Phase behavior experiments and PVT modeling of DME-brine-crude oil mixtures based on Huron-Vidal mixing rules for EOR applications

DME-partitioning between a live oil and 3.5 wt% brine at 343 K: marker points correspond to in-house experimental data measured at 10,000-14,000 kPa; solid lines correspond to the computed results using PR78 EOS with Huron-Vidal mixing rule at 12,000 kPa. DME-partition coefficient decreases as DME-mole fraction in hydrocarbon phase increases.114
