Abstract

LA PRESENTE INVENCION SE REFIERE A UN METODO PARA CONTROLAR LA OXIDACION DE SULFITOS, PARA UTILIZACION EN UN PROCESO DE DESAZUFRAMIENTO DE GAS DE COMBUSTION, BASADO EN EL METODO DE LA CAL HUMEDA-YESO. DICHO PROCEDIMIENTO COMPRENDE LAS SIGUIENTES FASES: DETECTAR UNA PRIMERA SEÑAL DE DESVIACION (47) ENTRE EL POTENCIAL DE OXIDACION-REDUCCION (ORP) DE UN FLUIDO ABSORBENTE (3) Y EL ORP DEL FLUIDO ABSORBENTE EN UN ESTADO COMPLETAMENTE OXIDADO, MEDIANTE UN DETECTOR DE ORP EQUIPADO CON UN TANQUE DE FLUIDO DE MUESTRA (31) PARA DETECTAR EL ORP DEL FLUIDO ABSORBENTE Y UN TANQUE DE FLUIDO DE REFERENCIA (32) PARA OXIDAR EL FLUIDO ABSORBENTE MEDIANTE EL PASO DE AIRE A TRAVES DEL MISMO Y DETECTAR EL ORP DEL FLUIDO ABSORBENTE EN UN ESTADO COMPLETAMENTE OXIDADO; CONTROLAR LA VELOCIDAD DE FLUJO DE UN GAS QUE CONTENGA OXIGENO CONDUCIDO A TRAVES DEL FLUIDO ABSORBENTE, EN RESPUESTA A UNA SEGUNDA SEÑAL DE DESVIACION ENTRE LA PRIMERA SEÑAL DE DESVIACION (47) Y UN VALOR DE DESVIACION DE ORP PREFIJADO. DICHO METODOSE CARACTERIZA PORQUE EL POTENCIAL DE OXIDACION-REDUCCION TOTAL SE MIDE MEDIANTE LA DESCOMPOSICION DE LOS PEROXIDOS PRESENTES EN EL FLUIDO ABSORBENTE CON AYUDA DE UN AGENTE QUIMICO SUMINISTRADO MEDIANTE VALVULAS (36, 37, 38) Y TEMPORIZADORES (39, 40, 41) Y HACIENDO PASAR AIRE A CONTINUACION, A TRAVES DEL FLUIDO ABSORBENTE. POR TANTO, EL POTENCIAL DE OXIDACION-REDUCCION TOTAL SE MIDE CORRECTAMENTE EN UN PROCEDIMIENTO DE DESAZUFRAMIENTO DE GAS DE ESCAPE, EN DONDE LA OXIDACION DEL SULFITO DE CALCIO EN EL FLUIDO ABSORBENTE SE PUEDE CONSEGUIR EFICIENTEMENTE.
