Division BAT 89
United Kingdom
In order to reduce gaseous emissions to air from wet milling and leaching from the salt slag recovery process, BAT is to use one or a combination of the techniques given below.
| Descriptions of the techniques are given in Section 1.10. | |
| Techniquef1 | |
|---|---|
| a | Activated carbon injection |
| b | Afterburner |
| c | Wet scrubber with H2SO4 solution |
BAT-associated emission levels: See Table 21.
