Abstract

PROCESSO PARA A PRODUçãO DE UM PRODUTO E DE UMA CORRENTE RICOS EM PARA-XILENO. A presente invenção refere-se a um processo para a produção de um produto rico em PX que compreende: (a) a separação de uma matéria-prima contendo hidrocarbonetos C~8~ para produzir uma corrente rica em hidrocarbonetos C~8~; (b) a separação de pelo menos uma primeira parte da corrente rica em hidrocarbonetos C8 para produzir uma primeira corrente rica em PX e uma primeira corrente depletada de PX; (c) a isomerização de pelo menos uma parte da primeira corrente depletada de PX para produzir uma primeira corrente isomerizada com uma concentração de PX maior que a da primeira corrente depletada de PX; (d) a separação de uma segunda parte da corrente rica em hidrocarbonetos C~8~ e/ou pelo menos uma parte da primeira corrente isomerizada para produzir uma segunda corrente rica em PX e uma segunda corrente depletada de PX; (e) a isomerização de pelo menos uma parte da segunda corrente depletada de PX para produzir uma segunda corrente isomerizada com uma concentração de PX maior que a da segunda corrente depletada de PX; (f) a recuperação de pelo menos uma parte de pelo menos uma das primeira e segunda correntes ricas em PX como produto rico em PX; e (g) o suprimento de pelo menos uma parte de pelo menos uma das primeira corrente isomerizada, segunda corrente isomerizada, primeira corrente rica em PX e segunda corrente rica em PX para a separação (a).
