METHOD AND APPARATUS FOR THE PREPARATION OF A POLYOLEFIN
The invention relates to a method (100) for producing a polyolefin from olefin monomers, wherein the olefin monomers are subjected to one or more polymerization steps (13), in which a portion of the olefine monomers is catalytically converted into the polyolefin, wherein the olefin monomers that are...

| description | The invention relates to a method (100) for producing a polyolefin from olefin monomers, wherein the olefin monomers are subjected to one or more polymerization steps (13), in which a portion of the olefine monomers is catalytically converted into the polyolefin, wherein the olefin monomers that are not converted in the one or more polymerization steps (13) are at least partially transferred into one or more gaseous, monomer-containing discharge flows (g, h), which additionally contain one or more aluminum organic compounds, said one or more aluminum organic compounds being one or more co-catalysts used in the one or more polymerization steps (13) and/or one or more compounds formed from the one or more co-catalysts. According to the invention, downstream of one or more olefin synthesis steps (21), the one or more gaseous, monomer-containing discharge flows (g, h) are brought into contact with a raw gas mixture (p, r), which is formed by using a product mixture of the one or more olefin synthesis steps (21), and are subjected to a caustic wash (26) together with the raw gas mixture (p, r). The invention further relates to a corresponding device. |
