Abstract

"SISTEMA DE RECUPERAçãO DE ETILENO". Etileno é um produto químico usado como um reagente na produção de acetato de vinila. Etileno é relativamente caro, o que encoraja a sua recuperação e reutilização no processo. A presente invenção provê um processo para recuperação de etileno, da corrente de purga de gás inerte do circuito completo do reator, em um processo de fase vapor para fabricação de acetato de vinila. O processo da presente invenção inclui as etapas de contato da corrente de purga de gás contendo etileno com ácido acético em um recipiente de absorção; descarga de uma corrente contendo ácido acético e etileno de um aspecto do recipiente de absorção; separação do etileno de ácido acético na corrente por contato da corrente com gás etileno em uma coluna de purificação; e recuperação do etileno da porção superior da coluna de purificação. O processo pode também incluir a etapa de reciclo do etileno recuperado para o circuito completo do reator para uso posterior.
