Application of Crossover Theory to the SAFT-VR Equation of State: SAFT-VRX for Pure Fluids
The molecular-based SAFT equation of state has proven to be very versatile in the prediction of fluid phase equilibria. However, in common with all analytic equations of state, SAFT exhibits classical behavior in the critical region rather than the nonanalytical, singular behavior seen in real fluids. As a result, accurate agreement over the whole phase diagram cannot be obtained and must be lo...
متن کاملObservations of Sludge Formation in Group I Base Stock for Lubricants and Thermodynamic Modeling with the SAFT Equation of State
Varnish and sludge formation are considered as one of the most common problems in lubrication and hydraulic systems. In order to simulate the condition of sludge formation, base stock lubricant (Group 1 API) has been selected and exposed to heat in a laboratory setup. Sludge formation process accelerated in the laboratory scale and solid liquid equilibrium data were extracted. Then solid-liquid...
متن کاملApplication of SAFT–VRX to binary phase behaviour: alkanes
In previous work, we developed the crossover SAFT–VR equation of state (SAFT–VRX) for pure fluids by following the crossover approach proposed by Kiselev. The SAFT–VRX equation was shown to be very accurate in the prediction of PVT and phase behaviour for both nonassociating and associating fluids. In particular, simple expressions for the potential model parameters for the n-alkane homologous ...
متن کاملA density functional theory for vapor-liquid interfaces using the PCP-SAFT equation of state.
A Helmholtz energy functional for inhomogeneous fluid phases based on the perturbed-chain polar statistical associating fluid theory (PCP-SAFT) equation of state is proposed. The model is supplemented with a capillary wave contribution to the surface tension to account for long-wavelength fluctuations of a vapor-liquid interface. The functional for the dispersive attraction is based on a nonloc...
متن کاملMinimum Miscibility Pressure Using the Multiple Mixing-cell Combined with the PC-SAFT Equation of State
The minimum miscibility pressure (MMP) is one of the crucial and substantial parameters in the gas injection projects for enhanced oil recovery (EOR). This parameter indicates the minimum pressure at constant temperature and composition conditions for reaching 100 percent of the oil production recovery which leads to a huge economic income. Therefore, an inaccurate prediction of the MMP may lea...
