Division 1.3.2 Emissions to air
United Kingdom
- BAT 34In order to prevent and reduce SO2 emissions, BAT is to collect all highly concentrated SO2-gas streams from acid liquor production, digesters, diffusers, or blow tanks and to recover the sulphur components.
- BAT 35In order to prevent and reduce diffuse sulphur-containing and odorous emissions from washing, screening, and evaporators, BAT is to collect these weak gases and to apply one of the techniques given below.
- BAT 36In order to reduce NOx emissions from a recovery boiler, BAT is to use an optimised firing system including one or a combination of the techniques given below.
- BAT 37In order to reduce dust and SO2 emissions from a recovery boiler, BAT is to use one of the techniques given below and to limit ‘acid operation’ of the scrubbers to the minimum required to ensure their proper functioning.
