BAT-associated emission levels: See Table 8.
BAT-associated emission levels for dust, BaP (as an indicator of PAH) and fluoride emissions to air from a baking plant in an anode production plant integrated with a primary aluminium smelter
The associated monitoring is in BAT 10.
BAT-associated emission levels: See Table 9.
BAT-associated emission levels for dust, BaP (as an indicator of PAH) and fluoride emissions to air from a baking plant in a stand-alone anode production plant
The associated monitoring is in BAT 10.
Generally applicable to new plants and major upgrades. The applicability may be limited due to water quality and/or product quality requirements.
There may be restrictions on applicability depending on the ash content of the carbon dust.
