Systematic studies on the vapor-liquid equilibria (VLE) and conductometric properties of aqueous solutions of model surface-active ionic liquid 1-dodecyl-3-methylimidazolium bromide ([C12mim]Br) are performed in the absence and presence of a large series of electrolytes in order to achieve a deeper understanding about the molecular mechanism behind the specific salt effect on the aggregation be...

The objective of the present work is to investigate full phase diagram a binary system composed carbon dioxide and heavy paraffin. An alkane with an odd number was chosen since mixtures paraffins crystallize in orthorhombic structure like pure do. normal-heptadecane taken into consideration for this study as it has melting temperature close ambient condition (295 K). consists measuring both flu...

This study reports liquid–liquid equilibrium (LLE) and liquid–liquid–liquid (LLLE) data for binary (phenol + n- dodecane, or n -hexadecane) ternary (water phenol systems measured under atmospheric pressure. The compositions of coexisting phases were determined with analytical cloud point methods at temperatures 298 K – 353 K. Non–Random Two–Liquid (NRTL) excess Gibbs energy model was employed t...

Phase equilibria of a square-well fluid in planar slit pores with varying slit width are investigated by applying the grand-canonical transition-matrix Monte Carlo (GC-TMMC) with the histogram-reweighting method. The wall-fluid interaction strength was varied from repulsive to attractive such that it is greater than the fluid-fluid interaction strength. The nature of the phase coexistence envel...

5 Germany 6 In a recent article, Zhang and Duan [1] presented a new potential model 7 for carbon dioxide (CO 2). It consists of three Lennard-Jones (LJ) sites to 8 account for repulsion and dispersion and three distributed partial charges to 9 describe the quadrupolar interaction. The molecular model is rigid and ro-10 tationally symmetric around the molecular axis. In that work [1], simulation...

Efficient and robust phase equilibrium computation has become a prerequisite for successful large-scale compositional reservoir simulation. When knowledge of the number of phases is not available, the ideal strategy for phase-split calculation is the use of stability testing. Stability testing not only establishes whether a given state is stable, but also provides good initial guess for phase-s...
