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.
Claims25
A sorbent composition for enhanced removal of contaminants from the aqueous sorption liquid of a wet scrubber unit, the sorbent composition comprising:
- a carbonaceous solid sorbent comprising activated carbon having a median particle size of not greater than about 100 micron and a sum of micropore volume plus mesopore volume of at least about 0.20 cc/g, and
- a dispersive agent disposed on a surface of the carbonaceous solid sorbent,
- wherein the sorbent composition is configured to be dispersed within the aqueous sorption liquid of a wet scrubber unit.
