  • Publication number: 20200129924
    Abstract: A sorbent composition that is useful for injection into a flue gas stream of a coal burning furnace to efficiently remove mercury from the flue gas stream. The sorbent composition may include a sorbent with an associated ancillary catalyst component that is a catalytic metal, a precursor to a catalytic metal, a catalytic metal compound or a precursor to a catalytic metal compound. Alternatively, a catalytic metal or metal compound, or their precursors, may be admixed with the coal feedstock prior to or during combustion in the furnace, or may be independently injected into a flue gas stream. A catalytic promoter may also be used to enhance the performance of the catalytic metal or metal compound.

  • Patent number: 10421037
    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.

  • Patent number: 10159928
    Abstract: Sorbent compositions including sorbent particles of a small particle sized sorbent with increased pneumatic conveyance properties. The sorbent compositions have relatively small median particle size and have a controlled particle size distribution (PSD). Specifically, the sorbent compositions include a relatively small percentage of very fine particles, such as a small percentage of particles having a particle size of not greater than about 5 ?m. The sorbent compositions are particularly useful for the treatment of a flue gas stream to remove mercury from the flue gas stream.

  • Patent number: 10137403
    Abstract: A sorbent composition such as for the removal of a contaminant species from a fluid stream, a method for manufacturing a sorbent composition and a method for the treatment of a flue gas stream to remove heavy metals such as mercury (Hg) therefrom. The sorbent composition includes a porous carbonaceous sorbent such as powdered activated carbon (PAC) and a solid particulate additive that functions as a flow-aid to enhance the pneumatic conveyance properties of the sorbent composition. The solid particulate additive may be a flake-like material, for example a phyllosilicate mineral or graphite.

  • Publication number: 20140191157
    Abstract: Compositions and method useful for removal of mercury from a flue gas stream with relatively high concentrations of acid gas precursors and/or acid gases. The method includes contacting the flue gas stream with a sorbent composition comprising a sorbent material and a multi-functional agent, where the multi-functional agent includes a compound having a metal of valency 3 or higher. The multi-functional agent may be an inorganic salt, wherein either the cation or anion of the salt comprises a metal selected from Group 3 to 14 metal, such as aluminum. A halogen such as in the form of a halide salt that helps facilitate the oxidation of elemental mercury into its oxidized form may be present in the sorbent composition.

The method includes contacting the flue gas stream with a multi-functional agent, where the multi-functional agent includes a salt having a cation of valency 3 or higher. A composition comprises a (1) sorbent material such as powdered activated carbon which will ultimately capture and sequester oxidized mercury, (2) a multi-functional agent that protects the sorbent core from unfavorable reaction conditions or inhibitors, oxidizes or helps catalyze the oxidation of elemental mercury, and/or amalgamates with elemental mercury to make it easier to capture, among other benefits, and optionally (3) a halogen such as in the form of a halide salt that helps facilitate the oxidation of elemental mercury into its oxidized form.
