3, which can be extremely damaging due to its acidic properties. [6] Zeolite catalysts have the potential to operate at substantially higher temperature than base metal catalysts; they can withstand prolonged operation at temperatures of 900 K (627 °C) and transient conditions of up to 1120 K (847 °C). Zeolites also have a lower potential for SO
This emulsification can either be made in-line (unstabilized) just before the injection or as a drop-in fuel with chemical additives for long-term emulsion stability (stabilized). Excessive water addition facilitates hot corrosion, which is the primary reason why dry low- NO x technologies are favored today besides the requirement of a more ...
The SNOX process is a very energy-efficient way to convert the NOx in the flue gas into nitrogen and the SOx into concentrated sulfuric acid of commercial quality without using any absorbents and without producing waste products or waste water.
Selective non-catalytic reduction (SNCR) is a method to lessen nitrogen oxide emissions in conventional power plants that burn biomass, waste and coal.The process involves injecting either ammonia or urea into the firebox of the boiler at a location where the flue gas is between 1,400 and 2,000 °F (760 and 1,090 °C) to react with the nitrogen oxides formed in the combustion process.

Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. An early application of a carbon dioxide scrubber was in the submarine the Ictíneo I, in 1859; a role for which they continue to be used today ...
Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, or factitious air, among others, [4] is a chemical compound, an oxide of nitrogen with the formula N 2 O .
The G. G. Allen Steam Station scrubber (North Carolina) Flue-gas desulfurization ( FGD ) is a set of technologies used to remove sulfur dioxide ( SO 2 ) from exhaust flue gases of fossil-fuel power plants , and from the emissions of other sulfur oxide emitting processes such as waste incineration , petroleum refineries, cement and lime kilns.
