ETHYLENE RECOVERY BY ABSORPTION

摘要

A process for recovery of ethylene from a polymerization product stream of a polyethylene production system comprising separating a light gas stream from the polymerization product stream wherein the light gas stream comprises ethane and unreacted ethylene contacting the light gas stream with an absorption solvent system wherein the contacting the light gas stream with the absorption solvent system occurs at a temperature in a range of from about 40° F to about 110° F wherein at least a portion of the unreacted ethylene from the light gas stream is absorbed by the absorption solvent system and recovering unreacted ethylene from the absorption solvent system to yield recovered ethylene.
