VLE describes the distribution of components between vapor and liquid phases at equilibrium.
yiP = xiPisat
For non-ideal systems, activity coefficients (γ) are used:
yiP = xiγiPisat
Flash calculations determine phase fractions and compositions at equilibrium.
Σ(zi(Ki - 1)/(1 + V(Ki - 1)) = 0
Where zi is feed composition and Ki is the equilibrium ratio (yi/xi).
