| 摘 要： | 本文提出一个以三参数立方型方程为基础的氨水体系状态方程。由同时拟合蒸汽压、汽相体积和液相体积确定的三个参数都是温度的函数。混合物的混合法则考虑了三分子相互作用对引力的贡献。四个交互作用参数处理成压力的线性关系后,在压力小于21atm下预测汽液平衡和热力学性质达到满意的结果。

A NEW EOS FOR AMMONIA WATER SYSTEM |
| |
| Abstract: | A new EOS for ammonia water system based on triparameter cubic equation is proposed. These three parameters, determined by fitting vapour pressure, vapour volume and liquid volume, are all function of temperature. The mixing rules for mixture are taken into consideration of the contribution of tri-molecule interaction to attraction. After four interaction parameters are treated to linear relation of pressure, the satisfactory results of VLE and thermodynamic properties of the systems predicted by the EOS are obtained at pressure less than 21 atm. |
