Experimental evaluation of sorbents for the capture of mercury in flue gases
The results and conclusions to date from the Argonne research program on air toxics (mercury) control can be summarized as follows: (1) Mercury emissions from coal-fired combustors are generally in the range of 10--70 {mu}g/m{sup 3} and are highly variable. (2) Existing FGC technologies are only partially effective in controlling mercury emissions. (3) Lime hydrates, either regular or high-surface-area, are not effective in removing mercury. (4) Mercury removals are enhanced by the addition of activated carbon. (5) Mercury removals with activated carbon decrease with increasing temperature, larger particle size, and decreasing mercury concentration in the gas. (6) Chemical pretreatment (with sulfur or CaCl{sub 2}) can greatly increase the removal capacity of activated carbon.
