Carbon capture and storage (CCS) is vital to climate change mitigation, has application across the economy, in addition facilitating atmospheric carbon dioxide removal resulting emissions offsets net negative emissions. This contribution reviews state-of-the-art identifies key challenges which must be overcome order pave way for its large-scale deployment.

We report measurements of the diffusion coefficients CO2 and N2 in pure water at temperatures between (298.15 423.15) K pressures (15 45) MPa. The were made by Taylor dispersion method have a standard relative uncertainty 2.3 %. results found to be essentially independent pressure over range investigated simple relation, based on Stokes–Einstein equation, is proposed correlate experimental data. Some difficulties arising measurement diffusivities slightly soluble acid-gas solutes such as are...
Interfacial tension measurements are reported for the (H2O + CO2) system at pressures of (1 to 60) MPa and temperatures (298 374) K. The pendant drop method was implemented using a high-pressure apparatus consisting view cell, fitted with capillary tube creating H2O drops in CO2 bulk phase. results have relative standard deviation most cases less than 1.0 % good agreement literature values low pressures. However, higher (up 45 MPa), there is significant scatter published data; reasons this...
To understand the strong viscoelastic response showed by aqueous solutions of erucylbis(hydroxyethyl)methylammonium chloride (EHAC) in presence potassium (KCl), steady-state rheology, small-angle neutron scattering (SANS), and cryogenic transmission electron microscopy (cryo-TEM) experiments were performed. This cationic surfactant has ability to self-assemble into giant wormlike micelles. The effect concentration, added salt, temperature investigated. have a gellike behavior at room become...
Raman spectroscopy has been used to follow the hydration of one principal components Ordinary Portland Cement (OPC) clinkers, tricalcium aluminate, both in absence and presence calcium sulfate. Direct in-situ analysis hydrating paste surface was possible. Spectra were recorded regularly during first 24 hours hydration, then systematically after periods up 28 days. X-Ray diffraction performed confirm sample identity, firstly coordination with analysis. Hydration sulfate rapid led initial...
We report the interfacial tension between carbon dioxide and aqueous solutions of mixed salt system (0.864 NaCl + 0.136 KCl) with total molalities (0.98 4.95) mol·kg–1. The measurements were made at temperatures (298 473) K various pressures up to 50 MPa by means imaging a pendant drop CO2-saturated brine surrounded water-saturated CO2 phase. expanded uncertainties 95 % confidence are 0.05 in temperature, 70 kPa pressure, for γ, larger 0.016γ 0.6 mN·m–1. results study indicate that increases...

Abstract The absorption spectrum of diatomic argon in the 780–1080 Å region has been re-analysed using Rydberg-Klein-Rees method. results this study together with an analysis equilibrium and transport properties gaseous have used to establish a potential energy function which is consistent all available data. dissociation dimer estimated at some 7 per cent greater than that indicated previous analyses spectroscopic
We investigated the cluster-size distribution of residual nonwetting phase in a sintered glass-bead porous medium at two-phase flow conditions, by means micro-computed-tomography (μCT) imaging with pore-scale resolution. Cluster-size functions and cluster volumes were obtained image analysis for range injected pore under both imbibition drainage conditions; field view was larger than porosity-based representative elementary volume (REV). did not attempt to make definition REV but used...
