How to recycle PVC monomer produced by suspension method?
Thread Content
Please tell me how to recycle the monomer after the reaction of PVC produced by suspension method? Thank you!!! I didn’t understand it from the operating instructions.
Degassing, washing, compressor compression. I don’t know what LZ wants to say

Maybe the process is different. Mine is 'after being washed by the stripping tower, it enters the steam cabinet or pressure buffer tank and then enters the compressor. The compressor part has condensation before the machine and condensation after the machine. The condensate is vinyl chloride, and the non-condensable gas is vented.
Does the steam from the stripper enter the gas cabinet directly without condensation? How to remove the water vapor inside?
Haha, sorry. I forgot to say that. Mine is a polymerization of three monomers. Vinyl chloride is just one of them, and it has the lowest boiling point. The other two monomers have already passed through the condenser when recycling them. That is to say, most of what enters the buffer tank is vinyl chloride, and a small amount of water and other high-boiling point monomers are exhausted by the exhaust valve of the buffer tank.
