A method of treating a polymerization reactor effluent stream comprising recovering the reactor effluent stream from the polymerization reactor, flashing the reactor effluent stream to form a flash gas stream, separating the flash gas stream into a first top stream, a first bottom stream, and a side stream, wherein the side stream substantially comprises hexane, separating the first top stream into a second top stream and a second bottom stream, wherein the second bottom stream substantially comprises isobutane, and separating the second top stream into a third top stream and a third bottom stream; wherein the third top stream substantially comprises ethylene, and wherein the third bottom stream is substantially free of olefins.
