Division 13.3 Emissions to air
United Kingdom
BAT 36. In order to prevent or reduce channelled dust emissions to air from beet pulp drying, BAT is to use one or a combination of the techniques given below.
| Technique | Description | Applicability | |
|---|---|---|---|
| (a) | Use of gaseous fuels | See Section 14.2. | May not be applicable due to the constraints associated with the availability of gaseous fuels. |
| (b) | Cyclone | Generally applicable. | |
| (c) | Wet scrubber | ||
| (d) | Indirect drying (steam drying) of beet pulp | See BAT 35b. | May not be applicable to existing plants due to the need for a complete reconstruction of the energy facilities. |
| (e) | Solar drying of beet pulp | See BAT 35c. | May not be applicable due to local climatic conditions and/or lack of space. |
| (f) | Low-temperature (pre)drying of beet pulp | See BAT 35e. | Generally applicable. |
Table 30
BAT-associated emission level (BAT-AEL) for channelled dust emissions to air from beet pulp drying in the case of high-temperature drying (above 500 °C)
| Parameter | Unit | BAT-AEL (average over the sampling period) | Reference oxygen level (OR) | Reference gas condition |
|---|---|---|---|---|
| Dust | mg/Nm3 | 5-100 | 16 vol-% | No correction for water content |
The associated monitoring is given in BAT 5.
BAT 37. In order to reduce channelled SOX emissions to air from high-temperature beet pulp drying (above 500 °C), BAT is to use one or a combination of the techniques given below.
| Technique | Description | Applicability | |
|---|---|---|---|
| (a) | Use of natural gas | — | May not be applicable due to the constraints associated with the availability of natural gas. |
| (b) | Wet scrubber | See Section 14.2. | Generally applicable. |
| (c) | Use of fuels with low sulphur content | — | Only applicable when natural gas is not available. |

BAT-associated emission level (BAT-AEL) for channelled SOX emissions to air from beet pulp drying in the case of high-temperature drying (above 500 °C) when natural gas is not used
| When using exclusively biomass as a fuel, emission levels are expected to be at the lower end of the range. | ||||
| Parameter | Unit | BAT-AEL(average over the sampling period) f1 | Reference oxygen level (OR) | Reference gas condition |
|---|---|---|---|---|
| SOX | mg/Nm3 | 30-100 | 16 vol-% | No correction for water content |
The associated monitoring is given in BAT 5.
