Division 9.3 Emissions to air
United Kingdom
BAT 29. In order to reduce channelled emissions of organic compounds to air from meat smoking, BAT is to use one or a combination of the techniques given below.
| Technique | Description | |
|---|---|---|
| (a) | Adsorption | Organic compounds are removed from a waste gas stream by retention on a solid surface (typically activated carbon). |
| (b) | Thermal oxidation | See Section 14.2. |
| (c) | Wet scrubber | See Section 14.2. An electrostatic precipitator is commonly used as a pretreatment step. |
| (d) | Use of purified smoke | Smoke generated from purified primary smoke condensates is used to smoke the product in a smoke chamber. |
Table 18
BAT-associated emission level (BAT-AEL) for channelled TVOC emissions to air from a smoke chamber
| The lower end of the range is typically achieved when using adsorption or thermal oxidation. | ||
| The BAT-AEL does not apply when the TVOC emission load is below 500 g/h. | ||
| Parameter | Unit | BAT-AEL(average over the sampling period) |
|---|---|---|
| TVOC | mg/Nm3 | 3-50 f1 f2 |
The associated monitoring is given in BAT 5.
