ABSTRACT:
The present invention provides a method of separating unreacted monomer from a polymerization process effluent stream. The polymerization process effluent stream has at least the following components: unreacted monomer, polymer, and solid fines. The method comprises passing the effluent stream through one or more filters disposed within a vessel at a pressure of from about 150 psig to about 400 psig and thereby obtaining a stream of vapor containing less than about 0.5 weight percent solid fines.
