摘　　要：反应热失控是引起设备超压的重要原因,而安全可靠的安全泄放系统设计是防止设备发生超压破坏的最有效方法。本文采用ChemCAD中的DIERS紧急泄放模块对硝基胍硝化过程的紧急泄放系统进行了设计与计算。根据硝基胍硝化过程热失控的特点,计算出反应器在热失控条件下的最小紧急泄放面积为0.00084 m^(2),在此泄放面积下,才可保证泄放压力低于反应器的设计压力。并给出了紧急泄放情况下硝基胍硝化反应器内的温度和压力变化曲线,同时通过不同泄放面积下反应器的温度和压力变化情况对紧急泄放系统进行了评估。Exothermic reaction runaway was the main cause of fluid equipment overpressure,and the reliable relief device design was the most effective method to avoid overpressure.By using the DIERS module of ChemCAD,the relief system of Nitroguanidine Nitration Reaction was designed.Based on the characteristics of nitration reaction thermal runaway,the minimum reactor emergency discharge area was calculated as 0.00084 m^(2)to ensure the discharge pressure lower than the reactor design pressure of 0.6 MPa.The curves of temperature and pressure in the nitration reactor under emergency discharge was also calculated,meanwhile,the designed emergency discharge system was evaluated according to simulating the reaction temperature and pressure corresponding relation with different emergency discharge area.
