Abstract

PROCEDIMIENTO PARA LA PURIFICACION TOTAL DE GASES CALIENTES DE TOSTACION O COMBUSTION QUE CONTIENEN SO2.COMPRENDE TRES ETAPAS; EN UNA PRIMERA ETAPA EL GAS BRUTO CALIENTE SE ENFRIA EN UNA PRIMERA TORRE DE LAVADO (2) EN EQUICORRIENTE CON ACIDO SULFURICO DILUIDO Y CALIENTE, CON UNA CONCENTRACION DE 5 A 20 DE ACIDO SULFURICO, QUE ES CONDUCIDO EN CIRCUITO A TRAVES DEL RECIPIENTE (8) Y DE LA BOMBA (9). EL GAS QUE ABANDONA (2) ES ENFRIADO HASTA CASI EL PUNTO DE ROCIO A TRAVES DE LA CONDUCCION (3). ES UNA SEGUNDA ETAPA SE EFECTUAN DENTRO DE UNA SEGUNDATORRE DE LAVADO (4), LLENA CON CUERPOS DE RELLENO, EL LAVADO Y EL ENFRIAMIENTO ULTERIORES DEL GAS EN CONTRACORRIENTE. EN EL LAVADO DEL GAS, EL ACIDO, CALENTADO POR CONDENSACION CON AGUA, CIRCULA DESDE LA PARTE INFERIOR DE (4) AL RECIPIENTE (13), DESDE DONDE LA BOMBA (14) LO ENVIA A TRAVES DEL REFRIGERADOR (15) A LA PARTE SUPERIOR DE (4). EN UNA TERCERA ETAPA EL GAS ES SOMETIDO A UNA PURIFICACION EN UNOS FILTROS ELECTRICOS EN HUMEDO (6), PARA SU TRATAMIENTO ULTERIOR, CON EL FIN DE PREPARAR ACIDO SULFURICO O DIOXIDO DE AZUFRE PURO.
