...A.A. Shinta; Abbas Firoozabadi Summary An association model has been incorporated in the Peng-Robinson equation of state (PREOS) to use the combined model for water/reservoir crudes phase-behavior calculations. The interaction coefficients between H2O and hydrocarbons follow a simple relationship...

The EOS modelling software exported the compositions variation with depth and used as input in the simulator to capture the physical fluid behavior in the reservoir. The rock properties were reverted to the values from lab measured SCAL data – Swcr was reverted to 30...

... will react with water to form hydrates according to G + NH H2O = G+NH H2O, where NH is the hydration number. Of particular interest are hydrates formed by hydrocarbon gases when G is an alkane. Natural hydrates in geological systems also include CO2, H2S and N2 as guests. Vast amounts of hydrocarbons...

..., we employed a quaternary liquid system composing of hexadecane (C16), n-butanol (NBA), water (H2O), and isopropanol (IPA). Measured equilibrium phase compositions and IFTs are reported. The reported phase behavior of the quaternary system shows that the H2O-rich phase should represent the gas phase...

The Predictive-Soave-Redlich-Kwong (PSRK) Equation of State as implemented in Aspen Plus® and AQUAlibrium have been used to describe the complex phase behavior of these systems. Results have been compared with vapor-liquid equilibrium experimental data to evaluate...

... the general local condensation behavior at Sec II, III and IV. However, as more thermodynamic data of ternary HF- H2O-HC is available, the effect of the hydrocarbon on the condensation of HF acid can be further studied. In Sec I, because of the relatively high HF content in the vapor phase, the presence...

... behavior of crude oils and gases. The predictions worsen as the liquid phase becomes more nonideal, as in the calculations of aqueous-phase behavior, and modifications to the original cubic equation of state are required to produce acceptable results. Many systems of interest to the petroleum industry...

..., which form three liquid phases in equilib- rium at ambient conditions. The C16/NBA/H2O system gives appropriate phase behavior when isopropanol (IPA) or sodium chloride (NaCl) is added to the mixtures. Adding IPA or NaCl changes the compositions of the three equilibrium phases that form in a way...

..., not the phase behavior. For example, a pseudo-component may be used to model kinetically similar hydrocarbons with widely varying boiling points. Reliable phase behavior models are therefore difficult to develop, and it is natural to expect sensitivities to the chosen formulation. We again use the VKC to study...
