# Commission Implementing Decision (EU) 2019/2010 of 12 November 2019 establishing the best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for waste incineration (notified under document C(2019) 7987) (Text with EEA relevance), Division 1.5.2.2: Emissions of HCl, HF and SO2

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

BAT 27. In order to reduce channelled emissions of HCl, HF and SO2 to air from the incineration of waste, BAT is to use one or a combination of the techniques given below.
Technique
Description
Applicability
(a)
Wet scrubber
See Section 2.2
There may be applicability restrictions due to low water availability, e.g. in arid areas.
(b)
Semi-wet absorber
See Section 2.2
Generally applicable.
(c)
Dry sorbent injection
See Section 2.2
Generally applicable.
(d)
Direct desulphurisation
See Section 2.2.
Used for partial abatement of acid gas emissions upstream of other techniques.
Only applicable to fluidised bed furnaces.
(e)
Boiler sorbent injection
See Section 2.2.
Used for partial abatement of acid gas emissions upstream of other techniques.
Generally applicable.
BAT 28. In order to reduce channelled peak emissions of HCl, HF and SO2 to air from the incineration of waste while limiting the consumption of reagents and the amount of residues generated from dry sorbent injection and semi-wet absorbers, BAT is to use technique (a) or both of the techniques given below.
Technique
Description
Applicability
(a)
Optimised and automated reagent dosage
The use of continuous HCl and/or SO2 measurements (and/or of other parameters that may prove useful for this purpose) upstream and/or downstream of the FGC system for the optimisation of the automated reagent dosage.
Generally applicable.
(b)
Recirculation of reagents
The recirculation of a proportion of the collected FGC solids to reduce the amount of unreacted reagent(s) in the residues.
The technique is particularly relevant in the case of FGC techniques operating with a high stoichiometric excess.
Generally applicable to new plants.
Applicable to existing plants within the constraints of the size of the bag filter.
Table 5
BAT-associated emission levels (BAT-AELs) for channelled emissions to air of HCl, HF and SO2 from the incineration of waste
The lower end of the BAT-AEL range can be achieved when using a wet scrubber; the higher end of the range may be associated with the use of dry sorbent injection.
