摘要
降低金属冶炼工业过程中的能耗和碳排放量是当前一项紧迫而重要的任务。本研究对铜冶炼的能效和碳效率评价方法进行了研究和分析，并探索对应的效率提升方法。在这项工作中，基于松弛变量数据包络分析方法（SBM-DEA）和超效率SBM-DEA模型评估过去三年中某典型铜冶炼企业不同月份的铜冶炼相对能源效率，并定量分析了最佳能效和较低能效月份对应的铜冶炼过程能流与碳排放流分布特性。在最佳能效月，三个不同计算边界范围内精炼铜生产的能耗分别为5044、8446和10037MJ/t⋅Cu；三个不同计算边界内的铜冶炼碳效率分别为1.804、1.027和0.855 kg⋅Cu/kg⋅CO2。并对冶炼能效的影响因素进行了分析，根据分析结果提出了提高冶炼能效、碳效的建议或措施。该研究将为铜冶金行业的能效评估与提升、减少碳排放量提供可用的方法和理论参考，也将为能源密集型的冶金行业的碳中和进程做出贡献。
Abstract
Reducing energy consumption and carbon emissions in the metal smelting industry is an urgent and essential task at present. This study investigated and analyzed the energy efficiency and carbon efficiency evaluation methods for copper smelting, and explored corresponding efficiency improvement methods. The relative energy efficiency of copper smelting in different months of a typical copper smelting enterprise over the past three years was evaluated based on the slack variable data envelopment analysis method (SBM-DEA) and the super efficiency SBM-DEA model. The distribution characteristics of energy flow and carbon emissions during the copper smelting process corresponding to the best energy efficiency and lower energy efficiency months were quantitatively analyzed. In the optimal energy efficiency month, the energy consumption for refined copper production within three different calculation boundary ranges is 5044, 8446, and 10037 MJ/t⋅Cu, respectively; The carbon efficiencies of copper smelting within three different calculation boundaries are 1.804, 1.027, and 0.855 kg⋅Cu/kg⋅CO2, respectively. The influencing factors of smelting energy efficiency, and proposed suggestions or measures to improve smelting energy efficiency and carbon efficiency based on the analysis results are investigated. This study will provide practical methods and theoretical references for energy efficiency assessment and improvement, as well as reducing carbon emissions in the copper metallurgical industry. It will also contribute to the carbon neutrality process in the energy-intensive metallurgical industry.
