Abstract
El proceso se refiere a la forma de mejorar la velocidad de filtrado de purga de ácido tereftálico mediante el control del porcentaje de agua en la suspensión de alimentación del filtro y a la recuperación de un catalizador metálico de un flujo de purga oxidante que se produce en la síntesis de ácido carboxílico, típicamente ácido tereftálico, mientras se utiliza el filtrado a presión.Reivindicación 1: Un proceso de purga a base de ácido tereftálico que comprende: (a) someter un flujo de purga oxidante que se forma en un proceso a base de ácido tereftálico a la evaporación en una primera zona de evaporación para producir un primer flujo de vapor y un flujo de purga concentrado; donde dicho flujo de purga oxidante comprende un ácido carboxílico, un catalizador de metal, impurezas, agua y un solvente; donde dicho solvente comprende ácido acético; y (b) agregar agua a dicho flujo de purga concentrado en una primera zona de mezclado para producir un flujo de purga concentrado rico en agua; (c) someter dicho flujo de purga concentrado rico en agua a evaporación en una segunda zona de evaporación para producir un segundo flujo rico en vapor y un flujo de suspensión de purga concentrada; y (d) agregar agua a la suspensión de purga súper concentrada en una segunda zona de mezclado para producir una suspensión de purga súper concentrada rica en agua; (e) filtrar dicha suspensión de purga súper concentrada rica en agua en una zona de separación de sólidos y líquidos para formar una torta de filtro y el licor madre; (f) lavar dicha torta de filtro con un material de lavado en dicha zona de separación de sólidos y líquidos para formar una torta de filtro lavada, y el filtrado de lavado; (g) agregar agua a dicho licor madre en una tercera zona de mezclado para recuperar el catalizador de metal y, luego, someter una mezcla acuosa formada de esta manera a la extracción con un solvente de extracción para producir un flujo de extracción y un flujo refinado que comprende un catalizador de metal.
