FIELD: technological processes.
SUBSTANCE: invention relates to the polymerization unit, to the polymerization process, and downstream technological processes. Ethylene polymerization plant has a recirculation connection scheme with two or more parallel cooling channels. Plant contains the reactor, which c comprises the inlet side and the outlet side, as well as the recirculation connection circuit, which is located between the outlet side of the reactor and the inlet side of the reactor, and provides for a fluid communication between them.
EFFECT: increased energy efficiency, increase polymer yield and reduced plant downtime.
