Abstract
The present invention relates to an olefinic monomer recovery device capable of suppressing fouling and pressure drop in the recovery device in a process of separating and recovering unreacted monomers after production of a polyolefin resin. The olefinic monomer recovery device is used for separating and recovering unreacted olefinic monomers after production of a polyolefin resin, the apparatus comprising a vertical-type heat exchange unit, and a knock-out drum unit.
