Abstract In this research, Joule–Thomson coefficients for pure, binary, ternary, and multicomponent systems are predicted using translated and consistent versions of Peng-Robinson and Redlich-Kwong equations of state. The former is claimed to be certainly the most accurate and the safest three-parameter cubic equation of state ever published. The obtained results are compared with the predictions provided by Peng-Robinson, Soave-Redlich-Kwong, Volume Translated Peng-Robinson, Volume Translated Soave-Redlich-Kwong, and Patel-Teja-Valderrama equations of state along with different alpha functions, including Peng – Robinson original form (1976), Coquelet et al. (2004), Haghtalab et al. (2011), Saffari – Zahedi (2013), Soave – Redlich – Kwong original form (1972), Ozokwelu – Erbar (1987), Trebble – Bishnoi (1987), Nasrifar – Bolland (2004), and Pina – Martinez et al. (2019). Furthermore, the obtained results are compared to the available experimental data. Moreover, the performance of translated-consistent Peng-Robinson and translated-consistent Redlich-Kwong equations of state is determined at low pressures (60 atm) up to high pressures (360 atm) in comparison to the other equations of state. The dependency of the Joule – Thomson coefficient as a function of the mole fraction has been investigated. To compare better, Joule–Thomson inversion curves are also depicted for a variety of systems, containing pure, binary, ternary, and multicomponent mixtures. The obtained results are compared to the experimental data, correlated results, and molecular simulations.

用于预测高压和高温下焦耳-汤姆逊效应的平移一致状态方程的评估比较

摘要 在这项研究中,使用 Peng-Robinson 和 Redlich-Kwong 状态方程的翻译和一致版本来预测纯、二元、三元和多分量系统的焦耳-汤姆逊系数。前者据称是有史以来最准确、最安全的三参数三次状态方程。将获得的结果与 Peng-Robinson、Soave-Redlich-Kwong、Volume Translated Peng-Robinson、Volume Translated Soave-Redlich-Kwong 和 Patel-Teja-Valderrama 状态方程以及不同的 alpha 函数提供的预测进行比较,包括Peng – Robinson 原始形式 (1976),Coquelet 等人。(2004),Haghtalab 等。(2011), Saffari – Zahedi (2013), Soave – Redlich – Kwong original form (1972), Ozokwelu – Erbar (1987), Trebble – Bishnoi (1987), Nasrifar – Bolland (2004), 和皮娜-马丁内斯等人。(2019)。此外,将获得的结果与可用的实验数据进行比较。此外,与其他状态方程相比,平移一致 Peng-Robinson 和平移一致 Redlich-Kwong 状态方程的性能是在低压 (60 atm) 到高压 (360 atm) 下确定的。已经研究了焦耳-汤姆逊系数作为摩尔分数的函数的相关性。为了更好地进行比较,还描绘了各种系统的焦耳-汤姆逊反演曲线,包括纯、二元、三元和多组分混合物。将获得的结果与实验数据、相关结果和分子模拟进行比较。与其他状态方程相比,平移一致 Peng-Robinson 和平移一致 Redlich-Kwong 状态方程的性能是在低压 (60 atm) 到高压 (360 atm) 下确定的。已经研究了焦耳-汤姆逊系数作为摩尔分数的函数的相关性。为了更好地进行比较,还描绘了各种系统的焦耳-汤姆逊反演曲线,包括纯、二元、三元和多组分混合物。将获得的结果与实验数据、相关结果和分子模拟进行比较。与其他状态方程相比,平移一致 Peng-Robinson 和平移一致 Redlich-Kwong 状态方程的性能是在低压 (60 atm) 到高压 (360 atm) 下确定的。已经研究了焦耳-汤姆逊系数作为摩尔分数的函数的相关性。为了更好地进行比较,还描绘了各种系统的焦耳-汤姆逊反演曲线,包括纯、二元、三元和多组分混合物。将获得的结果与实验数据、相关结果和分子模拟进行比较。已经研究了焦耳-汤姆逊系数作为摩尔分数的函数的相关性。为了更好地进行比较,还描绘了各种系统的焦耳-汤姆逊反演曲线,包括纯、二元、三元和多组分混合物。将获得的结果与实验数据、相关结果和分子模拟进行比较。已经研究了焦耳-汤姆逊系数作为摩尔分数的函数的相关性。为了更好地进行比较,还描绘了各种系统的焦耳-汤姆逊反演曲线,包括纯、二元、三元和多组分混合物。将获得的结果与实验数据、相关结果和分子模拟进行比较。
