摘要:以汽相中各物质真实的摩尔分率归一方程作为计算温度的目标函数,提出了一个适合于缔合物系的泡点迭代计算方法。在校正了醋酸组分的汽相缔合效应后,对醋酸-水-醋酸乙烯酯三元物系的复杂精馏塔进行了模拟计算,结果与实测数据相吻合。
A new bubble point iterative calculation method which is suitable to associa-tion mixture is developed.In the method the real vapor mole fraction constraint equation istaken as the objective function to search the temperature. The method was examined by sim-ulating the complex distillation about acetic acid-water-vinyl acetate mixture system,inwhich,the associating effects of acetic acid in vapor phase is considered.The simulated results agree well with industrial operation data.
