# 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
To avoid potential fouling downstream, additional filtering might be required upstream of the SCR.
For existing units, the applicability may be limited by space availability
(ii)
Selective non-catalytic reduction (SNCR)
See Section 1.20.2
For partial combustion FCCs with CO boilers, a sufficient residence time at the appropriate temperature is required.
For full combustion FCCs without auxiliary boilers, additional fuel injection (e.g. hydrogen) may be required to match a lower temperature window
(iii)
Low temperature oxidation
See Section 1.20.2
Need for additional scrubbing capacity.
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).
The applicability of the technique may be limited by space availability
