| Abstract: |
| As an important raw material industry, the production process of alumina industry is mainly divided into Bayer process, sintering process and Bayer-sintering combined process. The process flow is complex and the industrial scale is big, resulting in a large amount of carbon dioxide emissions. The current situation of carbon emission accounting in alumina industry was analyzed. According to the specific material balance calculation in the process of production, with the material balance accounting method as the main method and the emission factor accounting method as the auxiliary method, the carbon emission accounting for the Bayer process alumina production process, the sintering process alumina production process and the three combined process alumina production processes, parallel, series and mixed, were carried out, and the relevant accounting formulas were clarified, and the relevant data was selected for actual accounting. |
