Abstract
1342222 Mercury removal from gas streams DET NORSKEZINKKOMPANI A/S 14 Jan 1972 [14 Jan 1971] 1881/72 Heading C1A A process for the removal of mercury from tail gas streams from the combustion or roasting of ores or electrolysis cells, comprises washing the gases with sulphuric acid of at least 50% concentration at a temperature of 60 C. to 180 C., wherein the washing acid and the gases contain chlorine and/or chlorine compounds in such an amount that the atomic ratio C2/Hg is at least 1 : 1 thereby converting practically all the mercury and other mercury compounds to mercury chlorides which are separated by condensation during cooling of the gas stream. If the gas contains insufficient chlorine, chlorine or chlorine compound may be added to the washing liquid or preferably chlorine or gaseous hydrogen chloride is added to the gas before washing.
