| 摘 要： | 气液平衡计算是化学过程中的一项十分重要的计算。但目前的教学中并没得到相应的强调与详细的阐述。本文讨论了低中高压下的气液平衡计算的特点与之间的关系,通过程序设计对双组分系统进行了计算,并将计算结果进行了对比,采用PR方程设计的适于高压下气液平衡计算的方法与程序用于中低压下的计算也得到了较好的一致性。本研究结果可使气液相平衡内容的教学更为丰富与系统。

| Abstract: | The VLE calculation is a kind of very important calculation for chemical processes. But in the present textbooks, it hasn＇t been well strengthened and systemically illustrated. Here, the VLE calcula- tions under low, moderate and high pressures and their relations are discussed. With C＋ ＋ programming, the VLE calculations for a binary system are performed and the calculation results are discussed. The calculation method and the C＋ ＋ program designed for high pressure VLE is still available for low or moderate pressure VLE calculations. The presented work can make the teaching contents richer and more systematic. |
