ABSTRACT:
A high-pressure separator with improved efficiency is provided. The separator comprises a centrifugal separator located inside of a gravity separator. The centrifugal separator has an enclosed upper portion and desirably comprises a single cylinder. The high-pressure separator is particularly suitable for use in the production of low-density polyethylene under high pressure.
