Método y aparato para separar mercurio a partir de gases de la combustión de combustibles sólidos

摘要

A method is described for removing mercury from the products of fuel conversion (18) comprising injecting activated carbon (66) into contact with the products of fuel conversion at a contact location upstream of an air heater (22) where a temperature of the products of fuel conversion is greater than 600°F (316°C), whereupon the activated carbon adsorbs mercury; and removing the activated carbon having mercury adsorbed thereon at a collection location (24,136) where the temperature of the products of fuel conversion is less than 370°F (188°C).
