Abstract

La invención se refiere a un método para la producción de urea y a una planta de producción de urea en donde se reduce la emisión de amoníaco en el paso final de formación de gránulos. En el método, la concentración de una solución de urea se lleva a cabo en al menos tres pasos de concentración consecutivos y se minimiza el tiempo de residencia de urea fundida que deja un último concentrador a la torre de granulación. Esto se puede lograr al colocar el último concentrador adyacente a la entrada de urea fundida de la torre de granulación, tal como por encima de la torre de granulación. De esta forma, se puede reducir la emisión de amoníaco en la torre de granulación en tanto como el 50% en comparación con las plantas de producción de urea convencionales. La invención además se refiere a un método para reducir la emisión de amoníaco en la torre de granulación de una plantaexistente para la producción de urea.
