METHOD AND APPARATUS FOR PROCESSING EXHAUST GAS |
摘要 |
<p>Disclosed are a method and an apparatus for processing an exhaust gas, which enable to suppress decrease of pH and increase of ORP of a mixture of an aqueous solution of a reducing agent and an aqueous alkali solution circulated within a wet reactor comprising a reduction reaction region and an oxidation reaction region. The method and apparatus enable to prevent deterioration of the mixed aqueous solution, and can be continuously operated for a long time. Specifically, the ORP and pH of the mixed aqueous solution of the aqueous solution of a reducing agent and the aqueous alkali solution to be circulated within the wet reactor are measured, and a fresh aqueous solution of a reducing agent and a fresh aqueous alkali solution are supplied, if necessary, into a reservoir unit arranged in the lower part of the wet reactor so that the ORP and pH of the mixed aqueous solution are kept within predetermined ranges.</p> |
