Hybrid Newton–Successive Substitution Method for Multiphase Rachford-Rice Equations

Hybrid Newton–Successive Substitution Method for Multiphase Rachford-Rice Equations

In multiphase (≥3) equilibrium calculations, when the Newton method is used to solve the material balance (Rachford-Rice) equations, poorly conditioned Jacobian can lead to false convergence. We present a robust successive substitution method that solves the multiphase Rachford-Rice equations sequen...
