Abstract

Reivindicación 1: Un proceso para recuperar un catalizador de metal de una solución madre, dicho proceso comprende los siguientes pasos: a) evaporar dicha solución madre que comprende un ácido carboxílico, dicho catalizador de metal, impurezas, agua y un disolvente en una primera zona de evaporación para producir una corriente de vapor y una corriente de solución madre concentrada; b) evaporar dicha corriente de solución madre concentrada en una segunda zona de evaporación para formar una corriente rica en disolvente y una corriente de solución madre superconcentrada; c) separar impurezas orgánicas con una solución de agua-disolvente de dicha corriente de solución madre superconcentrada en una zona de separación de sólido-líquido para formar una corriente acuosa y una segunda corriente acuosa; d) mezclar en una zona de mezclado agua y opcionalmente un disolvente de extracción con dicha corriente acuosa y dicha segunda corriente acuosa para formar una mezcla acuosa; e) agregar un disolvente de extracción a dicha mezcla acuosa en una zona de extracción para formar una corriente de extracto y una corriente de refinado; y f) opcionalmente separar dicha corriente de extracto en una zona de separación para formar una corriente de impurezas orgánicas de alto punto de ebullición y una corriente de disolvente de extracción recuperado.
