采用绝热加速量热仪对13%过氧乙酸溶液进行了热危险性测试,并采用伪逆矩阵法和热惰性因子对实验获得的热分解特性参数进行了绝热修正,得出绝热条件下13%过氧乙酸溶液初始放热温度为45.25℃,最大压强为1.31 MPa,最高温升速率温度为113.1℃.在此基础上,得到安全泄放的危险参数,并根据过氧乙酸测试分解温升曲线判断出该泄放系统为非缓和混合系统,采用DIERS方法和Omega方法对某工厂一储罐进行安全泄放面积计算,得到安全泄放面积、热惰性因子及相关结论.
13% actetic hydroperoxide is investigated by Accelerating Rate Calorimeter (ARC). Judged by ARC test, inital exothermic temperature is 45.25℃ , the maximum pressure is 1.31 MPa, and the maximum self-heating rote temperature is 113.1 ℃. The experiment results indicate that the acetic hydroperoxide is of obvious hazard. Based on above, the dangerous parameters are calculated when need to release, and the relief system is non - tempered hybrid system, which judged by ,the curve of temperature is pressure. In the end, the relief system size of an acetic hgdro peroxide tank can be calculated using the methods of DIERS and omegas.
