System and Method for Controlling and Reducing NOx Emissions

摘要

Methods and systems (10) are provided for reducing NO x 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 (16) to yield higher order N x O y molecules; and thereafter removing higher order N x O y molecules from the gas stream by solvent absorption or reaction (20). The system (10) may comprise a gas production source configured to produce a gas stream comprising NO x ; an oxidation catalyst (16) positioned downstream of the gas production source, wherein the oxidation catalyst (16) is configured to oxidize NO gas molecules in the gas stream to yield higher order N x O y molecules; and a removal device positioned downstream of the oxidation catalyst (16) configured to remove higher order N x O y molecules from the gas stream by solvent absorption or reaction (20).
