EXAMINATION OF EFFECTS ON HOMOGENEOUS OXIDATION OF MERCURY BY HCl
IntroductionAnthropogenic emissions of mercury have brought a global environmental problem. Mercury emissions from coal-fire power plants represented a significant fraction of the anthropogenic emissions of mercury into the atmosphere. In 1997, U.S. EPA had estimated that during the years of 1994-1995, 158t mercury was being released annually into the environment, of which amount, 48t was derived from coal-fired utilities.1-2 Mercury in the flue gas was most commonly classified in three forms: elemental mercury (HgO), oxidized mercury (Hg2+), and particle bound mercury (HgP).3 Elemental mercury was unsolvable in water, with high volatility, and difficult to capture since its nonreactivity. Conversely, oxidized mercury could be easily dissolved in water, and had an affinity for adsorbing onto the surface of fly ash, which made it easily to be removed from flue gas by APCDs in coal-fire power plant. Therefore, the quantities of mercury emissions from coal-fire power plants were strongly affected by the form of mercury emitted from point sources, which was associated with the type of the coal, flue gas components and temperature, characteristic of fly ash, APCDs in the plants.
