CISDI Engineering Technology Co., Ltd., Chongqing 401122, China) 【 】The anticorrosion technologies for blast furnace gas after dry dust removal Abstract operation are summarized and the new full-dry acid removal technology based on dry absorp- tion tower is introduced, of which the feasibility for industrial application is discussed. CISDI’ s new-type dry acid removal technology based on dry absorber can perfectly solve the prob- lem of corrosion and salification in all kinds of equipment and user pipe networks including TRT. When chlorine content in gas is less then 60 mg/m, the overall effect of energy saving3 and efficiency improvement of the method is significantly better than that of wet acid removal method, provinggood applicationvalue. 【 】Blastfurnacegas; drydustremoval;dryacid removal
