Method for removal of nitrogen oxides from stationary combustion sources

摘要

A method for removing NOX from gas streams emanating from stationary combustion sources and manufacturing plants utilizes the injection of hydrogen peroxide into the gas stream for rapid gas-phase oxidation of NO to NO2 and water-soluble nitrogen acids HNO2 and HNO3. The nitrogen acids may be removed from the oxidized gas stream by wet scrubbing or by contact with a particulate alkaline material to form a nitrite/nitrate salt.
