Multicomponent CO/sub 2//water/hydrocarbon phase behavior modeling: A comparative study
Phase behavior predictions of the Peng-Robinson (PR) equation and the Kleintjens-Koningsveld (KK) equation, a lattice-gas model, are compared for pure CO/sub 2/, water, methane, n-butane, n-octane, n-decane, and several binary and ternary mixtures of these components. The KK equation is more accurate than the PR equation for predicting the saturated liquid densities of pure fluids. The two equations are comparable in predictions of binary pressure/composition phase diagrams and ternary-composition phase diagrams. Thus for these properties, the PR equation is preferred because it is a simpler equation, has fewer adjustable parameters, and has parameters available for more systems than the KK equation.
