Method for removing mercury from gas

Dec 07, 2001The use of a selenium filter is described for example in U.S. Pat. No. 3,786,619, where the method is based on the reaction between gaseous mercury and solid selenium. An inert porous filter material is used in this method, onto which a solution containing selenium dioxide, SeO 2, is absorbed and dried. Selenium dioxide is reduced by the effect

Hg Removal

The filter is then treated to recover the mercury and regenerate the selenium. The filter will remove approximately 90% of the incoming mercury. Selenium Scrubber The technology developed by Boliden Norzink was purchased by Outokumpu in 200x and is now part of Outotec which was spun off from Outokumpu Technology. Carbon Filter.

Method of recycling an exhausted selenium filter mass

The invention claimed is: 1. A process for reclaiming spent selenium filter mass comprised of an inert material, residual selenium active substance and mercury selenide, said process comprising: treating the spent selenium filter mass with a hydrogen peroxide solution for leaching out the selenium content in essentially all of the residual selenium active substance so as to form selenious acid

Dec 13, 2003The filter mass is treated with aqua regia solution to dissolve mercury selenide present in the mass. The aqua regia solution is separated from the mass and isolated. Suitably, the filter mass, which now contains inert carrier material, is transferred with the isolated selenious acid, to production of new selenium filter mass.
