ABSTRACT:
Process for removing mercury from a gas contaminated with mercury vapor, comprising the steps of cooling the contaminated gas, removing water vapor from the cooled gas and filtering the dehydrated gas through a medium comprised of pure elemental sulfur. The mercury bound to the medium may be removed by heating liquid carbon disulfide to form a carbon disulfide vapor, cooling the carbon disulfide vapor so that liquid carbon disulfide is formed, spraying the liquid carbon disulfide over the medium containing the bound mercury, so as to remove the mercury from the medium and allowing elemental sulfur to dissolve into the liquid carbon disulfide and allowing said elemental mercury to separate away from the elemental sulfur/carbon disulfide solution.
