the equilibrium solubility data of co2 in the various aqueous blends of triisopropanolamine (tipa) + monoethanolamine (mea) with the total alkanolamine concentration of 2 mole / dm3 were measured at the temperatures of 30, 40, 50, 60 and 70 oc and co2 partial pressures below 100 kpa. the experiments were done in an atmospheric gas absorption system and the amount of absorbed co2 was measured wi...

Developing a modeling method for determining the solubilities of metal complexes in supercritical CO2 is crucial designing an effective CO2-based deposition technique. This study aimed to model solubility ferrocene, typical precursor metallic iron, CO2, which was achieved using perturbed-chain statistical associating fluid theory (PC-SAFT) conjunction with experimental data organic solvents. Pu...

Modelling of CO2 solubility in aqueous solutions potassium lysinate (LysK) is mainly hindered by scarcity experimental vapor–liquid equilibrium data and lack chemical constants associated to the reaction mechanism for CO2/LysK/H2O system. Therefore, Kent-Eisenberg (KE) correlation stands out from literature, being among most used approaches description partial pressure at different loadings. In...

During this study, a comprehensive investigation of low salinity water alternating CO2 injection was performed for enhanced oil recovery in oil-wet carbonate reservoirs. A synergy interfacial mechanisms such as IFT, wettability alteration, solubility, swelling, shielding effect, and rock dissolution considered two three-phase systems. Results showed that the monovalent ions, NaCl or KCl, inhibi...

Utilization of ionic liquids (ILs) for carbon dioxide (CO2) capture is continuously growing, and further understanding the factors that influence its solubility (notably new ILs) crucial. Herein, CO2 absorption two 1,2,4-triazolium-based ILs was compared with imidazolium-based Ils different anions, namely bis(trifluoromethylsulfonyl)imide, tetrafluoroborate, glycinate. The capacity determined u...
