数据集使用建议 使用直接还原铁(DRI)路线的LCI数据时,必须参考中国相关示范项目的平均操作数据。方法学建议包括确保建模反映了为COG-DR和H-DR路线概述的特定技术应用和能量输入,并考虑中国语境下的可扩展性。数据应注意到它包括了来自模拟、实验室测试和过程建模的估计,并且可能需要调整,以便应用于所研究之外的情境或技术设置。此外,在考虑将LCI数据纳入全面的环境评估时,确保正确定义系统边界,特别是关于随后的循环利用过程的包含或排除。
产品或过程的技术目的 所描述的过程涉及使用基于煤的直接还原工艺生产直接还原铁(DRI)。这种DRI生产通常是钢铁制造工业的一部分,在这里它作为传统高炉方法的更清洁的替代铁源。该过程利用焦炉产生的副产品气(焦炉煤气,COG)进行直接还原铁(DRI)生成过程。它适用于寻求减少对焦煤依赖、提高能源效率和降低温室气体排放的工业钢铁生产设施。
