This study provides insights into the experience gained from investigating thermodynamic behavior of well and reservoir fluids during acid gas injection (AGI) in a hydrocarbon field to enhance oil recovery (EOR) reduce greenhouse emissions. Unlike conventional water natural injection, AGI involves complicated phase changes physical property variations at various pressure-temperature (P-T) condi...

We use the model system ethanol–dodecane to demonstrate that giant critical fluctuations induced by easily accessible weak centrifugal fields as low 2000g can be observed above miscibility gap even far from point of a binary liquid mixture.

The effects of miscibility in interacting two-component classical fluids are relevant a broad range daily applications. When considering quantum systems, Bose–Einstein condensates provide well-controlled platform where the miscible–immiscible phase transition can be completely characterized. In homogeneous this is governed only by competition between intra- and inter-species interactions. Howev...

the main purpose of this investigation is to study the effect of near miscible co2 injection in different porous mediums on both lab and field scales. this effect can be traced by the change of two-phase gas-oil relative permeability curves. in this work, the experiments have been performed on three rock types (i.e. sandstone, dolomite, and artificial fractured sandstone) based on an incrementa...

Processing the experimental tie-lines in the miscibility gap of the Ba-Cu-Y ternary liquid alloys coupled with the Gibbs energies of the Ba-Cu and Cu-Y binaries estimated earlier has led to description of the Gibbs energy of the ternary melt and to the complete ternary phase diagram. The transformation of an open triangular simplex to the plane that can ease significantly optimization and calcu...

Early sedimentation in a liquid mixture off-critically quenched in its miscibility gap was investigated with a light attenuation technique. The time evolution of the droplet distribution is characteristic of an emulsion coalescing by gravitational collisions. This sedimentation behavior gave access to the phase-separating kinetics, and a crossover on the way toward equilibrium was observed, whi...

The large variation in miscibility of blends of polyolefins is related to the architecture of the chain molecules. In this paper we present first results of an approach in which small scale simulations of local interactions are combined with an analytical model for the thermodynamics, the Born-Green-Yvon lattice model, to predict phase diagrams of polyolefin blends from the pure component prope...

We report on the observation of controllable phase separation in a dual-species Bose-Einstein condensate with 85Rb and 87Rb. Interatomic interactions between the different components determine the miscibility of the two quantum fluids. In our experiments, we can clearly observe immiscible behavior via a dramatic spatial separation of the two species. Furthermore, a magnetic-field Feshbach reson...
