20150283500 | Solution-Based Mercury Capture - A mercury capture system and method that includes the equipment for and the production of a mercury-sorbent metal sulfide in a flue gas conduit of a coal fired power plant. The system can include transition metal salt solution injection and sulfur solution injection apparati that can introduce transition metal salt solution and sulfur solution droplets (individually or as a co-injection) into the flue gas stream. The method can include the introduction (individually or as a co-injection) of a copper salt, an iron salt, and a sulfur compound into the flue gas stream, wherein the mercury-sorbent metal sulfide can be manufactured and reacted with mercury in the flue gas. | 10-08-2015 |
