Core Viewpoint - The "Precision Denitrification Technology for Magnesium Smelting Industry" has been launched in Fugu County, marking a global innovation that addresses nitrogen oxide emissions in China's magnesium smelting sector [1][2]. Group 1: Industry Context - Shaanxi Province is the largest producer of metallic magnesium globally, maintaining the top position for over a decade, but faces significant challenges related to high nitrogen oxide emissions and environmental pressures during the smelting process [1]. - The technology was developed in response to the clean production needs of the magnesium smelting industry, particularly in northern Shaanxi [1]. Group 2: Technological Innovation - The new denitrification technology is a world-first specifically designed for the magnesium smelting industry, capable of reducing nitrogen oxide emissions by approximately 10,000 tons annually, which represents a 70% reduction in emission levels [1]. - The technology integrates a "dual-section" denitrification solution that eliminates reliance on traditional SCR denitrification methods, with costs controlled between 80 to 90 yuan per ton of magnesium [2]. Group 3: Environmental and Economic Impact - The implementation of this technology is equivalent to creating 20 square kilometers of forest in terms of environmental benefits [1]. - The technology also allows for the recycling of ammonia-containing wastewater, saving approximately 180 million yuan annually in disposal costs, thus promoting a green circular economy in the magnesium smelting industry [2]. - The technology has been successfully applied at Yufeng Magnesium Alloy Co., Ltd., achieving stable operation for over four months with emissions meeting regulatory standards [2].
