Injection of sorbents in ductwork feeding wet scrubbers for mercury emission control

摘要

Methods and systems are described for more effectively sequestering or removing mercury from flue gases. This is accomplished by feeding an adsorbent into the flow of flue gas in ductwork leading into a scrubber housing containing a wet scrubber composition and providing a residence time sufficient to enable the mercury to be sequestered by the adsorbent.
