Abstract

separação de etileno aprimorada. a presente invenção refere-se a um processo de produção de polietileno, compreendendo entrar em contato com etileno e um catalisador de polimerização sob condições de reação adequadas para produzir um fluxo de produto de polimerização, separando um fluxo de gás leve do fluxo de produto de polimerização, onde o fluxo de gás leve compreende etano e etileno não reagido, entrar em contato com o fluxo de gás leve com um sistema de solvente de absorção, em que pelo menos uma porção de etileno do fluxo de gás leve é absorvida pelo sistema de solvente de absorção, removendo gases não absorvidos do fluxo de gás leve do contato com o sistema de solvente de absorção para formar um fluxo de gás residual e recuperar o etileno do sistema de solvente de absorção.
