Title:
OLEFINIC MONOMER RECOVERY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/093052
Kind Code:
A3
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 comprises a vertical-type heat exchange unit, and a knock out drum unit and is used for separating and recovering unreacted olefinic monomers after production of a polyolefin resin, the vertical-type heat exchange unit including: a heat exchange unit body in which a cooling medium for heat exchange is accommodated; and a plurality of heat transfer tubes which extend in a vertical direction and are installed in the heat exchange unit body so as to be submerged in the cooling medium and through which a gas containing an olefinic monomer and a polyolefin wax passes, and the knock out drum unit including: a gas injection port directly connected to the heat transfer tubes of the vertical-type heat exchange unit; a knock out separating means for separating an olefinic monomer-containing gas and a polyolefin wax-containing liquid from the gas; a first discharge tube, installed at an upper portion of the knock out drum unit, for discharging the olefinic monomer-containing gas; and a second discharge tube, installed at a lower portion of the knock out drum unit, for discharging the polyolefin wax-containing liquid.
