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 wherein the gas stream comprises ethane and unreacted ethylene distilling the gas stream into a light hydrocarbon stream wherein the light hydrocarbon stream comprises ethane and unreacted ethylene contacting the light hydrocarbon stream with an absorption solvent system wherein at least a portion of the unreacted ethylene from the light hydrocarbon stream is absorbed by the absorption solvent system and recovering a waste gas stream from the absorption solvent system wherein the waste gas stream comprises ethane hydrogen or combinations thereof.
