Abstract

A plant for producing an ethylene polymer, the plant comprising a secondary compressor with an outlet; a temperature adjusting system with an inlet and an outlet, the temperature adjusting system being in fluid communication with the secondary compressor outlet; a reaction system with an inlet in fluid communication with the outlet of the temperature adjusting system, the reaction system comprising a tubular reactor, wherein the tubular reactor has two or more reaction zones, wherein each reaction zone comprises i) a reaction section having an inside diameter and ii) a super cooler downstream and in direct fluid communication with the reaction section; and a controller configured to allow that a fluid has a residence time in the reaction section of no more than 60 seconds; wherein the super cooler comprises two or more parallel flow tubes having an inside diameter smaller than the inside diameter of the reaction section. And a process for producing an ethylene (co)polymer by polymerizing ethylene or, alternatively, ethylene and a comonomer, in a plant as defined above.
