# Commission Implementing Decision of 26 March 2013 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for the production of cement, lime and magnesium oxide (notified under document C(2013) 1728) (Text with EEA relevance) (2013/163/EU), Division 20

Extent: E+W+S+N.I.

When SNCR is used, BAT is to achieve efficient NOx reduction, while keeping the ammonia slip as low as possible, by using the following technique:
Technique
a
To apply an appropriate and sufficient NOx reduction efficiency along with a stable operating process
b
To apply a good stoichiometric distribution of ammonia in order to achieve the highest efficiency of NOx reduction and to reduce the NH3 slip
c
To keep the emissions of NH3 slip (due to unreacted ammonia) from the flue-gases as low as possible taking into account the correlation between the NOx abatement efficiency and the NH3 slip
