Abstract
Un método para recuperar y regenerar un disolvente selectivo para hidrocarburos polares sustancialmente exento de hidrocarburos a partir de una de sus mezclas con hidrocarburos polares e hidrocarburos no polares, comprendiendo dicho método las etapas de : (a) introducir dicha mezcla en una primera columna de fraccionamiento, separar una corriente rica en hidrocarburos no polares de una parte superior de dicha primera columna y separar una primera corriente que contiene hidrocarburos polares rica en disolventes desde una parte inferior de dicha primera columna;
