Abstract	Reaction network model is key to ethylene cracking process simulation. Studying an ethylene cracking reaction (ECR) network involving hundreds of components and thousands of reactions is challenging. To facilitate a rapid and comprehensive reaction network analysis and improve ECR network, authors present a ranking algorithm called network flow analysis algorithm (NFAA) to a reaction network analysis procedure. NFAA analyzes the reaction network with comprehensive information, including network topological structure, reaction mechanism, and process model data. Following NFAA, reactions and species are ranked based on their significances. According to the ranking of reactions, unimportant reactions (lower ranking) in ECR network are removed to reduce ECR network complexity and decrease computational scale without loss of prediction accuracy.
