Abstract:
1. An ethylene polymerization system comprising: a first compressor that provides a monomer under relatively low pressure; a second compressor located downstream of and in fluid communication with the first compressor, wherein the second compressor pressurizes the monomer to a relatively high pressure; a reactor located downstream of and in fluid communication with the second compressor, wherein the reactor polymerizes the monomer under relatively high pressure to produce a product mixture; a separation system downstream of and in fluid communication with the reactor; and a quench system that cools the product mixture entering the separation system, the quench system including a pump located downstream of and in fluid communication with the reactor, the pump having a suction inlet that receives at least a portion of the monomer under relatively low pressure from the first compressor such that the pressure of the monomer under relatively low pressure from the first compressor is less than a suction pressure of the second compressor.
