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
