Abstract

The important step for increasing gaseous elemental mercury (Hg0) removal in wet scrubber systems is altering the chemical form of the Hg0to a water-soluble oxidized species. This work focuses on the removal of elemental mercury from simulated flue gas by aqueous K2S2O8in a bubble reactor. In the system of K2S2O8oxidize Hg0, the reaction velocity of K2S2O8and Hg0is soon. Reached a higher removal rate after 10min. Increase the concentration of K2S2O8can remarkably improve the removal rate of Hg0to 85% With the rise of import mercury concentration has increased mercury removal rate to 89.5%.
