Abstract
SE TRABAJA EN UNA UNIDAD DE OXIDACION (2A) QUE COMPRENDE, EN SERIE, TRES ETAPAS CATALITICAS (3A, 4A, 5A), DONDE CADA UNA CONTIENEN UN CATALIZADOR PROMOTOR DE LA OXIDACION SELECTIVA DE H2 S EN AZUFRE HASTA UNA TEMPERATURA S INFERIOR O IGUAL A 150º C. SE HACE PASAR EL GAS A TRATAR (16) SUCESIVAMENTE POR CADA UNA DE DICHAS ETAPAS Y SE INYECTA AIRE (50, 53A, 55A) EN CADA ETAPA. SE OXIDA A AZUFRE, DE MANERA ADIABATICA, UNA FRACCION DE H2 S DE DICHO GAS EN CADA UNA DE LAS DOS PRIMERAS ETAPAS (3A, 4A) CON UNA CANTIDAD DE AIRE QUE GARANTIZA QUE EN LA SALIDA DE ESTAS ETAPAS LA TEMPERATURA ES COMO MAXIMO S. SE OXIDA LA TOTALIDAD DEL H2 S DEL GAS QUE PASA EN LA ETAPA FINAL (5A) EN EXCESO CONTROLADO DE AIRE Y A UNA TEMPERATURA MAXIMA DE S. ESTE PROCEDIMIENTO ES DE APLICACION EN EL TRATAMIENTO DE GASES QUE CONTIENEN H2 S OBTENIDOS POR HIDROGENACION/HIDROLISIS DE GASES RESIDUALES EN FABRICAS DE AZUFRE.
