Modeling the solubility of light hydrocarbon gases and their mixture in brine with machine learning and equations of state

“…Attempts to model the vapor-liquid phase equilibria of non-hydrocarbon and hydrocarbon gases and brine solutions have always been considered by researchers due to the limited number of measurements. The activity coefficient, Henry's constant approach, and EOSs were widely used in thermodynamic models in order to gain information about the equilibrium conditions of non-hydrocarbon and hydrocarbon gases and pure water or aqueous electrolytes solutions 5,9,[31][32][33][34][35][36][37][38][39][40][41] . Although Henry's law can appropriately be utilized to estimate the solubilities, this approach has several drawbacks.…”
