Environmental impact assessment of China’s primary aluminum based on life cycle assessment. Trans Nonferrous Met Soc China 29, 1784–1792 (2019). This dataset should be used to model the environmental impacts of producing alumina for the primary aluminum production process. Users should ensure the exclusion of the impacts of bauxite mining from this data set as it focuses solely on the sintering process. The dataset might require updates with new technology changes in sintering processes or alterations in regulatory standards. The date of publication should be considered to guarantee methodological consistency and data relevance. 该数据集应用于模拟原铝生产工艺中生产氧化铝的环境影响。用户应确保从该数据集中排除铝土矿开采的影响，因为它仅关注烧结过程。随着烧结工艺的新技术变化或法规标准的修改，可能需要对数据集进行更新。应考虑文献发表日期以保证方法论的一致性和数据的相关性。此外，该过程仅有能源数据，仅作为能源消耗的参考数据，如需使用请根据实际情况补全其它信息。 Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044. 清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。 Tiangong LCI Data Working Group 天工LCI数据工作小组 Chenling Fu, fu-chenling@tsinghua.edu.cn 傅晨玲, fu-chenling@tsinghua.edu.cn fu-chenling@tsinghua.edu.cn fu-chenling@tsinghua.edu.cn 2024-01-10T09:04:38+08:00 2024-04-20T15:31:00.044867+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=4dd706d4-9c3d-4bbf-9f87-cea5aeb5c88d&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 false Free of charge for all users and uses electricity, high voltage, aluminium industry Input 1389.6000000000001 1389.6000000000001 soda ash, dense Input 87.3 87.3 limestone, crushed, for mill Input 806.0 806.0 limestone carbon dioxide (fossil),carbon dioxide (fossil) Output 1.79 1.79 particles, unspecified Output 8.14 8.14 bauxite Input 1920.0 1920.0 Water, unspecified natural origin Input 4370.0 4370.0 hard coal Input 850.0 850.0 steam, in chemical industry Input 2920.0 2920.0 aluminium oxide, metallurgical Output 1000.0 1000.0 redmud from bauxite digestion Output 1430.0 1430.0 sulfur dioxide Output 0.00147 0.00147 sulfur dioxide Output 0.00266 0.00266 Nitrogen oxides Output 0.00636 0.00636 methane (fossil) Output 0.00017999999999999998 0.00017999999999999998
