Abstract:The operation status of activated coke and organic amine desulfurization processes in the sulfuric acid workshop of Guixi Smelter is introduced. The problems and solutions of the two practical desulfurization processes of active coke and organic amine are analyzed. Making a comparison from the aspects of process characteristics, operating effects, investment and operating costs,the advantages and disadvantages of these two desulfurization processes are summarized, which can provide reference for process optimization and technical improvement in the same industry.
