摘要：
A method of recovering and recycling monomers from a gas phase olefins polymerization reactor through the use of the monomer feed stream. A high pressure monomer source is reduced in pressure so as to reduce the temperature of the monomer source. The monomer source is then used to cool and condense monomers contained in various vent gas streams. The condensed monomers are then separated from the gas stream and recycled back to the reactor.
