二元氮──烃类与氮──氟里昂低温混合工质的汽液固相平衡分析

Analysis of Vapor-Liquid-Solid Equilibria of Binary Cryogenic Mixtures Containing Nitrogen and Alkanes or Nitrogen and Freon

该文根据相平衡理论，用ＰＲ方程计算了二元氮—烃类与氮—氟里昂低温混合工质的汽、液、固相中各组元的逸度系数及逸度，分析了二元氮—烃类与氮—氟里昂混合工质的汽液固相平衡，揭示了二元氮—烃类与氮—氟里昂混合工质“冰堵”的机理。

The PR equation is used to calculated the fugactity coefficients and fugacities of the vapor phase, liquid phase and solid phase of binary cryogenic mixtures containing nitrogen and alkanes or nitrogen and freon. Then, the vapor-liquid-solid equilibria of these mixtrues are calculated and the cologging mechanism of these mixtures useing in a Joule -Thomoson cryooooler is revealed.
