Abstract

EL PROCESO CONSISTE EN INTRODUCIR LA SUSPENSION EN ACIDO CARBOXILICO ALIFATICO DEL ACIDO TEREFTALICO EN LA PARTE SUPERIOR DE UNA COLUMNA MULTIETAPAS E INTRODUCIR AGUA EN SU PARTE INFERIOR PARA FORMAR UNA CORRIENTE ASCENDENTE DE AGUA EN LA COLUMNA DE ETAPAS MULTIPLES, MIENTRAS SE PRODUCE LA SEDIMENTACION DE PARTICULAS DE ACIDO TEREFTALICO DENTRO DE LA COLUMNA Y EXTRAYENDO UNA DISOLUCION ACUOSA DE ACIDO CARBOXILICO ALIFATICO DESDE LA PARTE SUPERIOR Y UNA SUSPENSION ACUOSA DE ACIDO TEREFTALICO POR LA PARTE INFERIOR DE LA COLUMNA DE ETAPAS MULTIPLES.
