The BLEVE Research of Reaction Runaway Based on the Aspen Plus-Fluent

A new scene analysis method of reactor thermal explosion accident based on process simulation and CFD method is proposed. The thermal runaway of batch reactor with methanol and acetic anhydride is simulated by Aspen Plus. The molecular weight and component concentration of steam after explosion overpressure are studied. The vapor cloud explosion is simulated by Fluent. The propagation law of vapor cloud explosion pressure wave and flame front is analyzed based on the simulation results.
