Abstract

A ferrous sulfide suspension that includes at least FeSm and Al(OH)3 and which can be used to reduce mercury emissions in flue gases. Through a combination of complex chemical reactions, precipitation, co-precipitation, and surface adsorption the ferrous sulfide suspension of the present invention effectively removes mercury from gaseous streams while concurrently preventing mercury re-emission.
