussion
The results of the analysis are presented in the following table:
| Column | TMA (ppb) | Acetone (ppm) | Ethanol (ppm) | Acidity (%) | Water content (ppm) | Methanol purity (%) |
|---|---|---|---|---|---|---|
| Raw methanol tank | 2478.8 | 6186.53 | 480,626.7 | 13.8667 | 274 | 90.63 |
| Lower preun column | 549.9267 | 3102.3 | 479.86 | 12.91867 | 262 | 96.235 |
| F07 column over pressure | 1263 | 2928.3 | 4158 | 0.0110367 | 23 | 99.9097 |
| Top column of the atmosphere | 0.0489 | 0.67 | 1615 | 0.01725 | 23533 | 99.93 |
From the results, it appears that the number of distillation columns has a significant effect on methanol purity. Each column has a specific function in separating methanol from various impurities, thereby increasing the level of purity of the final product.
Conclusion
Overall, this study shows that with the increasing number of distillation columns, the purity of methanol produced also increases. This shows that a more complex distillation process can produce better quality products. The application of the right analysis method is also very important to ensure the accuracy of measurement and analysis of the purity of raw materials. These results can be a reference for the chemical industry, especially in methanol production, to improve product efficiency and quality.
