Abstract
A process for removing mercury from a gaseous process stream. The process involves contacting a mercury-containing gaseous process stream with a regenerable mercury scavenger solution to form a treated stream having a reduced mercury content as compared to the mercury-containing gaseous process stream and a used scavenger solution having an increased mercury content. The regenerable mercury scavenger solution contains an oxidizing agent such as nitric acid, a complexing agent such as oxygen-containing agents and/or thiol and a solvent, for example, a mixture of methanol and water.
