20090004085 | Method and System for Removing Mercury from Flue Gas - A biomass feeding unit feeds biomass to a boiler. A hydrogen-chlorine monitoring unit measures hydrogen-chloride content in flue gas fed to a desulfurization equipment. A mercury monitoring unit measures mercury content in treated flue gas emitted from the desulfurization equipment. A feed-amount instruction unit instructs proper feed amount of the biomass to the biomass feeding unit based on measurement values obtained by the hydrogen-chlorine monitoring unit and the mercury monitoring unit. | 01-01-2009 |
20090188393 | FLUE GAS DESULFURIZATION APPARATUS - A flue gas desulfurization apparatus includes an absorption tower that absorbs sulfur oxide in a flue gas, and drift suppression members that are arranged near a bend portion of a purified gas exhaust passage arranged at an outlet portion of the absorption tower, the drift suppression members serving to collect mist particles. | 07-30-2009 |
20090269241 | Method for removing mercury in exhaust gas and system therefor - The present invention provides a method for removing mercury in exhaust gas, in which mercury in exhaust gas discharged from combustion equipment is removed, characterized by including a mercury oxidation process in which mercury in the exhaust gas is converted to mercury chloride in the presence of a catalyst; a contact process in which the exhaust gas is brought into contact with an absorbing solution in a scrubber to absorb and remove mercury components from the exhaust gas; and a control process in which blowing of air or addition of an oxidizing agent into the scrubber is accomplished, and the amount of blown air or the added amount of oxidizing agent is regulated to control the oxidation-reduction potential of the absorbing agent, and a system for removing mercury in exhaust gas. According to the mercury removing method in accordance with the present invention, a phenomenon that mercury chloride is reduced into metallic mercury by SO | 10-29-2009 |
