Systemfor Controlling and Reducing NOx Emissions

A system includes a gas production source (12) configured to produce a gas stream (14) comprising nitrogen oxides (NO x ) (16) and a hydrocarbon injector (18) disposed downstream of the gas production source (12) and configured to inject a hydrocarbon into the gas stream (14). The hydrocarbon is con...

Beschreibung
Zusammenfassung:	A system includes a gas production source (12) configured to produce a gas stream (14) comprising nitrogen oxides (NO x ) (16) and a hydrocarbon injector (18) disposed downstream of the gas production source (12) and configured to inject a hydrocarbon into the gas stream (14). The hydrocarbon is configured to oxidize molecules of the NO x (16) in the gas stream (14) to produce a higher order compound of nitrogen and oxygen (N y O z ) (22). The system also includes a removal device (24) disposed downstream of the hydrocarbon injector (18). The removal device (24) is configured to remove the N y O z (22) from the gas stream via absorption or reaction.
