摘要：用气相色谱法测定了二甲醚 甲醇二元系统在20、50、80、100℃温度下,0～1 45MPa压力范围内汽液相平衡数据。对测定数据进行热力学计算,气相采用PR方程,液相采用NRTL方程。模型计算值与实验值符合良好。采用单纯型法回归出二元系统在上述温度下的NRTL方程参数。汽液相平衡数据经Herington面积法检验满足热力学一致性。
Isothermal VLE data for dimethyl ether/methanol binary at 20℃, 50℃, 80℃ and 100℃ have been measured by using the method of gas chromatography. Thermodynamic calculation of the experimental data has been carried out by using PR equation for gas phase and NRTL equation for liquid phase, and the calculated data accord well with the experimental data. The parameters of NRTL model for this binary system at the aforementioned temperatures, expressed as function of the temperature, have been optimized by simplex method. The VLE data satisfy thermodynamic consistency by Herington method.
