Abstract

Una corriente de purgado de una columna de destilación azeotrópica y conteniendo un agente separador, un hidrocarburo, y un ácido alifático (porejemplo acetato de n-propilo, un xileno y ácido acético respectivamente) es procesada usandoun a columna rectificadora para efectuar la separación delagente separador y el hidrocarburo a fin de que dicho agente separador pueda ser reciclado hasta la columna de destilación azeotrópica.
