A New method, based on dynamic method of double phase circulation for measurement of vapor liquid equilibrium data of salt-containing system, is present,and a new apparatus developed. To solve the problems existing in the common determination method for salt-containing vapor liquid equilibrium , our work is based on the principle of double phase circulation method and the determination procedure is divided into two steps. In the first step, the quasi-static method is used to measure the bubble point line data (t,x) which does not require composition analysis,and in the second step, by using the same apparatus CS- Ⅱ multipurpose VLE determination apparatus, the dew point line data (t, y) of the same constant salt concentration in equilibrium liquid phase is determined. The new VLB determination apparatus with a pump-like stirrer can make the circulation so steady that it can avoid effectively the fluctuation and the rush of the liquid flow which often happens when double phase circulation apparatus are used for salt-containing systems. The error equation of quasi-static method for the bouble point measurement of salt-containing system is deduced from the relationship of material balance concerned,the verification work was done experimentally, including the examination of the applicability of the new apparatus in saturated salt-containing system and the determination of VLE data of CaCl2-acetone(1)-methanol(2) system at normal pressure and 5% CaCl2 concentration in equilibrium liquid phase. The experimental data agree finely with literature data.

针对含盐体系汽液平衡测定的特点及常用测定仪器和方法中的问题,改制了具有沸点仪和双循环平衡釜双重功能CS-Ⅱ型VLE测定仪,并以拟静态法测定了含盐体系汽液平衡的泡点线和平衡液相恒盐浓度下的露点线.新测定仪能避免用双循环仪器时极易出现的流动不稳定性和爆沸现象.成功地测定了氯化钙平衡液相浓度为5%的CaCl_2-丙酮(1)-甲醇(2)体系的汽液平衡数据.

A new method independant on the composition analysis for measuring VLE data of binary system is developed, in which the bubble point curve is measured with ebulliometeric method, and the temperatures of dew point and bubble point with two-leaned-ebulliometer,and the dewpoint curve is obtained via compositions at dew point temperature determined by bubble point curve. A two-leaned-ebulliometer is designed to satisfy the coupling method, and a set of VLE data for methanol-acetone syatem at 1.01325×10~5 Pa is measured...

A new method independant on the composition analysis for measuring VLE data of binary system is developed, in which the bubble point curve is measured with ebulliometeric method, and the temperatures of dew point and bubble point with two-leaned-ebulliometer,and the dewpoint curve is obtained via compositions at dew point temperature determined by bubble point curve. A two-leaned-ebulliometer is designed to satisfy the coupling method, and a set of VLE data for methanol-acetone syatem at 1.01325×10~5 Pa is measured by the combination with the bubble point curve determined by ebulliometar to test the method and apparatus. The data measured with an average derivation of 0.0051 for vapor concentration, which pass the thermodynamic consistency test with Barker method, are in good agreement with those from literatures.

本文提出一种不依赖组成分析测定二元汽液平衡数据的新方法。该法用沸点计法测定泡点线,用双斜式沸点仪测定露点和泡点温度,并通过泡点线确定露点组成从而得到露点线。 本工作还设计了适用于该方法的双斜式沸点仪。为验证方法和考核仪器,与斜式沸点仪测定的泡点线结合,测定了一套完整的常压甲醇-丙酮体系汽液平衡数据;并用Barker方法进行逐点热力学一致性检验,汽相浓度平均偏差|δ|-0.0051,该套数据同文献数据亦吻合良好。
