A fundamental equation of state is presented for the calculation of thermodynamic properties of chlorine. It is expressed in terms of the Helmholtz energy with the independent variables temperature and density. Based on the available experimental data from the literature, the equation is valid from the triple point temperature 172.17–440 K with a maximum pressure of 20 MPa. The quality of the equation is evaluated by comparisons with experimental measurements. Since the equation was developed in part for use in mixture models relevant for carbon capture and storage applications, special focus was also given to correct extrapolation behavior.

计算氯的热力学性质的基本状态方程

提出了用于计算氯的热力学性质的基本状态方程。它以具有独立变量温度和密度的亥姆霍兹能量表示。根据文献中可用的实验数据,该方程在三相点温度 172.17-440 K 和最大压力为 20 MPa 时有效。通过与实验测量值的比较来评估方程的质量。由于该方程部分是为了用于与碳捕获和储存应用相关的混合物模型,因此还特别关注校正外推行为。
