Process Improvement of Dry Method Fine Desulfurization of Blast Furnace Gas
This paper introduces the mainstream dry method for fine desulfurization of blast furnace gas,and points out that insufficient chlorine removal and water and dust in the furnace gas are key problems restricting further development of fine desulfurization of the blast furnace gas.By combining engineering application,a fine desulfurization process of"two-stage pretreatment+hydrolysis catalysis+dry desulfurization"is proposed,and the grading scheme is given according to characteristics of doses at different stages,which provides reliable technical support for blast furnace gas fine desulfurization projects under different working conditions.
