Regarding the issue of chloromethane drying
Thread Content
Currently, the drying of chloromethane is carried out using 98% sulfuric acid for three-stage drying. The waste sulfuric acid resulting from this process is difficult to handle due to its high content of impurities. Could molecular sieves be used for the drying of chloromethane? Or should both be used together to reduce the amount of sulfuric acid used? Has anyone tried this?
Molecular sieves can also be regenerated
Chloromethane can be dehydrated using activated alumina or molecular sieves; offline communication is available if needed
It’s capable of handling dozens of cubic meters, hundreds of cubic meters, or even thousands of cubic meters per minute

Large-scale dehydration and drying of chloromethane can no longer be carried out using concentrated sulfuric acid; it’s easy to introduce sulfuric acid into the process, but difficult to remove its impurities. Currently, horizontal spiral laser sieve filtration centrifuges are being widely adopted; after solid-liquid separation, dry chloromethane remains as dry chloromethane, and water remains as water. Molecular sieves cannot be used for large-scale processing, which affects production efficiency.
