摘要:

黄磷作为高耗能、高碳排放产品,摸清其碳排放足迹,促进其低碳发展对中国“双碳”战略具有重要意义。以贵州省某5万t/a黄磷企业为例,采用生命周期评价法(Life Cycle Assessment,LCA),定量分析黄磷产品在其生产过程中的碳足迹(Carbon Footprint),并为其绿色低碳发展提出相应的节能降碳建议措施。研究结果表明:在黄磷生产过程中,每吨黄磷在其生命周期内碳足迹为1.580×104 kg CO2;其碳排放主要集中在尾气处理和电力消耗两个方面,二者占总量的90.08%;依据其碳足迹核算结果提出采用绿色电力生产、合理利用磷矿资源地理位置优势、加强工艺控制、黄磷尾气综合利用等减排措施,以此达到减少黄磷产品生产过程碳足迹的目的。

Abstract:

Yellow phosphorus,as a high energy consumption and high carbon emission product,to find out its carbon emission footprint and promote its low carbon development is of great significance to our “double carbon” strategy.Taking a 50 000 t/a yellow phosphorus enterprise in Guizhou province as an example,Life Cycle Assessment(LCA) was adopted to quantitatively analyze the carbon footprint of yellow phosphorus products in the production process,and proposed corresponding energy-saving and carbon reduction measures for its green and low-carbon development.The research results showed that the carbon footprint of each ton of yellow phosphorus in the production process was 1.580×104 kg CO2.The carbon emissions were concentrated in the two aspects of tail gas treatment and power consumption,which was accounted for 90.08% of the total.Based on its carbon footprint accounting results,it was proposed to adopt green power production,rational use of the geographical advantages of phosphorus resources,strengthen process control,and comprehensive utilization of yellow phosphorus tail gas and other emission reduction measures to reduce the carbon footprint of yellow phosphorus production process.

Key words: “dual carbon” strategy, life cycle assessment, yellow phosphorus, carbon footprint, energy conservation and carbon reduction
