Dustex - Model ACI - Activated Carbon Injection System - Brochure

An Activated Carbon Injection (ACI) System is an engineered system from which powdered activated carbon (PAC) is pneumatically injected from a storage silo into the flue gas ductwork. The PAC adsorbs the mercury from the flue gas and is then collected with the fly ash in the plant’s particulate collection device. ACI is the most established commercial technology for reducing mercury emissions from flue gases. It has been proven through numerous full-scale demonstrations to be the most effective, cost efficient way to reduce mercury emissions from most boilers. Depending upon the type of fuel being burned and the type of air pollution control equipment installed at the plant, ACI can reduce mercury emissions by more than 90%.
