Division BAT 19 In order to prevent or reduce emissions to air from the press, BAT is to use in-duct quenching of collected press waste gas and an appropriate combination of the techniques given below.
United Kingdom
| Descriptions of the techniques are given in Section 1.4.1. | |||
| Technique | Main pollutants abated | Applicability | |
|---|---|---|---|
| a | Select resins with a low formaldehyde content | Volatile organic compounds | Applicability may be restricted, e.g. due to demands for a specific product quality |
| b | Controlled operation of the press with balanced press temperature, applied pressure and press speed | Volatile organic compounds | Applicability may be restricted, e.g. due to the operation of the press for specific product qualities |
| c | Wet scrubbing of collected press waste gases using Venturi scrubbers or hydrocyclones, etc.f1 | Dust, volatile organic compounds | Generally applicable |
| d | Wet electrostatic precipitator | Dust, volatile organic compounds | |
| e | Bioscrubber | Dust, volatile organic compounds | |
| f | Post-combustion as the last treatment step after application of a wet scrubber | Dust, volatile organic compounds | Applicability may be restricted for existing installations where a suitable combustion plant is not available |
Table 3
BAT-associated emission levels (BAT-AELs) for emissions to air from the press
| Parameter | Unit | BAT-AELs(average over the sampling period) |
|---|---|---|
| Dust | mg/Nm3 | 3–15 |
| TVOC | mg/Nm3 | 10–100 |
| Formaldehyde | mg/Nm3 | 2–15 |
The associated monitoring is in BAT 14.
