Division BAT 57: In order to reduce emissions of organic compounds to air, BAT is to use technique d given below for waste gas from the cumene oxidation unit. For any other individual or combined waste gas streams, BAT is to use one or a combination of the techniques given below.
United Kingdom
| Technique | Description | Applicability | |
|---|---|---|---|
| a. | Send the waste gas stream to a combustion unit | See BAT 9 | Only applicable where there are available uses for the waste gas as gaseous fuel |
| b. | Adsorption | See Section 12.1 | Generally applicable |
| c. | Thermal oxidiser | See Section 12.1 | Generally applicable |
| d. | Regenerative thermal oxidiser (RTO) | See Section 12.1 | Generally applicable |
Table 7.1
BAT-AELs for emissions of TVOC and benzene to air from the production of phenol
| Parameter | Source | BAT-AEL(daily average or average over the sampling period)(mg/Nm3, no correction for oxygen content) | Conditions |
|---|---|---|---|
| Benzene | Cumene oxidation unit | < 1 | The BAT-AEL applies if the emission exceeds 1 g/h |
| TVOC | 5–30 | — |
The associated monitoring is in BAT 2.
