# 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 II: Secondary or end-of-pipe techniques, such as:

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

Technique
Description
Applicability
(i)
Selective catalytic reduction (SCR)
See Section 1.20.2
Generally applicable for new units.
For existing units, the applicability may be constrained due to the requirements for significant space and optimal reactant injection
(ii)
Selective non-catalytic reduction (SNCR)
See Section 1.20.2
Generally applicable for new units.
For existing units, the applicability may be constrained by the requirement for the temperature window and the residence time to be reached by reactant injection
(iii)
Low temperature oxidation
See Section 1.20.2
The applicability may be limited by the need for additional scrubbing capacity and by the fact that ozone generation and the associated risk management need to be properly addressed.
The applicability may be limited by the need for additional waste water treatment and related cross-media effects (e.g. nitrate emissions) and by an insufficient supply of liquid oxygen (for ozone generation).
For existing units, the applicability of the technique may be limited by space availability
(iv)
SNOX combined technique
See Section 1.20.4
Applicable only for high flue-gas (e.g. > 800 000 Nm3/h) flow and when combined NOX and SOX abatement is needed
