Abstract
METODO PARA REGENERAR TERMICAMENTE UN GAS ACIDO AGOTADO PROVENIENTE DE LA DEPURACION DE LOS GASES DE ESCAPE, QUE CONTIENEN DIOXIDO DE AZUFRE, FORMADOS EN EL PROCESO PIROMETALURGICO DE METALES. ESTE METODO COMPRENDE: i) EL GAS ACIDO AGOTADO ES CONCENTRADO, PRIMERO POR EVAPORACION INDIRECTA AL VACIO Y LUEGO POR EVAPORACION DIRECTA POR INMERSION, Y SE ELIMINA LA MAYOR PARTE DE METALES PESADOS, HALOGENOS Y ARSENICO CONTENIDOS EN EL GAS ANTES DE REGENERARLO; ii) EL GAS ACIDO AGOTADO ES ALIMENTADO DENTRO DEL ESPACIO DEL GAS DE UN HORNO DE FUSION PRINCIPAL, SIENDO LA ENERGIA NECESARIA PARA LA REGENERACION TERMICA DEL GAS ACIDO AGOTADO APROVECHADA DEL CONTENIDO CALORIFICO DE LOS GASES CALIENTES FORMADOS EN EL PROCESO PIROMETALURGICO. ADEMAS LA TEMPERATURA EN EL HORNO DE FUSION PRINCIPAL SE ENCUENTRA ENTRE 1000°C Y 1600°C. EL DIOXIDO DE AZUFRE FORMADO EN LA REGENERACION DEL GAS ACIDO AGOTADO ES RECUPERADO, ADEMAS DEL RESTO DE DIOXIDO DE AZUFRE, CON EL FIN DE PRODUCIR ACIDO SULFURICO O AZUFRE ELEMENTAL
