Chromatographic determination of the amount of fixed ammonium salts in tar
Thread Content
The corrosion damage caused by fixed ammonium salts in coal tar to equipment such as distillation columns is extremely severe. My organization incurs substantial costs each year on replacing the corroded distillation trays. Moreover, the amount of sodium carbonate added is not consistent; it’s only approximate, with no precise value. If it were possible to determine the amount of fixed ammonium salts in the tar using chromatography in real time, then the amount of sodium carbonate added could also be adjusted accordingly. If that expert has the relevant skills, we can consider matters such as technology transfer.
Actually, this problem isn’t that difficult; it involves some trial and error. After extracting coal tar, one can use ion chromatography for measurement. The key is to select the appropriate guard column and analysis column based on the characteristics of your own tar. Of course, it’s best to use a high-quality chromatography system, such as those made by Dionex in the United States.
One can go to another coking plant to learn*, and it works quite well there
I think online measurement is almost impossible
