A New Diminishing Interface Method for Determining the Minimum Miscibility Pressures of Light Oil–CO2 Systems in Bulk Phase and Nanopores

Abstract: In this paper, a new interfacial thickness-based method, namely, the diminishing interface method (DIM), is developed to determine the minimum miscibility pressures (MMPs) of light oil–CO2 systems in bulk phase and nanopores. First, a Peng–Robinson equation of state (PR-EOS) is modified to calculate the vapor–liquid equilibrium in nanopores by considering the effects of capillary pressure and shifts of critical temperature and pressure. Second, the parachor model is coupled with the modified PR-EOS to predict the interfacial tensions (IFTs) in bulk phase and nanopores. Third, a formula of the interfacial thickness between two mutually soluble phases is derived, based on which the novel DIM is developed by considering two-way mass transfer across the interface. The MMP is determined by extrapolating the derivative of the interfacial thickness with respect to the pressure (∂δ/∂P)T to zero. It is found that the modified PR-EOS coupled with the parachor model is accurate for predicting the phase behavior and ...

Determination of local atomic displacements in CeO1-xFxBiS2 system

Abstract: We have used Bi and Ce L3-edges extended x-ray absorption fine structure measurements to study local structure of CeO1−xFxBiS2 system as a function of F-substitution. The local structure of both BiS2 active layer and CeO1−xFx spacer layer changes systematically. The in-plane Bi–S1 distance decreases (ΔRmax ~ 0.08 A) and the out-of-plane Bi–S2 distance increases (ΔRmax ~ 0.12 A) with increasing F-content. On the other hand, the Ce-O/F distance increases (ΔRmax ~ 0.2 A) with a concomitant decrease of the Ce–S2 distance (ΔRmax ~ 0.15 A). Interestingly, the Bi–S1 distance is characterized by a large disorder that increases with F-content. The results provide useful information on the local atomic displacements in CeO1−xFxBiS2, that should be important for the understanding of the coexistence of superconductivity and low temperature ferromagnetism in this system.
