Abstract

Ésta proporciona métodos para reducir las emisiones de mercurio de una planta de cemento que comprende al menos un horno, un dispositivo de recolección de partículas, partículas recolectadas, una corriente de gas de escape, un calentador, y un depurador de mercurio, donde el calentador y el depurador de mercurio se encuentran corriente arriba del horno. Los métodos comprenden dirigir las partículas recolectadas a través del calentador, para formar especies de mercurio volatilizadas de las partículas recolectadas; dirigir las partículas recolectadas desde el calentador hacia abajo con dirección al horno; y dirigir las especies de mercurio volatilizadas hacia el depurador de mercurio. La corriente de gas de escape sale del dispositivo de recolección de partículas y no se dirige hacia el calentador. Los pasos opcionales incluyen inyectar un adsorbente de mercurio en uno o más puntos entre el horno y el dispositivo de recolección de partículas.
