| titleOfInvention | Control of a continuous ethylene polymerization process in a high pressure reactor. |
| abstract | In a high pressure polymerization process for producing polyethylene and ethylene copolymers using oxygen or organic free radical formers as initiators, a method is provided for ensuring safe operation and high conversion and reducing production costs. The invention relates to a tube reactor having at least one reaction zone (1, 2, 3, 4) at a pressure above 1000 bar and a temperature range of 100 to 400 ° C., in the presence or absence of a comonomer. A method for controlling a continuous free radical polymerization process of ethylene under the conditions described above, wherein a mixture of at least two polymerization initiators having different reaction characteristics and supply costs, in particular a purchase price, is added to the reaction zone (1, 2, 3, 4) Continuously metering into the tube reactor at the beginning of; at least one physical parameter affecting the polymerization initiator mixture used is determined in each of the reaction zones (1, 2, 3, 4) Measured at intervals; under the prevailing conditions of the measured physical parameter or parameters, a mixture of polymerization initiators produces a predetermined amount of polymer product with a predetermined product property. And the reactor reactor (1, 2, 3, 4) reliably predicts safe operation of the tube reactor; and finally, the expected amount and composition of the polymerization initiator. Further providing said method for use as a reference for a metered addition. |
