Abstract

EN UN PROCESO DE DESULFURIZACION DE UN GAS COMBUSTIBLE SEGUN EL CUAL, CUANDO EL GAS DE ESCAPE QUE CONTIENE OXIDO DE AZUFRE SE TRATA CON UNA SOLUCION DE ABSORCION QUE CONTIENE UN COMPUESTO DE CALCIO, SE HACE PASAR A UN GAS QUE CONTENGA OXIGENO A TRAVES DE LA SOLUCION DE ABSORCION Y SE CONTROLA LA VELOCIDAD DE FLUJO DEL GAS QUE CONTIENE OXIGENO DETECTANDO DE FORMA CONTINUA EL POTENCIAL DE OXIDACION-REDUCCION DE LA SOLUCION DE ABSORCION Y SE LLEVA A CABO UN METODO DE CONTROL DE LA OXIDACION QUE CONSISTE EN DETECTAR UNA PRIMERA SEÑAL DE DESVIACION ENTRE EL POTENCIAL DE OXIDACION-REDUCCION DE LA SOLUCION DE ABSORCION Y EL POTENCIAL DE OXIDACION-REDUCCION DE LA SOLUCION DE ABSORCION EN UN ESTADO TOTALMENTE OXIDADO Y CONTROLAR LA VELOCIDAD DE FLUJO DEL GAS QUE CONTIENE OXIGENO EN RESPUESTA A UNA SEGUNDA SEÑAL DE DESVIACION ENTRE LA PRIMERA SEÑAL DE DESVIACION Y UN VALOR DE DESVIACION DEL POTENCIAL DE OXIDACION-REDUCCION PREESTABLECIDO.
