PROCESS FOR THE PREPARATION OF ETHYLENE HOMOPOLYMERS OR COPOLYMERS IN A HIGH-PRESSURE REACTOR CONTROLLED BY A MODEL BASED PREDICTIVE CONTROLLER

PROCESS FOR THE PREPARATION OF ETHYLENE HOMOPOLYMERS OR COPOLYMERS IN A HIGH-PRESSURE REACTOR CONTROLLED BY A MODEL BASED PREDICTIVE CONTROLLER

Process for the preparation of ethylene homopolymers or copolymers in the presence of free-radical polymerization initiator at from 100° C. to 350° C. and pressures in the range of from 160 MPa to 350 MPa in a high-pressure polymerization unit comprising a high-pressure reactor with one or more reac...

Zusammenfassung:Process for the preparation of ethylene homopolymers or copolymers in the presence of free-radical polymerization initiator at from 100° C. to 350° C. and pressures in the range of from 160 MPa to 350 MPa in a high-pressure polymerization unit comprising a high-pressure reactor with one or more reaction zones, to each of which free-radical polymerization initiator is fed, which is controlled by a model based predictive controller carrying out the steps.
