摘要：

Gas solubility data of methane (CH4) in aqueous electrolyte solutions were measured using the static synthetic method in a temperature range from 313 to 373 K, at pressures up to 10 MPa, and with molalities up to 8 mol.(kg of water)(-1). The experimental P-x data were used to fit interaction parameters for an equation of state approach, which consists of a combination of the predictive Soave-Redlich-Kwong (PSRK) group contribution equation of state and the LIFAC method for the prediction of vapor-liquid equilibria in systems with strong electrolytes. Furthermore, Henry coefficients were derived from these experimental P-x data and compared to the results of the extended PSRK model.
