Dry dedusting technology for blast furnace gas offers significant advantages such as saving water, fully utilizing sensible heat and generating more electricity, and has become a preferred gas purification process. However, the technlogy is restained due to the acidic corrosion problems by blast furnace gas with dry dedusting process. Adhering the advantages of dry dedusting technology, it is imperative to find a solution to remove the acidic corrosion compoents..In this project, dry synergistic removal of acidic corrosion components from blast furnace gas will be investigated. Based on the typical characteristics of the temperature, and components of blast furnace gas and the reactivity of different acidic components, we will study the thermodynamics and kinetics of the dry removal reactions for the acidic components. Then we will clarify the correlationship among blast furnace gas, acidic components and the component and microstructure of the deacidic agents. In the project, clarifying the removal reaction mechanism of the acidic components would be a solution to solve the corrosion problems and provide fundamental theory and technical support for exploring and development of the dry dedusting process.
