全混流反应器异常操作工况下反应温度预测方法及危害分析OA北大核心CSTPCD

The kinetic parameters of the primary reaction in the tank reactor were obtained by the mathematical fitting method according to the experimental data of reactant concentration changes at different temperatures,and those of the secondary reaction were determined according to the relationship between the temperature of the secondary reaction and time by accelerating rate calorimeter.The temperature prediction model of a continuous stirred tank reactor(CSTR)was established based on the calorimetry and reaction kinetics.The prediction method of reaction temperature of CSTR under abnormal operating conditions was studied,and the hazard analysis was carried out.The simulation results show that for a conventional n-order exothermic reaction,the model can easily and accurately simulate the relationship between operating parameters and time in the CSTR under different operating conditions,and the reaction temperature can reach the highest value of 130℃under heat transfer failure conditions.The established model can quantitatively simulate the changes in reaction temperature,component concentration,and heat load under abnormal operating conditions,and it can provide data support for reaction hazard analysis of the CSTR under abnormal operating conditions,which has guiding significance for the design of reaction process and reactor and the realization of intrinsic safety.
