Results and discussion The P-graph optimization selected the ethylene route as the most economically and environmentally balanced pathway for acrylic acid production, yielding an annual profit of USD 25.9 M (Figure 2). Conclusions This study demonstrated the benefit of the P-graph methodology for facilitating systematic decision-making in pathway selection and optimization in acrylic acid production.	cache/cet-15672.pdf	txt/cet-15672.txt
