Abstract
Sorbent compositions, comprising a solid sorbent, a dispersive agent, and optionally a capture agent for enhanced wet-Flue Gas Desulfurization (wFGD) or wet scrubber unit function in a flue gas pollutant control stream is disclosed. The sorbent composition may include a sorbent with a dispersive agent, designed to enhance the dispersion of the sorbent in an aqueous sorption liquid of a wet scrubber unit, and therefore may be especially useful in EGU or industrial boiler flue gas streams that include one or more wet scrubber units. The sorbent composition may also include a capture agent useful in sequestering mercury and bromine, as well as other contaminants that may include arsenic, selenium and nitrates.
Claims15
A wet scrubber unit disposed in a flue gas train, the wet scrubber unit containing an aqueous sorption liquid, wherein the aqueous sorption liquid comprises:
- water;
- an alkaline compound dispersed in the water;
- a solid sorbent;
- and
- a dispersive agent,
- wherein the solid sorbent is dispersed throughout the aqueous sorption liquid.
