Beschreibung
Zusammenfassung:	A method of treating a polymerization reactor effluent stream comprising: recovering the effluent stream from the polymerization reactor, flashing the effluent stream to form a flash gas stream, feeding the flash gas stream into a first column, recovering a first overhead stream, a first bottom stream, and a side stream, from the first column, wherein the side stream substantially comprises hexane, feeding the first overhead stream into an accumulator vessel, recovering a second overhead stream and a second bottom stream from the accumulator vessel, wherein the second bottom stream substantially comprises isobutane, feeding the second overhead stream to a second column, and recovering a third overhead stream and a third bottom stream from the second column, wherein the third bottom stream is substantially olefin-free.
