Title: Process for nitrogen oxides reduction with minimization of the production of other pollutants

Patent ·
OSTI ID:7182752

This patent describes a process for reducing the concentration of nitrogen oxides in an effluent while minimizing the production of other pollutants. It comprises: 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 an ammonium salt of an organic acid having a carbon to nitrogen ratio of greater than 1:1 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; and 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.
