Research progress on synergistic control of air pollutants and CO2 in electrolytic aluminum industry
Synergistic control of air pollutants and CO2 is an important path for the electrolytic aluminum industry to solve the air pollution problems and achieve large reduction of CO2.Characteristics of air pollutants and CO2 emis-sions from the electrolytic aluminum industry,as well as flue gas purification technology and carbon capture technol-ogy are introduced.Focusing on the synergistic control measures of air pollutants and CO2 in the electrolytic alumi-num industry in recent years,the research progress of inert anodes,low-temperature aluminum electrolysis,waste heat recovery are reviewed.The role of renewable energy in supporting the synergy of pollution reduction and carbon reduction in electrolytic aluminum enterprises is analyzed.At present,air pollutants and CO2 emitted by the alumi-num electrolysis industry come from the same source and have the same process characteristics.However,the cur-rent flue gas purification technology and CO2 emission reduction is showing negative synergy characteristics.In or-der to achieve synergies between pollution reduction and carbon reduction,it is necessary to carry out in-depth re-search and industrial tests on technologies related to source control and process optimization.It is also necessary to promote the integration of renewable energy and the electrolytic aluminum industry,and explore the carbon emission reduction value transformation path of renewable energy power in the aluminum industry,to provide strong support for the deepening of green and low-carbon development of aluminum industry under the background of"Carbon Peak""Carbon Neutrality".
