Abstract

processo para a purificação do solvente derivado da produção de uma mistura elastomérica compreendendo as seguintes etapas: (a) opcionalmente, submeter o dito solvente a uma pré-lavagem (2) na presença de pelo menos uma solução aquosa ácida ou básica; (b) abastecer o dito solvente a uma coluna de separação líquido-líquido(7); (c) abastecer a corrente que sai da cabeça da dita coluna de separação líquido-líquido(21) a uma coluna de destilação azeotrópica; (d) abastecer a corrente retirada lateralmente (retirada lateral) da dita coluna de destilação azeotrópica(21) para uma seção de adsorção (34a/b); em que na etapa, o dito processo permite obter um solvente de grau polimérico tendo uma qualidade adequada para ser usado indiferente e contemporaneamente em vários tipos de usinas de produção de (co)polímeros elastoméricos, isto é, em usinas onde uma (co)polimerização aniônica é realizada, e também em usinas onde uma (co)polimerização ziegler-natta é realizada.
