Abstract

Aparatos y métodos para controlar el escape de amoníaco en un sistema de descarbonización a base de amoníaco, en donde el amoníaco puede utilizarse como agente de desulfuración y descarbonización, el gas puede ingresar primero al dispositivo de desulfuración para la desulfuración para producir fertilizante de sulfato de amonio, y el gas desulfurado puede ingresar al dispositivo de descarbonización para eliminar el dióxido de carbono en el gas, y puede producir fertilizante de bicarbonato de amonio. El gas descarbonizado puede incluir amoníaco libre, y el amoníaco libre en el gas puede ser absorbido con la solución ácida de sulfato de amonio y el líquido de lavado con agua ácida de la desulfuración a base de amoníaco.
