“…[3], the typical equilibrium subsurface conditions is based on a mean surface temperature of 293.15K, a geothermal gradient of 35K·km 1 , and a hydrostatic pressure gradient of 10.5MPa·km 1 . For the temperature and pressure range of disposal of CO 2 in deep saline aquifers, available experimental data can nearly satisfy the needs of the calculation for the sequestration capacity, but the reliability of the (a) CO 2 323.15K [32]; 323.15K [20]; 323.15 [28]; 323.15K [9]; 323.15K [23] (b) H 2 O 323.15K [32]; 323.15K [20]; 323.15 [28]; 323.15K [11]; 323.15K [23] Figure 1 Experimental data for the mutual solubilities of carbon dioxide and water data from different sources should be further validated.…”

To study the feasibility of CO 2 geological sequestration, it is needed to understand the complicated multiple-phase equilibrium and the densities of aqueous solution with CO 2 and multi-ions under wide geological conditions (273.15 473.15K, 0 60MPa), which are also essential for designing separation equipments in chemical or oil-related industries. For this purpose, studies on the relevant phase equilibria and densities are reviewed and analyzed and the method to improve or modify the existing model is suggested in order to obtain more reliable predictions in a wide temperature and pressure range. Besides, three different models (the electrolyte non random two-liquid (ELECNRTL), the electrolyte NRTL combining with Helgeson model (ENRTL-HG), Pitzer activity coefficient model combining with Helgeson model (PITZ-HG)) are used to calculate the vapor-liquid phase equilibrium of CO 2 -H 2 O and CO 2 -H 2 O-NaCl systems. For CO 2 -H 2 O system, the calculation results agree with the experimental data very well at low and medium pressure (0 20MPa), but there are great discrepancies above 20MPa. For the water content at 473.15K, the calculated results agree with the experimental data quite well. For the CO 2 -H 2 O-NaCl system, the PITZ-HG model show better results than ELECNRTL and ENRTL-HG models at the NaCl concentration of 0.52mol·L 1 . Bur for the NaCl concentration of 3.997mol·L 1 , using the ELECNRTL and ENRTL-HG models gives better results than using the PITZ-HG model. It is shown that available experimental data and the thermodynamic calculations can satisfy the needs of the calculation of the sequestration capacity in the temperature and pressure range for disposal of CO 2 in deep saline aquifers. More experimental data and more accurate thermodynamic calculations are needed in high temperature and pressure ranges (above 398.15K and 31.5MPa).

“…The extraction of Co and Mn was hardy extracted in the only and binary system excepting use of D2EPA. Contacting CO 2 in the high pressure and temperature, pH of aqueous is about 2.8-2.9 [8]. Also, Cayenx 272, PC88A and D2EHPA are known kind of acid extractant.…”

EKSTRAKCJA KOBALTU Z ZUŻYTYCH KATALIZATORÓW CMB PRZY UŻYCIU NADKRYTYCZNEGOThe metal extraction from spent CMB catalyst using supercritical CO 2 (scCO 2 ) was investigated with single organic system, binary organic system and ternary organic system to extract metal ions. Leaching solution of spent CMB catalyst containing 389 mg L −1 Co 2+ , 187 mg L −1 Mn 2+ , 133 mg L −1 Na + , 14.97 mg L −1 Ca 2+ and 13.2 mg L −1 Mg 2+ . The method consists of scCO 2 /ligands complexation process and metal extraction process at 60 • C and 200bar. The result showed the Co and Mn was selectively extracted from Mg, Ca and Na in the ternary system of mixture of Cyanex272, DEA and Alamine304-I.

“…As shown in Figure 2a, the fundamental process of binary diffusive mixing is captured by all of the codes, with slight differences in diffusion rate. Note in Figure 2b that the pressure in the system increases, a result of the effect on gas density of the mixing between CO 2 and CH 4 . In direct relation to the overestimate of pure CO 2 density (see Table 1) and the underestimate of gas mixture density by CHEMTOUGH (see Table 1), this code predicts larger pressure increases than any of the other codes.…”

“…Viscosities are reasonably well estimated at high pressures. At low pressures, one code (SIMUSCOPP), which uses the Lohrentz-Bray-Clark viscosity model, estimates a lower viscosity for pure CO 2 than for pure CH 4 . As for solubilities, given as mole fraction of the gas component in the aqueous phase (x l CH4 , x l CO2 ), there is fair agreement at 40 bars.…”

“…The ability to simulate accurately the mixing of supercritical CO 2 and methane (CH 4 ) is essential for modeling reservoir processes under injection by CO 2 . We have undertaken a comparison of reservoir simulators focused on two test problems to compare simulation capabilities applicable to carbon sequestration in oil and gas reservoirs as part of a broader code intercomparison study [1].…”
