According to the bulk non-ferrous net reprint: the aluminum production process contains different levels of sulfur dioxide, reducing and controlling the emission of sulfur dioxide in the aluminum industry, the task is very urgent.
A few days ago, Yunnan Aluminum Co., Ltd. developed the complete process flue gas desulphurization technology and equipment for the aluminum industry in response to the typical characteristics of the current aluminum industry alumina production furnace (kiln), petroleum coke calciner (kiln) and aluminum electrolysis flue gas. Completed the first industrialized application demonstration system for China's first full-process flue gas sulfur dioxide treatment. The technical indicators have reached the international advanced level. The comprehensive desulfurization efficiency of the system can reach more than 75%, sulfur dioxide emissions ≤ 50mg/m3, much lower than the "aluminum industry pollutant discharge standards," and provides a demonstration for the global aluminum industry's comprehensive utilization of aluminum flue gas desulfurization.
