Abstract
Methods and systems are provided for reducing NOx emissions from a gas stream produced by a production source. The method may comprise oxidizing a substantial portion of NO gas present in the gas stream by contacting the gas stream with an oxidation catalyst to yield higher order NOmolecules; and thereafter removing higher order NOmolecules from the gas stream by solvent absorption or reaction. The system may comprise a gas production source configured to produce a gas stream comprising NOx; an oxidation catalyst positioned downstream of the gas production source, wherein the oxidation catalyst is configured to oxidize NO gas molecules in the gas stream to yield higher order NOmolecules; and a removal device positioned downstream of the oxidation catalyst configured to remove higher order NOmolecules from the gas stream by solvent absorption or reaction.
