Abstract
Proceso de recuperacion de un catalizador metálico de una corriente de purga oxidante producida en la síntesis de ácido carboxílico, típicamente ácido tereftálico. El proceso involucra el agregado de una solucion de lavado a una dispersion fusionada a alta temperatura para recuperar el catalizador metálico y después someter una mezcla acuosa o mezcla acuosa purificada así formada a una extraccion de una unica etapa para remover impurezas orgánicas a fin de producir una corriente de extracto y una corriente de rafinato que comprende el catalizador metálico.
