Commission Implementing Decision of 26 March 2013 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for the production of cement, lime and magnesium oxide (notified under document C(2013) 1728) (Text with EEA relevance) (2013/163/EU)

1.4.4.4 SO_x emissions U.K.

65. In order to reduce the emissions of SO_x from the flue-gases of kiln firing processes, BAT is to use a combination of the following primary and secondary techniques: U.K.

a A description of the measure/technique is provided in Section 1.7.2
	Technique	Applicability
a	Process optimisation techniques	Generally applicable
b	Selecting fuels with a low sulphur content	Generally applicable subject to availability of low sulphur fuels which may be impacted by the energy policy of the Member State. The selection of fuel also depends on the quality of the final product, technical possibilities and economic considerations
c	A dry absorbent addition technique (sorbent addition into the flue gas stream such as reactive MgO grades, hydrated lime, activated carbon, etc.), in combination with a filtera	Generally applicable
d	Wet scrubbera	The applicability may be limited in arid areas by the large volume of water necessary and the need for waste water treatment and the related cross-media effects

BAT-associated emission levels U.K.

See Table 15.

BAT-associated emission levels for SO_x from flue-gases of kiln firing processes in the magnesia industry

a The BAT-AELs depend on the content of sulphur in the raw materials and fuels. The lower end of the range is associated with the use of raw materials with low sulphur content and the use of natural gas; the upper end of the range is associated with the use of raw materials with higher sulphur content and/or the use of sulphur-containing fuels.
b Cross-media effects should be taken into account to assess the best combination of BAT to reduce SOx emissions.
c When a wet scrubber is not applicable, BAT-AELs depend on the sulphur content of raw materials and fuels. In this case, the BAT-AEL is < 1 500 mg/Nm3 while ensuring a SOX emissions removal efficiency of at least 60 %.
Parameter	Unit	BAT-AELa b(daily average value or average over the sampling period (spot measurements for at least half an hour))
