Application and Modification of Desulfurization Process of Hydrogen Peroxide from Acid Tail Gas by Wet Zinc Smelting
In response to the shortcomings of the zinc oxide tail gas desulfurization process used in a wet zinc smelting plant,the advantages and disadvantages of limestone-gypsum,caustic soda,ionic liquid,and hydrogen peroxide desulfurization processes were compared.The Hydrogen peroxide methodwas selected,which has a short process,high desulfurization efficiency,and no secondary pollutants.This process was implemented for transformation,achieving stable and efficient production,ultra-low tail gas emissions,and desulfurization by-product resource utilization.The environmental and economic benefits are obvious.
