Summary:Embodiments of a process and a plant for manufacturing polyethylene and ethylene based copolymers in which a) a compressor unit feed stream (10), comprising ethylene, is fed into a compressor unit (1) for increasing the pressure for a reactor (2) for radical polymerization of the ethylene, b) a compressor unit output stream (11) of more than 1 t/h is fed into the reactor (2), and c) wherein a gas purification unit (5) separates comonomers and / or chain transfer agents from a gaseous stream (15) downstream from the reactor (2).
