Water–Hydrocarbon Phase Equilibria with SAFT-VR Mie Equation of State

The study of water–hydrocarbon phase equilibria is very important for both scientific and industrial purposes. This work a thorough investigation the predictive capability SAFT-VR Mie equation state (EoS) aqueous hydrocarbon equilibria, including n-alkanes, alkenes, cycloalkanes, branched alkanes, aromatic hydrocarbons. For alkenes alkyl benzenes, induced association (solvation) with water considered. model able to capture correct equilibrium topology mixtures n-alkanes alkyl-benzenes as type III according Van Konynenburg Scott, but it not predict barometric shift alkanes longer than n-hexacosane due overshoot critical temperature water. Quantitative results solubility in light hydrocarbons such methane, ethane, ethylene, well mutual above minimum, are possible. latter predicted EoS similar other EoSs literature. Accurate predictions also reported pressure three-phase lines binary mixtures. Henry’s law constant often used prediction low-pressure vapor–liquid low calculations reasonable agreement experimental data constant, especially at higher temperatures. Qualitatively, captures maximum temperature, carbon number temperatures near shown be overall capable straightforward
