Activated Carbon Injection is the most established commercial technology for reducing mercury emissions from coal-fired boiler flue gases. It is a system in which Powdered Activated Carbon (PAC) is pneumatically injected from a storage silo into the flue gas ductwork where it then adsorbs mercury and is collected along with fly ash in the plant’s particulate collector.
- Capable of greater than 90% control
- ACI can be used as a stand-alone technology for Hg control or a key part of an integrated solution
- Equipment requires a small footprint, and can be easily integrated into your facility’s current APC configuration
- Effective across a wide range of coals and plant configurations
