CO2solubility in water can also be estimated by thermodynamic modeling, which is more cost-effective than experimental measurements. In recent years, the potential of theoretical models to effectively represent influential characteristics such as pressure, temperature, and electrolyte concentrations has attrac...
The molar Gibbs free energy difference was expressed by the logarithm of the ratio of the concentration of CO2 dissolved in water at the hydrate surface to the solubility of CO2 in the aqueous solution in equilibrium with the hydrate. The dissociation rate constant was determined from the ...
CO 2 that is injected into a geological storage reservoir can leak in dissolved form because of brine displacement from the reservoir, which is caused by l... Ahmad,Nawaz,W?rman,... - 《Advances in Water Resources》 被引量: 0发表: 2016年 UPSTREAM-DOWNSTREAM INTEGRATED PROCESS FOR THE UPGR...
In recent years, some surfactants that can be dissolved in CO2 are investigated to stabilize foam(Chen et al., 2014; Ren et al., 2014; Zhang et al., 2020), since they can simplify the foam flooding process without extra water injection and these surfactants could transport fast with CO2-...
Amine-surfactant can be converted to be cationic surfactant in water solution saturated with CO2, which can enhance their foaming ability and foam stability, and the foaming ability can be switched off or on by CO2 or replacing with N2 with heating, so the amine-surfactants have great potential...
WaterON 21 August 1986, a massive release of carbon dioxide from Lake Nyos in Cameroon killed about 1,700 people. A similar event occurred on 15 August 1984 at Lake Monoun, also in Cameroon. It was suggested(1-5) that the CO2 released was initially dissolved in the hypolimnion (dense ...
The viscosity of aqueous NaCl solutions with dissolved CO2 was measured at conditions representing an underground aquifer at a depth of (1000 to 2000) m for the geological storage of CO2 (i.e., (30 to 60) °C and (10 to 20) MPa at a mass fraction of NaCl between 0 and 0.03 by us...
The changes in pH do not follow the observed changes in biomass, suggesting species specific responses to changes in pH and dissolved inorganic carbon availability. In our study, a CO2 enriched atmosphere led to an increase in inorganic carbon in the control media flasks, while alkalinity was ...
Moreover, owing to their high viscosity and corrosiveness, the absorbents are typically dissolved in water and used as aqueous solutions, which lowers their performance. In contrast, in the physical absorption method, the gas solubility increases as the temperature decreases and pressure increases, ...
(21 g, 375 mmol) dissolved in water (30 mL) was prepared and cooled to 25 °C before it was added to the above reaction mixture. Subsequently, 80 mL ammonium hydroxide (25%) was added slowly to yield a yellowish-green solid precipitation. Finally, the mixture was stirred ...
