| Abstract: |
| As an energy based industry, aluminum electrolysis industry emits carbon dioxide in the production process, and a large amount of thermal power consumption also leads to a large amount of carbon dioxide emissions, but there are still many unclear aspects in its carbon emissions accounting boundary, accounting methods, etc. The current situation of carbon emission accounting in aluminum electrolysis industry was analyzed. The accounting principle of separately accounting and summing up according to carbon emissions in different production processes of aluminum electrolysis were established. The carbon emissions in baking startup process, carbon emissions in pre baked anode consumption and indirect carbon emissions in energy consumption in the normal electrolysis process, carbon emissions in anode effect process and total carbon emissions in aluminum electrolysis were listed respectively. The relevant data was select to carry on the actual calculation. |
