Abstract

METODO PARA ELIMINAR Y RECUPERAR AZUFRE EN FORMA ELEMENTAL DE GASES QUE CONTENGAN ANHIDRIDO SULFUROSO O ANHIDRIDO SULFUROSO Y ACIDO SULFHIDRICO. COMPRENDE: A) ABSORBER EN UNA SOLUCION DE DEPURACION AL ANHIDRIDO SULFUROSO O ANHIDRIDO SULFUROSO Y ACIDO SULFHIDRICO CONTENIDO EN LOS GASES, PARA QUE EL PH DE LA SOLUCION DEPURADORA PERMANEZCA ENTRE 2,5 Y 5 Y EL POTENCIAL DE OXIDACION-REDUCCION PERMANEZCA ENTRE C70 A C260 MV CON RESPECTO A UN ELECTRODO DE CALOMEL Y B) CONDUCIR LA SOLUCION DEPURADORA RESULTANTE A UN AUTOCLAVE, PARA QUE LOS COMPUESTOS REACCIONEN A UNA TEMPERATURA ENTRE 150 Y 300JC Y OBTENER AZUFRE ELEMENTAL FUNDIDO Y UNA SOLUCION DE SULFATO QUE ES REGENERADO EN SULFURO DE UNA MANERA CONDUCIDO Y CONDUCIDO A LA FASE DE ABSORCION. EL SULFURO EMPLEADO ES SULFURO SODICO O POTASICO, O SULFURO DE MANGANESO.
