# Commission Implementing Decision of 9 October 2014 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions, for the refining of mineral oil and gas (notified under document C(2014) 7155) (Text with EEA relevance) (2014/738/EU), Division I: Primary or process-related techniques, such as:

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

Technique
Description
Applicability
Process optimisation and use of promoters or additives
(i)
Process optimisation
Combination of operating conditions or practices aimed at reducing NOX formation, e.g. lowering the excess oxygen in the flue-gas in full combustion mode, air staging of the CO boiler in partial combustion mode, provided that the CO boiler is appropriately designed
Generally applicable
(ii)
Low-NOX CO oxidation promoters
Use of a substance that selectively promotes the combustion of CO only and prevents the oxidation of the nitrogen that contains intermediates to NOX: e.g. non-platinum promoters
Applicable only in full combustion mode for the substitution of platinum-based CO promoters.
Appropriate distribution of air in the regenerator may be required to obtain the maximum benefit
(iii)
Specific additives for NOX reduction
Use of specific catalytic additives for enhancing the reduction of NO by CO
Applicable only in full combustion mode in an appropriate design and with achievable oxygen excess. The applicability of copper-based NOX reduction additives may be limited by the gas compressor capacity
