Abstract

Un procedimiento para recuperar glicoles producidos durante la circulacion del poliéster que consta del paso de extraer los contaminantes aromáticos de los glicoles. Se efectua la extraccion de los contaminantes aromáticos por medio de: proveer una corriente rica en glicoles a partir de un procedimiento para recircular poliéster. La corriente rica en glicoles consta de glicoles, agua y contaminantes aromáticos. Se agrega un solvente a la corriente rica en glicoles para formar una mezcla. Se descompone la mezcla para formar un componente rico en glicoles y un componente rico en contaminantes aromáticos. Se recupera los glicoles del componente rico en glicoles.
