ABSTRACT:
Mercury is removed from a stream of hot waste gases by atomizing an aqueous liquid into the hot waste gases in the presence of fly ash suspended in the gas stream. Subsequently the fly ash is separated from the gas stream. A substantial part of the mercury originally present in the gas stream is absorbed or adsorbed by the fly ash so that the stream of the waste gas can safely be discharged to the atmosphere.
