Abstract

Hg is removed from waste gases contng. dust and possibly other gaseous pollutants by spraying aq. Na2S4 soln. into the waste gas (2) and then passing it through a bed forming filter (3). Pref. before spraying in the Na2S4 soln., dust is removed from the waste gas using an electrostatic filter (1). The concn. of Na2S4 soln. is pref. 10-20%.
