Abstract
A process for component separation in a polymer production system, comprising: separating a polymerization product stream into a gas stream and a polymer stream; contacting the polymer stream with a purge gas to yield a purged polymer stream and a spent purge gas stream; introducing the spent purge gas stream to a compressor to produce a compressed gas stream; introducing the compressed gas stream to a first separation unit to produce a first hydrocarbon stream and a membrane unit feed stream; introducing the membrane unit feed stream to a membrane unit to produce a first recovered purge gas stream and a retentate stream; introducing the retentate stream to a second separation unit to produce a second hydrocarbon stream and a PSA unit feed stream; and introducing the PSA unit feed stream to a PSA unit to produce a second recovered purge gas stream and a tail gas stream.
