| 摘 要： | 利用 Ｐ Ｒ、 Ｓ Ｒ Ｋ、 Ｈ Ｋ、 Ｐ Ｔ 状态方程（ Ｅ Ｏ Ｓ）计算 Ｃ Ｏ２ 、 Ｃ４ Ｈ９ Ｏ Ｈ、 Ｈ２ Ｏ 纯组份的饱和性质及 Ｃ Ｏ２ 的压缩因子。结果表明， Ｐ Ｔ 方程对水、二氧化碳的蒸汽压及密度预测较佳。对丁醇的密度推算， Ｐ Ｔ 方程最佳， Ｐ Ｔ 方程对丁醇的饱和蒸汽压预测一般。考察了 Ｐ Ｔ 方程参数的影响，指出应根据相平衡的温度范围选取相应的 Ｐ Ｔ 方程参数。对 Ｃ Ｏ２ Ｃ４ Ｈ９ Ｏ Ｈ Ｈ２ Ｏ 体系相平衡的研究宜选用 Ｐ Ｔ 方程。

| Abstract: | The Equations of State, PR, SRK, HK and PT EOS are used to calculate compress factor of carbon dioxide and the saturated properties of pure substances including carbon dioxide, butanol, water. It is showed that among the Equations of State, PT EOS is the best to calculate the vapor pressure and density for water and carbon dioxide. PT EOS is the best to calculate the density of butanol, but it is not very good for PT EOS to calculate the vapor pressure of butanol. The effect of the parameters of PT EOS is examined. It is found that the parameters should be determined according to the temperature range interested. The PT EOS is the most suitable to the calculation of the CO 2 C 4H 9OH H 2O system. |
