Division BAT 34
United Kingdom
In order to reduce diffuse emissions from electrolysis cells, BAT is to use one or a combination of the techniques given below.
| Technique | Applicability | |
|---|---|---|
| a | Addition of surfactants to the electrowinning cells | Generally applicable |
| b | Use covers or a hood to collect and transfer the emissions to an abatement system | Only applicable for electrowinning cells or refining cells for low-purity anodes. Not applicable when the cell needs to remain uncovered to maintain the cell temperature at workable levels (approximately 65 °C) |
| c | Closed and fixed pipelines for transferring the electrolyte solutions | Generally applicable |
| d | Gas extraction from the washing chambers of the cathode stripping machine and anode scrap washing machine | Generally applicable |
