氧化铝工业碳排放核算方法

氧化铝工业作为重要的原材料产业，其生产工艺主要为拜耳法、烧结法及拜耳—烧结联合法，工艺流程复杂，产业规模巨大，造成大量二氧化碳排放。分析了氧化铝工业碳排放核算现状，根据工艺生产过程中的具体物料衡算，以物料平衡核算法为主、排放因子核算法为辅，分别对拜耳法氧化铝生产工艺、烧结法氧化铝生产工艺，以及并联、串联、混联三种联合法氧化铝生产工艺进行了碳排放核算，明确了相关核算公式，并选取相关数据进行了实际核算。

Carbon Emission Accounting Methods of Alumina Industry

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.
