ABSTRACT:
A system and method for controlling pollutant emissions in a cement manufacturing facility. The system comprises first and second particulate control devices in series and a sorbent supply provided downstream of the first particulate control device. Exhaust process gas from the pyroprocessing unit of the cement manufacturing facility is conveyed through the first particulate control device in order to remove at least a portion of the kiln dust within the exhaust process gas to form a de-dusted exhaust process gas. The kiln dust removed from the exhaust process gas may then be recycled back to the pyroprocessing unit for use in the kiln feed. The sorbent supply injects a sorbent for capturing pollutants into the de-dusted exhaust process gas upstream of the second particulate control device to form a treated gas. The spent sorbent containing the captured pollutants is removed from the treated gas within the second particulate control device to form a cleansed exhaust process gas.
