Scenario analysis on abating industrial process greenhouse gas emissions from adipic acid production in China

Adipic acid is an important petrochemical product, and its production process emits a high concentration of greenhouse gas N 2 O. This paper aims to provide quantitative references for relevant authorities to formulate greenhouse gas control roadmaps. The forecasting method of this paper is consistent with the published national inventory in terms of caliber. Based on the N 2 O abatement technical parameters of adipic acid and the production trend, this paper combines the scenario analysis and provides a measurement of comprehensive N 2 O abatement effect of the entire industry in China. Four future scenarios are assumed. The baseline scenario (BAUS) is a frozen scenario. Three emission abatement scenarios (ANAS, SNAS, and ENAS) are assumed under different strength of abatement driving parameters. The results show that China’s adipic acid production process can achieve increasingly significant N 2 O emission abatement effects. Compared to the baseline scenario, by 2030, the N 2 O emission abatements of the three emission abatement scenarios can reach 207–399 kt and the emission abatement ratios can reach 32.5%–62.6%. By 2050, the N 2 O emission abatements for the three emission abatement scenarios can reach 387–540 kt and the emission abatement ratios can reach 71.4%–99.6%.
