Abstract

Un método de control de la introducción de un agente reductor, como por ejemplo urea o amoníaco, a un reactor de reducción catalítica selectiva (12), que opera removiendo NOx de un gas de proceso de una planta de proceso (1), que comprende los pasos de estimar el valor presente de al menos un parámetro predeterminado que es indicativo de la cantidad de NOx que es necesario remover de dicho gas de proceso en el reactor de reducción catalítica selectiva. Luego se estima la tasa de aumento de dicho - al menos uno - parámetro selectivo. Cuando dicha tasa estimada de aumento de dicho parámetro - al menos uno - predeterminado resulta ser positiva, la cantidad de dicho agente reductor suministrado, se incrementa hasta un valor superior que el que habría sido si el parámetro predeterminado se hubiera mantenido constante al valor estimado presente.
