Division 1.10.1.4 Mercury emissions
United Kingdom
| Technique | Description |
|---|---|
| Activated carbon adsorption | This process is based on the adsorption of mercury onto the activated carbon. When the surface has adsorbed as much as it can, the adsorbed content is desorbed as part of the regeneration of the adsorbent |
| Selenium adsorption | This process is based on the use of selenium-coated spheres in a packed bed. The red amorphous selenium reacts with the mercury in the gas to form HgSe. The filter is then treated to regenerate the selenium. |
