Method and Device for Treating Exhaust Gases

摘要

The present invention relates to a method for treating exhaust gases containing nitrogen oxide from technical processes, such as fume gases, for the purpose of removing or precipitationg the nitrogen oxide and/or for the purpose of reducing the nitrogen oxide content, in particular by chemically reducing the nitrogen oxide.

主权项

1. A method for the treatment of nitrogen oxide-containing exhaust gases from technical processes, such as flue gases, for the purposes of removing and/or separating off the nitrogen oxides and/or for the purposes of reducing the nitrogen oxide content, in particular a method for the denitrification of exhaust gases from large technical installations,
characterized (a) in that, in a first method step, the exhaust gases are selectively cooled; and (b) in that, in a simultaneous and/or subsequent second method step, the nitrogen oxides are removed and/or separated off from the exhaust gases.
