Division BAT 28 In order to reduce emissions of polychlorinated dibenzodioxins/furans (PCDD/F) to air from the catalytic reforming unit, BAT is to use one or a combination of the techniques given below.
United Kingdom
| Technique | Description | Applicability |
|---|---|---|
| (i) Choice of the catalyst promoter | Use of catalyst promoter in order to minimise polychlorinated dibenzodioxins/furans (PCDD/F) formation during regeneration. See Section 1.20.7 | Generally applicable |
| (ii) Treatment of the regeneration flue-gas | ||
| a. Regeneration gas recycling loop with adsorption bed | Waste gas from the regeneration step is treated to remove chlorinated compounds (e.g. dioxins) | Generally applicable to new units. For existing units the applicability may depend on the current regeneration unit design |
| b. Wet scrubbing | See Section 1.20.3 | Not applicable to semi-regenerative reformers |
| c. Electrostatic precipitator (ESP) | See Section 1.20.1 | Not applicable to semi-regenerative reformers |
