| Abstract: |
| In order to serve the national strategy of carbon reduction, a typical soybean oil processing enterprise was taken as the research object, the calculation boundary of carbon emission was clarified, changes in energy consumption indicators were sorted out, and the carbon emission coefficient method was used to determine the carbon dioxide emission of the enterprise. The carbon dioxide emission of soybean oil processing industry in China from 2015 to 2022 were calculated, and carbon reduction measures were proposed. The results showed that before 2020, the carbon dioxide emission of the enterprise was 0.111 t/t (based on soybean), and after 2020, after process improvement, the carbon dioxide emission was 0.097 t/t (based on soybean). The carbon dioxide emission of the soybean oil processing industry reached its peak in 2017, reaching 10.95 million tons. If the processing energy consumption steadily decreases, although the soybean consumption will reach its maximum value (126 million tons) in 2030, the carbon dioxide emission of the soybean oil processing industry was still at its peak in 2017. Steam and electricity consumption are the main factors influencing the carbon emission of oil processing industry. To promote the achievement of carbon reduction targets, the main carbon reduction path of soybean oil processing industry is to reduce steam and electricity consumption through continuous management and process improvement. |
