Method for reducing nitrogen oxide emissions in industrial process

One embodiment of the invention provides novel methods for reducing the generation of NOx emissions in industrial processes. These methods include the steps of: feeding a reaction feed mixture to a reaction vessel having an inlet and an outlet; producing a reaction product including a hot mixed gas...

Zusammenfassung:	One embodiment of the invention provides novel methods for reducing the generation of NOx emissions in industrial processes. These methods include the steps of: feeding a reaction feed mixture to a reaction vessel having an inlet and an outlet; producing a reaction product including a hot mixed gas stream in the reaction vessel; producing a cooled mixed gas stream by directing the hot mixed gas stream to a heat exchanger system; separating the cooled mixed gas stream into a cooled crude product stream and a cooled waste stream; producing a preheated waste stream by directing the cooled waste stream to a heat exchanger system; and incinerating the preheated waste stream by directing it to an incinerator. Upon incineration of the preheated waste stream, a decreased amount of NOx emissions is produced when compared to the amount of NOx emissions which would have been produced by incinerating the cooled waste stream.
