ABSTRACT

This paper provides an in-depth analysis of the various flue gas desulfurization technologies employed in the context of China's rapidly growing energy sector. With the nation's industrial expansion leading to unprecedented levels of sulfur dioxide (SO2) emissions, the need for efficient and effective desulfurization methods is paramount. This study systematically examines multiple desulfurization techniques, including limestone-gypsum, ammonia alkali, dual alkali, magnesium oxide, organic amine methods. The research evaluates each method based on its operational mechanics, efficiency, economic feasibility, environmental impact, and suitability for China's specific industrial conditions. Limestone-gypsum desulfurization, while prevalent, is contrasted with emerging alternatives that offer potential advantages in terms of efficiency, cost, and environmental sustainability. Special attention is given to innovative approaches such as magnesium oxide and organic amine methods, which demonstrate high efficiency and lower ecological footprints. The findings of this study indicate a trend towards more sustainable and cost-effective desulfurization techniques, highlighting the need for continued research and development in this field.
