Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA REGENERACION DE ACIDO SULFURICO IMPURIFICADO MEDIANTE CALENTAMIENTO INDIRECTO. CONSISTE EN INTRODUCIR EN UNA UNIDAD DE PURIFICACION EL ACIDO SULFURICO IMPURIFICADO CON UNA CONCENTRACION DEL 90 AL 98,3 POR 100 EN PESO DE H2SO4 Y SOMETERLO EN LA ZONA DE CALENTAMIENTO (A) A UNA TEMPERATURA COMPRENDIDA ENTRE 140 Y 330 GRADOS, DESPUES SE LE PASA A LA ZONA DE REACCION (C), DONDE SE LE SOMETE A UNA PRESION COMPRENDIDA ENTRE 100 TORR Y LA ATMOSFERA, Y, POR ULTIMO, SE LE PASA A LA ZONA DE REACCION ULTERIOR, DONDE SE LA MANTIENE A UNA TEMPERATURA DE 330 GRADOS Y A UNA PRESION NORMAL O INFERIOR, CONSIGUIENDOSE LA PURIFICACION DEL ACIDO, CUYA CONCENTRACION EN LA ZONA DE SALIDA DEL REFRIGERADOR MEZCLADO (D) ES, COMO MINIMO, DEL 96 POR 100 EN PESO DE H2SO4. EL DISPOSITIVO CONSTA EN ESENCIA DE UNA UNIDAD DE PURIFICACION FORMADA POR UN TUBO DE CRISTAL DE CUARZO CALENTADO POR RADIACION, ESTANDO DICHO TUBO RODEADO POR UNA ENVOLTURA CONCENTRICA Y ESTA A SU VEZ POR UNA RESISTENCIA DE CALEFACCION ELECTRICA. EL SISTEMA OFRECE VARIANTES. A
