Abstract

EN UN PROCEDIMIENTO PARA PRODUCCION DE UN ACIDO DICARBOXILICO AROMATICO COMO ACIDO TEREFTALICO MEDIANTE LA OXIDACION EN FASE LIQUIDA DE UN PRECURSOR (P. EJ., P-XILENO) DEL MISMO, UNA CORRIENTE SUPERIOR (10) QUE COMPRENDE UN ACIDO CARBOXILICO ALIFATICO ACUOSO ES SOMETIDA A DESTILACION ACEOTROPICA EN COLUMNA (12) PARA REDUCIR EL CONTENIDO DE AGUA. LA DESTILACION ACEOTROPICA PUEDE LLEVARSE A CABO UTILIZANDO REFLUJO DEL PRODUCTO TRANSPORTADO SOLO (22) CON CONTROL DE PENETRACION DEL PRODUCTO TRANSPORTADO PARA OBTENER UN PRODUCTO FINAL (34) QUE ESTA SUSTANCIALMENTE LIBRE DE PRODUCTO TRANSPORTADO Y CONTIENE UNA CANTIDAD PREDETERMINADA DE AGUA RESIDUAL. CUALQUIER PRECURSOR DE ACIDO DICARBOXILICO AROMATICO PRESENTE EN LA CORRIENTE SUPERIOR ES SEPARADO DEL ACIDO CARBOXILICO ALIFATICO MEDIANTE SEPARACION EN UNA LOCALIZACION (24) EN LA VECINDAD DEL PUNTO DE INTRODUCCION DEL PRODUCTO DE PARTIDA (10) EN LA COLUMNA. LA CANTIDAD DE AGUA EN EL PRODUCTO FINAL (34) PUEDE SER CONTROLADA MEDIANTE REGULACION DEUN PRODUCTO DE PARTIDA DE AGUA SEPARADA (76) EN LA SECCION INFERIOR DE LA COLUMNA DE DESTILADO ACEOTROPICO. ADEMAS, LA REGULACION DE LA VELOCIDAD DE REFLUJO (VIA LINEA 22) PUEDE SER EMPLEADA PARA CONTROLAR EL CONTENIDO DE AGUA DEL PRODUCTO FINAL Y MANTENER EL FUNCIONAMIENTO DE LA COLUMNA EN CASO DE PERDIDA DE PRODUCTO DE PARTIDA EN LA COLUMNA.
