摘要超压安全泄放的研究对于防止化工事故的发生意义重大,而这也是目前既有效又经济的安全措施之一。本文就失控条件下不同泄放类型系统的压力安全泄放进行研究。
本论文网利用高性能绝热量热仪(PHI-TEC II)分别对甲醇-乙酸酐体系和过氧化二叔丁基(DTBP)-甲苯体系进行测试,根据得到的温升速率、压升速率和压力随温度变化的关系, 结合测试曲线和反应物料的相关参数,判定甲醇-乙酸酐体系属于蒸汽体系,运用Leung法和ERM模型方法求得的泄放面积为9.73×10-4 m2,运用工程模型方法求得的泄放面积为2.37×10-3 m2;过氧化二叔丁基(DTBP)-甲苯体系属于混合体系,运用Leung法和OMEGA法求得的泄放面积为2.24×10-3m2,运用工程模型方法求得的泄放面积为1.85×10-2 m2。最后再利用这些实验数据开发出基于EXCEL平台的安全泄放辅助设计系统。19112

Title Research on Pressure Relief Aided Design System
for Exothermic Runaway Reaction
Abstract
The research on pressure relief for exothermic runaway reaction is significant for preventing some chemical accidents, which is also one of the most economic and effective measures. This paper studied the pressure safety relief of different relief types under uncontrolled conditions.
Based on Phi-TEC II, researches on Methanol/acetic anhydride and the Di-tert-butyl peroxide in Toluene were carried out. According to the data of temperature rise rate , pressure rise rate changing with temperature
and the relationship between temperature and pressure , the parameters of the reaction mass, the Methanol/acetic anhydride system is determined the steam system. According to Leung method and ERM method ,the relief area is 9.73×10-4 m2. According to the engineering modeling methods, the relief area is 2.37×10-3 m2.The Di-tert-butyl peroxide in Toluene is determined the hybrid system. According to Leung method and OMEGA method ,the relief area is 2.24×10-3m2.According to the engineering modeling methods, the relief area is 1.85×10-2 m2. Finally, these experimental data is used to develop a safety relief aided design system.
Keywords: exothermic runaway reaction, pressure relief, adiabatic calorimeter, relief area
