Abstract

La presente invención se refiere a un método y a un dispositivo para oxidar una solución de absorción para la desulfuración de amoníaco en una columna de oxidación, donde la solución de absorción se envía a una columna de oxidación desde una columna de absorción para desulfuración de amoníaco y se envía una solución oxidada a la columna de absorción para la desulfuración de amoníaco desde la columna de oxidación, realizando de esta manera una circulación de múltiples etapas de la solución de absorción; y durante la oxidación en la columna de oxidación, se usa aire presurizado como aire de oxidación y se utiliza una distribución de aire de varias etapas para una oxidación obligatoria de la solución de absorción, para disminuir los costos de inversión y operación y controlar la producción de aerosol durante la desulfuración de amoníaco.
