Abstract: 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.

Abstract: Methods of controlling bacterial, yeast, and/or mold contamination of edible fruits or vegetables comprise applying thereto an aqueous microbiocidal composition formed from water and (A) at least one component selected from (I) a solid-state microbiocidal compound having at least one bromine atom per molecule; (II) an aqueous solution/slurry of a compound of (I); (III) a concentrated aqueous composition having an active bromine content of at least 50,000 ppm derived from water and (i) BrCl or BrCl and Br2 and (ii) overbased alkali metal sulfamate, where the relative proportions of (i) and (ii) give an atom ratio of nitrogen to active bromine greater than 0.93, and where the pH of the composition is greater than 7; and (IV) a solid-state composition formed by dewatering a composition of (III).

Abstract: Disclosed are sorbents having superior water leachability performance characteristics especially when used as sorbents in semi-dry (CDS), high moisture (SDA), and fully wet SO2 scrubbers. Also disclosed are methods for the production of such performance-enhanced sorbents, and methods for the use of such sorbents in the removal of mercury and possibly one or more other heavy metals or other contaminants from various gaseous streams. The sorbents are carbonaceous substrates treated with a bromine-containing compound, especially gaseous bromine, and with at least one organic compound that contains at least one olefinic double bond.

Abstract: Activated carbon is rendered more thermally stable by exposure to a non-halogenated additive, and optionally to a halogen and/or a halogen-containing compound. Such treated carbon is suitable for use in mitigating the content of hazardous substances in flue gases, especially flue gases having a temperature within the range of from about 100° C. to about 420° C.

Abstract: Ultraviolet light stabilized antimicrobial compositions are formed from (A) and (B). (A) is (I) a solid-state microbiocidal compound having at least one bromine atom in the molecule; (II) an aqueous solution or slurry of (I); (III) is a concentrated aqueous antimicrobial composition having a dissolved active bromine content derived from (i) BrCl or BrCl and Br2 and (ii) overbased alkali metal sulfamate and/or sulfamic acid, alkali metal base, and water, (IV) solids made by dewatering a composition of (III). (B) is a ultraviolet light degradation-inhibiting amount of up to one part by weight of ascorbic acid, dehydroascorbic acid and/or an edible water-soluble salt/ester thereof per part by weight of bromine in the selected antimicrobial composition. Preparation and uses of such compositions are described. Methods of controlling contamination of seafood and seafood products by pathogens are also described.

Abstract: Methods and containers suitable for reducing or eliminating bacteria such as Salmonella© in eggs for human consumption are provided. Such methods and containers use at teas! one N,N-dihal?-5,5-diaiky!hydant?in in which each of the alky! groups Independently comprises from 1 to about 6 carbon atoms.

Abstract: Compositions and methods suitable for killing bacteria and controlling biofilms comprising one or more microorganisms are provided wherein molecules capable of emulating cell-to-cell signal molecules of the microorganisms are utilized.
