Process for reducing nitrogen oxides |
| abstract |
A process for reducing nitrogen oxides in an exhaust stream, comprises providing a first composition comprising urea and water, a second composition comprising ammonium carbamate and an exhaust stream (10) comprising nitrogen oxides. The second composition is introduced into the exhaust stream when the exhaust stream has a temperature below a threshold temperature and the first composition is introduced into the exhaust stream when the exhaust stream has a temperature at or above the threshold temperature. The ammonium carbamate may be produced in situ from the first composition. Also disclosed is a process for the preparation of ammonium carbamate characterised by a first reservoir (12) and a second reservoir (24). Also disclosed is an apparatus for delivering first and second compositions to an exhaust stream characterised by means, such as an injector for delivering a portion of a first composition and means for delivering a second composition. The process may be used to produce ammonium carbamate for reducing nitrogen oxides ( NOx ) in an exhaust stream from a combustor such as a vehicle. |
