# 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

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

BAT-associated emission levels: See Table 9, Table 10 and Table 11.
Table 9
BAT-associated emission levels for NOX emissions to air from a gas turbine
BAT-AEL refers to combined emissions from the gas turbine and the supplementary firing recovery boiler, where present.
For fuel with high H2 content (i.e. above 10 %), the upper end of the range is 75 mg/Nm3.
Parameter
Type of equipment
BAT-AEL(monthly average)mg/Nm3 at 15 % O2
NOX expressed as NO2
Gas turbine (including combined cycle gas turbine — CCGT) and integrated gasification combined cycle turbine (IGCC))
40-120
(existing turbine)
20-50
(new turbine)
The associated monitoring is in BAT 4.
Table 10
BAT-associated emission levels for NOX emissions to air from a gas-fired combustion unit, with the exception of gas turbines
For an existing unit using high air pre-heat (i.e. > 200 °C) or with H2 content in the fuel gas higher than 50 %, the upper end of the BAT-AEL range is 200 mg/Nm3.
Parameter
Type of combustion
BAT-AEL(monthly average)mg/Nm3
NOX expressed as NO2
Gas firing
30-150
for existing unit
30-100
for new unit
The associated monitoring is in BAT 4.
Table 11
BAT-associated emission levels for NOX emissions to air from a multi-fuel fired combustion unit with the exception of gas turbines
For existing units < 100 MW firing fuel oil with a nitrogen content higher than 0,5 % (w/w) or with liquid firing > 50 % or using air preheating, values up to 450 mg/Nm3 may occur.
The lower end of the range can be achieved by using the SCR technique.

Multi-fuel fired combustion unit
30-300
for existing unit
The associated monitoring is in BAT 4.
