Abstract:Thermal runaway incidents often imply explosions and casualties, especially for the nitration process. However, limited by coupling relations among units, it is challenging to analyze thermal safety in a complex process. In this study, a novel solution strategy is proposed to analyze the safe steady-state operating space for a complex nitration process with seven reactors in a countercurrent connection. The thermal risk issue is assessed in detail by mechanism-based modeling and simulation. A multilevel optimi… Show more
