Abstract

UN METODO PARA RECUPERAR ACIDOS CARBOXILICOS DE UNA SOLUCION ACUOSA DILUIDA QUE TIENE UNA CONCENTRACION POR DEBAJO DE ALREDEDOR DE DIEZ POR CIENTO (10%) DE PESO, QUE INCLUYE PASAR LA SOLUCION ACIDA DILUIDA A TRAVES DE UN SEPARADOR DE OSMOSIS INVERSA, POR LO QUE PRODUCE UN FILTRADO SUSTANCIALMENTE LIBRE DE ACIDO Y UN RETENIDO QUE TIENE UNA CONCENTRACION ACIDA SOBRE ALREDEDOR DE DIEZ POR CIENTO (10%) DE PESO. EL PRODUCTO RETENIDO ES PUESTO EN CONTACTO CON UN LIQUIDO EXTRACTOR DE ACIDO PARA PRODUCIR UN PRODUCTO EXTRAIDO RICO EN ACIDO Y UN REFINADO LIBRE DE ACIDO. EL ACIDO ES ENTONCES RECUPERADO DEL PRODUCTO EXTRAIDO RICO EN ACIDO.
