Abstract:

安全泄放是在失控条件下降低反应体系风险最为经济有效的技术措施之一。为了研究泄放口的设计,利用高性能绝热量热仪Phi-TECⅡ对质量分数38.6%的甲醇-乙酸酐体系进行了测试,得到热惯量为1.1条件下该体系的热行为参数。测试结果表明,该体系的起始分解温度为37℃,比反应热205.2kJ·kg-1;拟合得到温度与压力的关系基本符合Antoine方程,确定了反应体系的泄放类型属蒸汽体系;采用Leung方法和平衡速率模型ERM对该体系的安全泄放量和泄放能力进行了计算,求得泄放面积为1.36×10-3m2;低热惯量的Phi-TECⅡ可以为工艺放大的泄放设计提供准确、可靠的基础数据。
