| Abstract: |
| Under the background of "dual carbon", the electrolytic aluminum industry is facing great pressure to reduce emissions. Based on the investigation of the carbon emission status of each link of electrolytic aluminum production in China, the carbon emission level of each link was compared, and the current research status, main measures and carbon reduction effects of each link were reviewed, the gaps were found and the reasons were analyzed, and measures for carbon emission reduction of electrolytic aluminum in Yunnan Province were proposed and the emission reduction potential was calculated. The results show that the proportion of carbon emissions of electrolytic aluminum industry in Yunnan Province is higher than the national average level, and the total carbon emissions of electrolytic aluminum industry will be reduced by more than 30% in 2025 after improving the green electricity structure, which is much higher than the national target of 5.82% carbon emission reduction of electrolytic aluminum power structure. Anode carbon consumption carbon emissions account for the largest proportion of carbon emissions in addition to electricity carbon emissions, through the use of high-quality anode can reduce carbon emissions by 1.20%. After the innovation of advanced technology, the comprehensive AC power consumption of liquid aluminum can reach the level of advanced clean production, and the carbon emission can be reduced by 0.63%. The anode-effect perfluorocarbon emissions of electrolytic aluminum production in China are much higher than those of other developed countries, and the anode-effect carbon emissions of electrolytic aluminum industry in Yunnan province will be reduced by 1.31% in the next five years. |
