<p>A wet scrubber for absorbing a heavy metal from a gas stream, a liquor for said wet scrubber, and a power-plant comprising said wet scrubber are described. The wet scrubber has a liquor containing an oxidizer in ionic liquid. Optionally, the oxidizer has, in pure state, high vapor pressure, and in the ionic liquid, the oxidizer forms a complex that has a much lower vapor pressure. In a preferred embodiment, the liquor is substantially free of any ligand that binds to the metal to be absorbed by the liquor.</p> |
