Equation of state for the systems containing aqueous salt: Prediction of high pressure vapor-liquid equilibrium
Baseri H, Lotfollahi MN, Asl AH
An equation of state (EOS), which is based upon contributions to the Helmholtz energy, is presented for systems containing aqueous electrolyte solutions at high pressure. The Peng-Robinson equation of state is used to provide the Helmholtz energy of a reference system. The electrolyte terms consist three terms containing a modified Debye-Huckel term for long-range electrostatic interactions, the Born energy contribution for electrostatic works and a Margules term for short-range electrostatic interactions between ions and solvents. The binary and ternary interaction parameters of the equation of state are obtained by experimental osmotic coefficient data. Systems that were studied here are (water+NaCl+SC-CO2), (water+NH4Cl+SC-CO2), (water+Na2SO4+SC-CO2) and (water+methanol+NaCl+SC-CO2). It is found that the proposed equation of state is able to accurately represent the experimental data over a wide range of pressure, temperature and salt concentration.
Keywords: Equation of State; Electrolyte Solution; Vapor-liquid Equilibrium
