摘要: Abstract The current study reports original vapour-liquid equilibrium (VLE) for the system {CO2 (1) + 1-chloropropane (2)}. measurements have been performed over entire pressure-composition range T = (303.15, 313.15 and 328.15) K isotherms. values obtained used comparison of four predictive approaches, namely equation state (EoS) Peng Robinson (PR), Soave modification Benedict–Webb–Rubin (SBWR) EoS, Critical Point-based Revised Perturbed-Chain Association Fluid Theory (CP-PC-SAFT) Conductor-like Screening Model Real Solvents (COSMO-RS). It has demonstrated that three EoS under consideration yield similar qualitatively accurate predictions VLE, which is not case COSMO-RS model examined. Although CP-PC-SAFT exhibits only minor superiority in with PR SBWR predicting VLE consideration, its relative complexity can be justified when taking into account thermodynamic phase space and, particular, considering liquid densities sound velocities a wider pressure-volume-temperature range.
