Abstract: Method of improving the efficiency of polyolefin production comprising: performing a reaction to yield (1) a product stream comprising a polyolefin, and (2) a purge stream, wherein the purge stream comprises unreacted monomers, inert impurities and saturated co-monomers; compressing the purge stream in a first stage compressor to create a first compressed stream; cooling the stream first compressed stream in a cooler to create a cooled stream; directing the cooled stream to a first drum, to create a waste liquid stream and a first drum stream; removing the waste liquid stream from the first drum; compressing the first drum stream in a second stage compressor to create a second compressed stream; condensing the second compressed stream to produce a condensed stream; processing the condensed stream in a second drum to produce a second drum gas stream and a second drum liquid stream; and, sending at least a portion of the second drum liquid stream to a polyolefin reactor.
