TL;DR: In this paper, the solubility of methane was measured in brines at temperatures from 0 to 300/sup 0/C by the technique of gas extraction, expressed in terms of the Henry's law constant, were fit to a smoothing and interpolation formula for subsequent interpretation and analysis.
Abstract: The solubility of methane was measured in brines at temperatures from 0 to 300/sup 0/C by the technique of gas extraction. Results, expressed in terms of the Henry's law constant, were fit to a smoothing and interpolation formula for subsequent interpretation and analysis. The results can be extrapolated to temperatures above 300/sup 0/C. The Henry's law constant exhibits maximums in the temperature range 80 to 100/sup 0/C. Methane is salted out with increased concentration of dissolved salts. The salting-out coefficient is strongly dependent upon temperature. The effect of temperature on solubility in a hypersaline geothermal brine is different from that for the simpler sodium chloride brines owing to the more complex chemistry of the geothermal brine.

TL;DR: The contrary behavior of lithium in these two brines shows that, in systems where it has behaved conservatively, lithium isotopes can distinguish brines derived from marine sources.
Abstract: Hypersaline calcium/chloride shield brines are ubiquitous in Canada and areas of northern Europe. The major questions relating to these fluids are the origin of the solutes and the concentration mechanism that led to their extreme salinity. Many chemical and isotopic tracers are used to solve these questions. For example, lithium isotope systematics have been used recently to support a marine origin for the Yellowknife shield brine (Northwest Territories). While having important chemical similarities to the Yellowknife brine, shield brines from the Sudbury/Elliot Lake (Ontario) and Thompson/Snow Lake (Manitoba) regions, which are the focus of this study, exhibit contrasting lithium behavior. Brine from the Sudbury Victor mine has lithium concentrations that closely follow the sea water lithium-bromine concentration trajectory, as well as δ6Li values of approximately—28 %o. This indicates that the lithium in this brine is predominantly marine in origin with a relatively minor component of crustal lithium leached from the host rocks. In contrast, the Thompson/Snow Lake brine has anomalously low lithium concentrations, indicating that it has largely been removed from solution by alteration minerals. Furthermore, brine and nonbrine mine waters at the Thompson mine have large δ6Li variations of ∼30 %o, which primarily reflects mixing between deep brine with δ6Li of—35 ± 2‰ and near surface mine water that has derived higher δ6Li values through interactions with their host rocks. The contrary behavior of lithium in these two brines shows that, in systems where it has behaved conservatively, lithium isotopes can distinguish brines derived from marine sources.

TL;DR: In this article, inorganic salts are removed from an unpotable water stream, which contains suspended living microorganisms and their debris products, particularly seawater or agricultural field drainage water.
Abstract: Inorganic salts are removed from an unpotable water stream, which contains suspended living microorganisms and their debris products, particularly seawater or agricultural field drainage water. Chemicals such as caustic soda and/or chlorine, and derivatives therefrom, sterilize the water and remove from it certain dissolved and suspended constituents. From the sterilized water is separated a more concentrated stream of waste brine containing debris and other suspended materials, and most of the dissolved sodium chloride. From the remaining portion of the water is separated a more concentrated stream of sodium chloride, which is electrolized to provide a source of caustic soda, chlorine, and derivatives therefrom; the less concentrated portion is recovered as a source of potable water.

TL;DR: In this paper, the role of individual ions and salinity in low salinity effect in enhanced oil recovery (EOR) through direct measurements of oil/brine/rock interfacial behaviors, oil displacement efficiencies, and oil-water relative permeability in sandstone porous media.
Abstract: The low salinity effect (LSE) in enhanced oil recovery (EOR) is widely accepted. However, its underlying mechanisms remain unclear due in part to the complex interactions at the oil/brine/rock interface. The chemistry of brine largely depends on the ionic composition. Thus, in this work, attention was placed on the roles of individual ions and salinity in LSE through direct measurements of oil/brine/rock interfacial behaviors, oil displacement efficiencies, and oil–water relative permeability in sandstone porous media. The results showed that the oil/water interfacial tensions (IFTs) were weakly dependent on ion and the lowest IFTs were generated at the salinities of 0.2–0.5 wt %. In contrast, the interfacial dilational modulus varied significantly with ion types and salinities due to the adsorption of polar components at the oil/water interface. Moreover, wettability alteration of the sandstone surface was found to be associated with the divalent ions in our work. As a result of the viscoelastic interfac...
