Ethylene and alpha-olefin polymerization apparatus and preparation method |
| abstract |
An apparatus and method for economically copolymerizing ethylene and alpha-olefin by reusing reacting raw materials and solvents, comprising: a polymerization reactor where ethylene and alpha-olefin are supplied as reaction raw materials with a solvent, and the reaction raw materials are copolymerized in a solution state to produce a polymerization product comprising a dissolved ethylene and alpha-olefin copolymer; a unit for separating unreacted ethylene, alpha-olefin, low molecular weight oligomer and a polymer, including a flash tower for distilling and separating the unreacted ethylene and alpha-olefin from the polymerization product, and a stripper unit for distilling and separating the solvent and the low molecular weight oligomer having a molecular weight lower than the molecular weight of the ethylene and alpha-olefin copolymer 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 to recover the solvent. |
