Adsorpiton experiments of mercury compounds by sulfur-impregnated activated carbons
have been performed using by-passed flue gas from a real waste incinerator. Using
commercial grade sulfur-impregnated activated carbons, the removal efficiency of mercury
compound was 97% at temperature of 80 ℃. The sulfur-impregnated activated carbon also
showed the similar level at high temperature, 140 ℃, mainly due to the chemical
adsorption (chemi-sorption) effect increasing with temperature increase. With the initail
mercury concentration higher than 200 ㎍/Nm3, the mercury concentrations after two stages
was lower than 10 ㎍/Nm3, which is low enough compared to the German regulation limit
on mercury in the incineration flue gas, 30 ㎍/Nm3. The cumulative removal efficiency of
the two stages(the first and the second) was 95%. However, the mercury concentration
cannot be lower than 10 ㎍/Nm3 in this fixed-bed adsorption facility, and the overall
mercury removal efficiency was limited. The pressure drop at this fixed adsorption bed was
between 46 and 82 mmH2O for the serial flow configuration, and became as small as 26
mmH2O for the parallel flow configuration.
