Abstract
This study aims to evaluate the performance of two new equations of state, namely tc-PR and tc-RK EOSs. In doing so, the performances of these equations of state are examined by predicting Joule-Thomson coefficients and Joule-Thomson inversion curves of multicomponents at high pressure and high temperature. In this regard, 3 natural gas samples and 2 gas condensate samples are utilized. The obtained results have been compared to predictions performed by popular cubic equations of state, including Peng-Robinson (PR), Soave-Redlich-Kwong (SRK), volume translate PR (VTPR), volume translate SRK (VTSRK), and PTV EOSs. Furthermore, the impacts of temperature and pressure on Joule-Thomson coefficient of mixtures have been also investigated.
