What kind of protection is needed when the recovered monomer is fed directly into the condenser during discharge from the polymerization reactor?
Thread Content
As the title suggests, will directly recovering the monomer from the reactor cause foam to be carried away due to high flow rates, thereby blocking the pipelines or condenser?
The recovery speed can be appropriately controlled； The blockage of the condenser tubes is merely a matter of time; it is recommended to clean them regularly.
Are there any cyclone separators or filters available?
In our process, during material discharge and recovery, it first passes through a foam catcher, then a filter with a precision of 20um, and finally the compressor.

The EVC technology is employed; in the 105-tank system, the material is recovered by passing it through a discharge trough before being compressed and condensed for recovery. A washer is installed at the top of the discharge trough to prevent the slurry from being carried along, and there is no flash tank. The pipeline is flushed after the kettle is recovered.
I think it should be connected directly to the outlet of the compressor and the inlet of the condenser, so that condensation can take place directly under the pressure of the polymerization tank, which can help reduce energy consumption and the load on the compressor
When you say to go further into the compressor, do you mean the inlet or the outlet of the compressor?
The recovery pipeline coming out of the polymerization reactor passes through a foam trap and a recovery filter to prevent foam from being carried along. One pipeline leads directly to the condenser, while another pipeline goes through the compressor before reaching the condenser. You plan to carry out recovery using the pressure in the reactor, but what if the pressure in the reactor is too low toward the end of the material extraction process? Condensate recovery requires both cooling and pressure. Don’t forget to add a polymerization inhibitor to the pipeline.
