Traditionally, SAFT EoS parameters are fit to pure component pressure-volume-temperature (PVT) (density) data and vapor pressure data. We have recently combined the PC-SAFT EoS with entropy scaling theory to correlate and predict the viscosity of ILs and IL mixtures. We found that the PC-SAFT EoS parameters for ionic liquids regressed to PVT data can sometimes lead to relatively large deviations in the viscosity correlations, especially at high pressure. Here, we investigate the effect of including viscosity data along with PVT data for the PC-SAFT parameter regression of two series of 1-n-alkyl-3-methyl imidazolium ionic liquids ([C<em>_n</em>MIm][Tf₂N] and [C<em>_n</em>MIm][BF₄]). From analyzing the Pareto fronts, the inclusion of viscosity data to PVT data for PC-SAFT parameters resulted in only a small loss in accuracy for the density, but with much improved viscosity correlations through entropy scaling. We found that the parameter sets obtained from density and viscosity data regression are less prone to numerical pitfalls, i.e. fictitious SAFT critical points, than the parameter sets obtained from PVT data alone. In addition, the predicted (<em>k_ij</em>=0) phase equilibrium (VLE) of ionic liquids and mixtures with CO₂, CH₄, and water were equal to, if not better than the predictions using PVT data alone. Overall, the use of pure PVT and viscosity data in the parameterization of PC-SAFT yields a more widely applicable prediction method for both thermodynamic and transport properties.</div></div>","PeriodicalId":12170,"journal":{"name":"Fluid Phase Equilibria","volume":"595 ","pages":"Article 114427"},"PeriodicalIF":2.8,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143682467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One promising solution for underground energy storage is the use of subsurface CO₂ hydrate capsules, which act as impermeable vessels that store compressed fluids and discharge them upon need. However, as part of the proof-of-concept study of this technology, the feasibility of constructing such vessels, e.g. CO₂ hydrate capsules, has yet to be demonstrated. This work employed CO₂ gas injection assisted by chemical solution into partially water-saturated sand sediments to synthesize CO₂ hydrate capsules. The concentrations of chemical solutions (THF, CP and DIOX) were screened out in the gas/liquid/sand system in terms of kinetic promotion, using a rocking cell. Separately, experiments were carried out with a new high-pressure chamber set-up that quantified the effects of water saturation and chemical promoters on the efficiencies of CO₂ hydrate synthesis in confined partially water-saturated sand. Results on the gas/liquid/sand system showed that 0.025 water/CP weight ratio CP solution and 1.3mol% THF solution induced the largest pressure drops of 18.4 ± 0.2 bar and 16.7 ± 0.1 bar, respectively, indicating the most promoted CO₂ hydrate formation kinetics. Results with the pressure chamber showed three stages during slow CO₂ gas injection: (1) initial pressure “build-up stage”; subsequent (2) CO₂ gas “uptake stage”; and (3) CO₂ injection “closing stage”. CO₂ hydrate formation kinetics of CO₂ hydrate retention percentage (S_CO2) and CO₂ hydrate density (ρ_CO2) were directly proportional to the initial water saturation (6.0–76.7%). Injection of THF or CP solutions increased S_CO2 by 16.5% or 18.5%, and ρ_CO2 by 74.5% or 128.3% compared to injection of water. The best performances were obtained at a fluid pressure of 27.0 bar, with a 0.025 water/CP solution-assisting CO₂ gas injection, in sediment with an initial water saturation of 32.6% and porosity of 44.6%, giving rise to S_CO2 of 67.2% and ρ_CO2 of 80.6%.
