Abstract

Patente de Invenção: "PROCESSO PARA SEPARAçãO DEOLEFINAS DE INSTALAçõES DE POLIOLEFINAS". A presenteinvenção refere-se a um processo para separação de olefinas deuma mistura de gás, que contém uma ou mais olefinas, gás inerte eveneno de catalisador, sendo que a mistura de gás é alimentada auma unidade de separação (18) e separada em olefina e gásinerte. O processo de acordo com a invenção tem a particularidadede que um aparelho (17) está ligado previamente oucomplementarmente à unidade de separação (18) e que i) no casode aparelho (17) ligado previamente, o veneno de catalisador éremovido, pelo menos parcialmente, da mistura de gás e ii) no casode aparelho (17) ligado complementarmente, o veneno decatalisador é removido, pelo menos parcialmente, da olefinaseparada. Nesse caso, as olefinas são preferivelmente separadasde uma mistura de gás, que na polimerização de fase gasosacatalítica para produção de poliolefinas se apresenta como gás deescapamento. A recuperação das olefinas do gás de escapamentoé de importância do ponto de vista económico.
