Run Module

The calculation of multiphase equilibrium is also called multiphase P-T flash calculation. This module of cloud computing performs the calculation of multiphase equilibria in the systems containing more than two phases: a gas phase, a liquid hydrocarbon phase, an aqueous phase and solid phase should the system exist multiple phases. At certain conditions, the system exists a CO₂-rich liquid phase. The equilibrium state is characterized by minimizing the Gibbs free energy. The method established by Michael L. Michelsen (1980) is adopted.

The table below shows the prediction results of vapor-liquid 1(HC liquid)-liquid 2(aqueous phase)-liquid 3(CO₂-rich liquid phase) equilibria.
