Cloud aluminum flue gas desulfurization comprehensive utilization technology has reached the international advanced level

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. Yunnan Aluminum Co., Ltd. has developed the complete process flue gas desulphurization technology and equipment for the aluminum industry for the typical characteristics of current aluminum industrial alumina production furnaces (kilns), petroleum coke calciners (kilns) and aluminum electrolysis flue gas, and built China. The first full-process flue gas sulfur dioxide treatment industrialization application demonstration system reached the international advanced level. The comprehensive desulfurization efficiency can reach more than 75% and sulfur dioxide emissions ≤ 50mg/m3, which is much lower than the "Aluminum Industry Pollutants Emission Standard", and provides a demonstration for the global green aluminum industry.
