Abstract: New analytical correlations for the phase equilibrium constants (K-values) are proposed. They take into account the effect of fluid composition. The model more accurately describes the phase behavior of multicomponent solutions. The approach allows to build a thermodynamically consistent model. It's convenient for numerical simulation of transport in porous media: reduced the required computational resources, increases the reliability of the accounts.

Keywords: phase equilibrium constants, equation of state, phase transition.
