The droplet was hung on the tip until reaching to the equilibrate state before recording droplet image and then the video was analyzed with the Krüss software according to the Young−Laplace equation. Scheme figure of interfacial tension measurement at high pressures was shown in Figure S1. ...
the insoluble CaCO3 will bee soluble again. You can find this equation easily in chem. book. I hope both of you know what I am taking about and find this information helpful calcium hydroxide + carbon dioxide → calcium carbonate + water Ca(OH)2 + CO2 → CaCO + H2O 当calci...
Based on our previous development of the molecular interaction potential for pure H_2O and CO_2[Zhang,Z.G.,Duan,Z.H.2005a.Isothermal-isobaric molecular dynamics simulations of the PVT properties of water over wide range of temperatures and pressures.Phys. Earth Planet Interiors 149,335-354;Zh...
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...
Based on mass conservation, momentum, and energy balance, the model employs a state-of-the-art equation of state and transport models to analyze the variations of multiphase flow behaviors and CO2 properties in a wellbore. Applied in the scenario of a drilled gas kick, the proposed model is ...

waterA new form of equation of state is proposed for use over extremely wide ranges of pressure where conventional equations fail, In particular, fluids, including H2O and CO2 as well as argon, etc., remain more compressible at very high densities than can be represented by typical equations ...
The variances in the diagonal of the covariance matrix (wherei = j) were excluded because they are always positive and do not contribute to the estimate of spatial coherence. Finally, the spatial coherence of WS anomaly was defined as the following equation: ...
The surface area and microporous volumes werecalculated using the Dubinin–Radushkevitch (D-R) equation basedon CO2adsorption at 273 K. The CHA was synthesized witha lower Si/Al ratio, and the surfaces and microporous volumes werechanged greatly by ion exchange. KFI had a higher Si/Al ratio...
1. Introduction CO2 flooding is considered one of the most effective tertiary recovery processes in light/medium oil reservoirs and has been widely used in petroleum industry. However, the complicated displacement mechanisms involved CO2 injection have n关键词: CO2 flooding, dynamic performance, monitori...
