Abstrakt

The sources of N2O emissions are reviewed and compared with the N2O formation in HNO3 production plants. The current and new methods of controlling emissions from HNO3 production are discussed. The methods involve homogeneous decomposition of N2O in the combustion burner zone for oxidation of ammonia and nonselective catalytic reduction of NOx and N2O in the tail gases. The latter methods include catalytic decomposition of N2O in the ammonia oxidation chamber and that of NOx and N2O located at the inlet to the expansion turbine.
