Industrial drying methods for the by-product chloromethane of glyphosate
Thread Content
As we all know, chloromethane, a by-product of glyphosate, needs to be dried in industrial production, and different manufacturers use various methods for this purpose. Common methods include drying with sulfuric acid, subcooled drying, and pressure absorption drying. We hope that those with experience in this area can join the discussion to explore the advantages and disadvantages of each drying method.
The main technology for sulfuric acid drying originates from the purification system for synthetic chloromethane. Drying with sulfuric acid can keep the water content in the finished product between 75 and 100 ppm. It can reach top-quality standards. This method primarily uses three sulfuric acid towers for absorption, and the type of tower is a packed tower.
