Abstract
"PROCESSO PARA ELABORAR UMA CORRENTE DE FUNDO, E, USO DO MESMO". A invenção está relacionada a método para reprocessar um fluxo de fundo que contém produtos com alto ponto de ebulição e um líquido iónico, produzidos de uma destilação extrativa, usando o líquido iónico como agente de arraste. O método da invenção é caracterizado por suprir o fluxo de fundo para um estágio de evaporação que é operado a uma pressão abaixo de 500 mbar ou por suprir o mesmo a um separador que é operado com um gás inerte ou com vapor, e por separar o produto com alto ponto de ebulição, obtido do líquido iónico, principalmente em uma forma de vapor.
