摘要
全球气候变化已成为21世纪人类共同面对的挑战,建立统一的碳排放交易市场、减少工业生产的碳排放已经成为全球共识。皮江法炼镁因存在高能耗、高碳排放量等问题饱受诟病。采用生命周期评价方法,运用自主生命周期软件定量评价了我国2011年皮江法、2020年皮江法和电解法生产金属镁过程中的碳足迹,以期为国内镁行业的碳减排提供指导以及有效应对碳排放交易市场建立带来的挑战。研究表明,我国皮江法生产镁在2020年的资源能源利用效率显著提高,碳排放为2.5×10^(4) kg CO_(2)-eq较2011年皮江法生产镁的碳排放3.12×10^(4) kg CO_(2)-eq相比明显降低并与电解法生产镁的碳排放2.38×10^(4) kg CO_(2)-eq基本持平。进一步研发新技术、使用清洁能源和完善碳交易平台将推动中国的原镁产业持续健康发展。
Global climate change has become a common challenge to mankind in the 21 st century.It has become a global consensus to establish a unified carbon emission trading market and reduce the carbon emission from industrial production.Magnesium produced by Pidgeon method has been criticized for its high energy consumption and carbon emission.In this paper,the life cycle assessment method and the independent life cycle software were used to quantitatively evaluate the carbon footprint in the process of producing magnesium by Pidgeon method in 2011,Pidgeon method in 2020 and the electrolysis method in China,so as to provide guidance for the carbon emission reduction of the domestic magnesium industry and effectively deal with the challenges brought by the establishment of the carbon emission trading market.The results showed that the resource and energy utilization efficiency of magnesium produced by the Pidgeon method in China were significantly improved in 2020,and the carbon emission of 2.5×10^(4) kg CO_(2)-eq produced by the Pidgeon method in 2020 was significantly reduced compared with the carbon emission of 3.12×10^(4) kg CO_(2)-eq produced by the Pidgeon method in 2011,which was basically equal to the carbon emission of 2.38×10^(4) kg CO_(2)-eq produced by the electrolysis method.The further research and development of new technologies,the use of clean energy and the improvement of carbon trading platform will promote the sustainable and healthy development of Chinese original magnesium industry.
