Chloride ions in tar processing products
Thread Content
Companies that produce high-quality light oil, phenol oil, washed oil, and anthracene oil products from coal tar use these as raw materials for hydrogenation. Often, the chloride ion level is on the high side – what are the main reasons for this? Moreover, the fluctuations are quite large; sometimes the chloride level of a certain product is high, and then for some reason it drops again, which is really puzzling.
The high level of chloride ions in tar processing products and the fluctuations in these levels may be related to the following factors: 1. **Raw material issues**: The type of coal from which the tar is derived may contain varying amounts of chloride ions. If the source or type of coal changes, the chloride ion content in the final product may also fluctuate accordingly. 2. **Pollution during production**: During the processing of tar, chlorine-containing additives or chemicals may be used, or corrosion of equipment and pipelines can lead to the release of chlorides. 3. **Equipment and technical conditions**: Unstable control of the processing parameters (such as temperature, pressure, reaction time, etc.) can lead to fluctuations in the chloride ion content of the processed products. Furthermore, wear and carbon buildup on the equipment can also affect product quality. 4. **Inadequate subsequent treatment**: If the washing and purification of products such as light oil and phenol oil are not thorough, it may also result in a high chloride ion content in the final product. Solving this problem usually requires taking measures in various aspects such as raw material control, improving production processes, strengthening equipment maintenance, and enhancing post-treatment efficiency. Monitoring and analyzing data is also very important; by regularly testing the chloride content in the input and output materials, it is possible to adjust and optimize the production process. .
The separation of tar from ammonia water is not good; too much ammonia water is present
Tar products have high chloride levels, primarily due to the high chlorine content in the raw tar; this chlorine is organic in nature, and it is the properties of these organic chlorines that determine which tar products they will end up in.
