Abstract
El proceso se refiere al mejoramiento de la velocidad de filtración de la purga del ácido tereftálico mediante el control del porcentaje de agua en la lechada de la alimentación al filtro así como a la recuperación de un catalizador de metal a partir de una corriente de purga de oxidante que se produjo en la síntesis de ácido carboxílico, típicamente ácido tereftálico, mientras se utiliza filtración a presión.
