Oxidation removal of elemental mercury from flue gas by K2S2O8
Applied Mechanics and Materials(2012)
摘要
The important step for increasing gaseous elemental mercury (H-g(0)) removal in wet scrubber systems is altering the chemical form of the H-g(0) to a water-soluble oxidized species. This work focuses on the removal of elemental mercury from simulated flue gas by aqueous K2S2O8 in a bubble reactor. In the system of K2S2O8 oxidize H-g(0), the reaction velocity of K2S2O8 and H-g(0) is soon. Reached a higher removal rate after 10min. Increase the concentration of K2S2O8 can remarkably improve the removal rate of H-g(0) to 85% With the rise of import mercury concentration has increased mercury removal rate to 89.5%.
