# Commission Implementing Decision (EU) 2017/2117 of 21 November 2017 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the production of large volume organic chemicals (notified under document C(2017) 7469) (Text with EEA relevance), Division 2.1.1: BAT-AELs for emissions to air from a lower olefins cracker furnace

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

Table 2.1
BAT-AELs for emissions to air of NOX and NH3 from a lower olefins cracker furnace
Where the flue gases of two or more furnaces are discharged through a common stack, the BAT-AEL applies to the combined discharge from the stack.
The BAT-AELs do not apply during decoking operations.
No BAT-AEL applies for CO. As an indication, the CO emission level will generally be 10–50 mg/Nm3 expressed as a daily average or an average over the sampling period.
The BAT-AEL only applies when SCR or SNCR are used.
Parameter
BAT-AELs (daily average or average over the sampling period)(mg/Nm3, at 3 vol-% O2)
New furnace
Existing furnace
NOX
60–100
70–200
NH3
< 5–15
The associated monitoring is in BAT 1.
