Abstract Equations of state are presented for the five binary mixtures NH3 + Ar, NH3 + CH4, NH3 + H2, NH3 + N2, and NH3 + CO. These mixture models were fitted to experimental data. The models are explicit in the reduced Helmholtz energy as a function of temperature, density, and composition. The equations of state can be used to calculate all thermodynamic properties over the entire fluid region covering vapor, liquid, phase equilibria, and supercritical states. Comparisons to literature data are presented to validate the new models. Most of the experimental data are reproduced within their experimental uncertainty. The range of validity is linked to the available data for each system; however, reasonable extrapolation behavior was ensured with the use of constraints during the fitting process. For an additional seven binary mixtures (NH3 + Cl2, NH3 + DEA, NH3 + HCl, NH3 + H2S, NH3 + MEA, NH3 + O2, and NH3 + SO2) standard mixing rules were used, although no experimental data were available for validation.

含氨混合物的基本热力学模型

摘要 给出了 NH3 + Ar、NH3 + CH4、NH3 + H2、NH3 + N2 和 NH3 + CO 五种二元混合物的状态方程。这些混合物模型适合实验数据。这些模型在作为温度、密度和成分的函数的减少的亥姆霍兹能量中是明确的。状态方程可用于计算整个流体区域的所有热力学性质，包括蒸气、液体、相平衡和超临界状态。提供了与文献数据的比较以验证新模型。大多数实验数据都在其实验不确定性范围内重现。有效性范围与每个系统的可用数据相关联；然而，在拟合过程中通过使用约束确保了合理的外推行为。对于另外七种二元混合物 (NH3 + Cl2,
