摘要： PROBLEM TO BE SOLVED: To separate and remove zero-valent mercury gas from treating object gas at a sufficient removal rate while suppressing an amount of use of a mercury oxidizing agent. SOLUTION: The apparatus converts zero-valent mercury gas into water-soluble bivalent mercury gas to separate and remove the zero-valent mercury gas from the treating object gas, and has a reaction separation means 4A bringing an aqueous solution containing the mercury oxidizing agent containing trivalent iron (Fe 3+ ) as a component, and having pH of 3 or less into contact with the treating object gas.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas treating method and a treatment apparatus with which mercury can be highly efficiently removed regardless of the kinds of coal or properties of exhaust gas discharged from a combustion apparatus when burning coal in the combustion apparatus like a boiler, and a further reduced cost can be achieved. SOLUTION: The exhaust gas treating method for removing the mercury contained in exhaust gas discharged from a coal-burning boiler B when burning fossil fuel like coal in the coal-burning boiler B, includes an additive feed part 15 feeding the chlorine-containing additive to any place from a coal storage yard 10 to the coal-burning boiler B in order to heighten concentration of hydrogen chloride contained in exhaust gas discharged from the coal-burning boiler B, and the chlorine-containing additive is chlorine-containing waste as it is, or a product formed by processing it.

摘要： PROBLEM TO BE SOLVED: To remove mercury from treating object gas and to suppress the occurrence of corrosion due to a mercury removing agent. SOLUTION: This mercury removal apparatus separates insoluble mercury by converting it to water-soluble mercury and removes the water-soluble mercury from the treating object gas in a treatment chamber 4B1. The apparatus is provided with reaction separation means 4B1, 4B2, 43 bringing treating object liquid W2 containing a mercury oxidizing agent having a substance as a component with a redox potential equal to or below that which causes corrosion of inner walls or inner structure of the treatment chamber 4B1, into contact with the treating object gas.
