simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Near-Infrared Study of Water and Water-Benzene Mixtures at High Temperatures and Pressures
Near-infrared absorption of water and water-benzene mixtures has been measured at temperatures and pressures in the range of subcritical and supercritical condition of water. The molar absorption intensity of the OH stretching overtone transition of neat water was obtained. It decreases linearly with increasing pressure in the region of gas and gaslike density. Enthalpy for dimerization has bee...
متن کاملAqueous mixtures to supercritical temperatures and at high pressures
Thermophysical properties of dense supercriiicai water with special emphasis on dielectric permittivity are discussed. Phase diagrams and some critical curves of the binary systems H20—H2, H2O—N, H20—02, H20-CH4 and H20-He to 450 °C and 200 MPa are shown. H20-He tas a type I critical curve. A rational equation of state to calculate phase diagrams and critical curves for polar—non polar systems ...
متن کاملViscosity measurements of alcohol-water mixtures and the structure of water.
In a previous paper,' a model of the hydrogen bond was proposed that gave a structure for water differing markedly from others that have been suggested.2 According to this model, the hydrogen bond would not be located between any two atoms of a given molecular system, as in the case of an ordinary bond, but it would be a collective bond linking a number of molecules together and consisting of a...
متن کاملWater-carbon dioxide mixtures at high temperatures and pressures as studied by infrared and Raman spectroscopies
The state of aggregation of water dissolved in supercritical carbon dioxide has been investigated under isobaric heating (T=40-340°C, P=250 bar) using infrared absorption and Raman scattering spectroscopies. Quantitative analysis of experimental spectra has shown that below 100°C, water exists only in its monomeric form (solitary water surrounded by CO2 molecules) whereas H-bonded species, name...
