SEPARATING SYSTEM TO REDUCE THE EMISSION OF SOLIDS DURING RELAXATION PROCESSES IN HIGH PRESSURE POLYMERIZATION REACTORS

SEPARATING SYSTEM TO REDUCE THE EMISSION OF SOLIDS DURING RELAXATION PROCESSES IN HIGH PRESSURE POLYMERIZATION REACTORS

Separating system (1 to 11) for tubular reactors or autoclaves used for the polymerisation of ethylene or copolymerisation of ethylene with ethylenically unsaturated comonomers in the presence of initiators at pressures of from 500 to 4000 bar and temperatures of from 150 to 350 DEG C, for reducing...

Zusammenfassung:Separating system (1 to 11) for tubular reactors or autoclaves used for the polymerisation of ethylene or copolymerisation of ethylene with ethylenically unsaturated comonomers in the presence of initiators at pressures of from 500 to 4000 bar and temperatures of from 150 to 350 DEG C, for reducing the emission of solids during relaxation processes of the reaction mixture present in the reactor or autoclave, characterised in that the relaxed reaction mixture is passed through at least two separating tanks (1, 1a) installed in series, before reaching the atmosphere.
