【摘要】 以云南省为例，核算工业硅污染物排放及生产各环节碳排放水平，提出云南省工业硅在污染物及碳排放减排的主要途径和潜力。分析认为，提高设备的大型化水平，推进烟气负压改造、配套脱硫措施和脱硝技术工业化应用，可减少氮氧化物和二氧化硫8.244万t/a和0.916万t/a。提高绿色用电比例、降低电耗和替代还原剂是工业硅降低碳排放三个主要途径，基于目前规划和技术研究现状，到2025年三个主要途径碳减排潜力分别为2.23%、3.70%和14.02%，总体碳减排潜力为19.95%。更多还原

【Abstract】 Taking Yunnan Province as a case study, accounting for pollutant emissions and carbon emission level across industrial silicon production processes, and proposing key pathways and potential for pollution and carbon reduction in Yunnan’s industrial silicon sector. The analysis suggests that enhancing equipment scale-up, implementing flue gas negative pressure retrofitting,and adopting desulfurization measures alongside industrialized denitrification technologies could reduce nitrogen oxide emissions by82,440 t/a and sulfur dioxide emissions by 9,160 t/a. Increasing the proportion of green electricity, reducing power consumption, and substituting reducing agents are the three primary pathways for carbon emission reduction in industrial silicon production. Based on current planning and technological research, these pathways are projected to achieve carbon reduction potentials of 2.23%, 3.70%, and14.02% respectively by 2025, yielding an overall carbon reduction potential of 19.95%.更多还原
