摘    要:汽液相平衡计算是化工热力学教学中的一个重点和难点。以“化学”理论和Hayden—O’Connell(HOC)方法为基础,关联水+醋酸体系的等压汽一液平衡数据。结果表明,该缔合相平衡模型的计算值与文献值吻合。以醋酸+N,N-二甲基甲酰胺(DMF)体系汽-液平衡数据为例,分别采用vanLaar,Wilson及NRTL模型对醋酸-DMF物系的汽液平衡数据进行关联,得到相应的模型参数,为汽液相平衡教学提供一种新思路。

关 键 词:汽液相平衡  电算化  数学模型  醋酸  教学方法

Abstract:Calculation of vapor-liquid equilibrium (VLE) is a focus and difficulty for the teaching of chemical engineering thermodynamics. Based on the chemical theory and the Hayden- O'Connell (HOC) method, isobaric VLE data of the system water+acetic acid was connected. The results showed that the predicted value obtained in this way agree with the literature value. As the example, van Laar, Wilson and NRTL models were used during the date correlation for the experimental VLE data of the system acetic acid+N, N-dimethylformamide (DMF), and model parameters were obtained. This provids a new teaching idea for VLE.
Keywords:vapor-liquid equilibrium(VLE)  computerization  mathematical model  acetic acid  teaching method
