Abstract: 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.

Abstract: Screw extruder for removing gaseous constituents from plastic materials, comprising a screw surrounded by a barrel with a feed opening for the materials to be treated, a drive unit and a degassing device arranged between the feed opening and the drive unit. The degassing device is formed by a stuffing box housing (4), which covers over and seals off the screw (2), is connected positively and non-positively to the barrel (1) and has on its inner wall (6), on the side facing the barrel, a spiral groove (7) running counter to the cut of the screw, and adjoining the said spiral groove an eccentric annular chamber which has one or more openings. The said screw extruder is characterised in that a defined amount of paraffin oil is pumped into the spiral groove of the degassing ring.
