Process for nitrogen oxides reduction with minimization of the production of other pollutants
This patent describes a process for reducing the concentration of nitrogen oxides in an effluent which is at a temperature below about 1450 {degrees}F while minimizing the production of other pollutants. The process comprising: determining the condition of the effluent which exists at a location for introduction of a treatment agent; effecting a treatment regimen which comprises introducing a treatment agent comprising a hydrocarbon into the effluent to reduce the nitrogen oxides concentration in the effluent under the determined effluent conditions while minimizing the production of other pollutants; monitoring the condition of the effluent until a significant alteration in the condition of the effluent is observed; adjusting the treatment regimen by varying at least one of the following parameters: dilution and introduction rate of the hydrocarbon treatment agent; composition of the hydrocarbon treatment agent; and relative presence of the components of the hydrocarbon treatment agent, to effect an adjusted treatment regimen. Wherein the adjusted treatment regimen operates under conditions effective to reduce the nitrogen oxides concentration in the effluent under the altered effluent conditions.
