... A g ) is the maximum mole fraction of a gas component in aqueous phase; P g is a partial pressure of a gas component; H is the Henry's constant as a function of component and temperature ( Yaws 2003 ). We compute the maximum dissolved mole fraction of a gas component in liquid organic...

... to estimate the composition of the vapor and aqueous phases. The PRSV is a modification of the Peng-Robinson equation of state. We use an activity-coefficient based mixing rule for the thermodynamic calculations. A volume shift procedure is applied to improve liquid density. upstream oil & gas salt...

In our mathematical conceptual model, salt is treated as an additional "component" to the aqueous phase, based on the following physical considerations: salt is transported only within the aqueous phase by advection and diffusion, and also subject...
