Abstract

In a method of recovering energy in the manufacture of high-pressure polyethylene from ethylene gas, the ethylene gas is compressed and partially converted into polyethylene in a reactor by polymerization. For the purpose of energy recovery, the polymer-gas mixture being discharged from the reactor is accelerated and decompressed in a nozzle system of an energy exchange unit, mixed and compressed with an almost polymer-free working stream. The polymer-free gas is then separated in a separation. The working stream flows through a decompression turbine, and is subsequently conveyed together with the polymer-gas mixture from the reactor into the nozzle system of the energy exchange unit and is continuously re-compressed in the energy exchange unit by the gas stream from the decompression turbine.
