VLE describes the distribution of components between vapor and liquid phases at equilibrium.
For non-ideal systems, activity coefficients (γ) are used:
Flash calculations determine phase fractions and compositions at equilibrium.
Where zi is feed composition and Ki is the equilibrium ratio (yi/xi).
