Abstract
A process for removing contaminants from a waste gas stream comprises treating the waste gas stream to remove at least one of SOand NOand to obtain a lean stream having a reduced level of at least one of SOand NOand, contacting the lean gas stream with a mercury absorbent solution comprising permanganate to remove mercury vapour and to obtain a mercury lean stream and a mercury rich absorbent solution. The mercury rich absorbent solution may be subsequently treated on a batch basis to remove precipitated manganese dioxide and obtain a solution containing mercury ions.
