    摘要： A process of treating a gas stream containing at least one mercury compound or species, the process comprising: applying a composition into said gas stream ahead of a particulate matter collection device, wherein said composition contains a compound having the following formula (SiO2)x(OH)yMzSaF, wherein (i) SiO2 is an optional component; (ii) M comprises at least one of the following metal or metalloid cations: boron, magnesium, aluminum, calcium, titanium, vanadium, manganese, iron, cobalt, nickel, copper, zinc, zirconium, molybdenum, palladium, silver, cadmium, tin, platinum, gold, and bismuth; (iii) S comprises a sulfur-based species selected from at least one of the following: sulfide salts, dithiocarbamates, polymer-based dithiocarbamates, and polysulfide salts; (iii) F is an optional component and if present comprises at least one of the following: a functionalized organosilane, a sulfur-containing organosilane, an amine-containing organosilane, and an alkyl-containing organosilane at a surface area coverage of 0.01-100%; (iv) the molar ratio of y/x is equal to about 0.01 to about 0.5 and the molar ratio of x/z is equal to about 0.1 to about 300 if SiO2 is present, and if SiO2 is absent X is 0 and Z is 1; and (v) the molar ratio of a/z is about 0.5 to about 5.

    摘要： A scrubber for removing pollutant compounds from a gas stream. At least one gas channel introduces the gas stream to a lower portion of the scrubber. An inlet chamber directs the gas stream upwards to form a vertical gas stream. A constriction section has a vertical axis of symmetry and includes a centrally arranged venturi nozzle, and is above and in flow connection with an upper end of the inlet chamber for accelerating the vertical gas stream. A reaction chamber is arranged above and in flow connection with the constriction section. A reagent in the reaction chamber converts pollutant compounds in the gas stream to reaction products. A discharge channel in flow connection with the reaction chamber discharges gas and particles including the reaction products from the reaction chamber. A particle separator separates particles from the gas. A return channel recycles a portion of the particles to the reaction chamber.

    摘要： A method for removing contaminants from the combustion gases generated by the incineration of waste. Air is injected into an incineration device along with a fuel and is supplemented by a oxygen feed. The resulting combustion waste gas stream contains contaminants such as nitrogen oxides and is quenched, then fed to a reaction zone where it will contact ozone for a predetermined period of time. The thus treated combustion waste gas stream can be fed to a scrubber assembly where the reaction products formed by the reaction of ozone and the contaminants are removed.
