【摘要】 本文从统计热力学理论出发，结合ｖａｎｄｅｒＷａａｌｓ－Ｐｌａｔｔｅｅｕｗ理想固溶休假设。给出ＨＦＣ１５２ａ和ＨＣＦＣ１４１ｂ简单气体水合物相平衡计算模型，并进行计算。计算结果与实验数据进行比较，很好吻合，正确反映了简单致冷剂水合物的相平衡规律。本研究为进一步混合气体水合物相平衡计算打下基础。更多还原

【Abstract】 In this papers the phase equilibrium experimental data of simple gas hydrates ofHFC-152a and HCFC-141b are presented and a model of phase equilibrium calculation forgas hydrates has been formulated based on van der Waals-Platteeuw’s theory of ideal solidsolution. The phase equilibria of HFC-152a and HCFC-141b gas hydrates was calculatedwith established model, and the calculation results and experiment data are fitted very well.It is shown that the calculation model can well depict the phase equilibrium characteristicsof gas hydrates and provide a base for calculation for mixed gas hydrate phase equilibria.更多还原
