Title:
ETHYLENE AND ALPHA-OLEFIN POLYMERIZATION APPARATUS AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/102423
Kind Code:
A1
Abstract:
Disclosed are an apparatus and a method for polymerization that can economically copolymerize ethylene and alpha-olefin by reusing reaction raw materials and solvents. The apparatus for polymerization of ethylene and alpha-olefin comprises: a polymerization reactor in which ethylene and alpha-olefin are supplied as reaction raw materials along with a solvent, and the reaction raw materials are copolymerized in a solution state, to thereby produce a polymerization product comprising an ethylene and alpha-olefin copolymer dissolved in the solvent; a unit for separating unreacted ethylene, the alpha-olefin, low molecular weight oligomer and a polymer, including a flash tower for distilling and separating the unreacted ethylene and alpha-olefin contained in the polymerization product, and a stripper unit for distilling and separating the solvent and the low molecular weight oligomer having a lower molecular weight than the molecular weight of the ethylene and alpha-olefin copolymer contained in the polymerization product; and a solvent recovery unit for separating the low molecular weight oligomer from the separated low molecular weight oligomer and solvent and recovering the solvent.
