An algorithm is proposed for conducting the phase-equilibrium calculation for a given mixture with a specified pressure, enthalpy, and composition. We use a second-order optimization method to maximize entropy, with the individual phase compositions

We present an algorithm for multiphase isenthalpic phase-equilibrium calculations. The algorithm addresses issues related to robustness and performance of isenthalpic flash, which sometimes get aggravated due to narrow boiling conditions. The isentha

Summary Phase-equilibrium calculations can be a time-consuming part of process simulators and compositional reservoir simulations. Various authors have presented encouraging speed improvements based on reduced methods that can lower the computational

The combination of successive substitution and the Newton method provides a robust and efficient algorithm to solve the nonlinear isofugacity and mass balance equations for two-phase split computations. The two-phase Rachford–Rice equation may some

The mixing of nonequilibrium phases has important applications in improved oil recovery and geological CO2-storage. The rate of mixing is often controlled by diffusion and modeling requires diffusion coefficients at subsurface temperature and pressur

The objective of the study has been to investigate whether cold-adapted microorganisms (CAMs) are metabolising hydrocarbons in situ at sub-zero temperatures. Since the summer 2001, soil temperatures and soil gas concentrations of oxygen (O2) and carb
