aRaman spectrum of the gas phase in the gas-rich fluid inclusions shows sharp peaks typical of the gas mixture: CH4(2911 cm−1), H2S (2602 cm−1), CO2Fermi diad (1281 cm−1, 1384 cm−1), and N2(2326 cm−1), representing symmetric stretching vibrations (ν1) of...
Paclitaxel was dissolved in a solution made up of 50 % Cremophor EL and 50 % absolute ethanol to a concentration of 6 mg/ml (stored at −20 °C, for a maximum of 14 days) and then diluted in normal saline (NaCl 0.9 %) to a final concentration of 0.2 mg/ml just before ...
1), dissolved in water (H2O) film (Eq. 2), and dissociated in an adsorbed state (Eq. 3); (2) oxidation step. The adsorbed H2S reacts with oxygen (O2) to form ending products of elemental sulfur (S0; Eq. 4), sulfur dioxide (SO2; Eq. 5), and sulfate (\({\text{SO}}_{4}...
If Pb[CH3COO]2 and Na2S are mixed and dissolved in water and the solution is filtered then the filterate will give test of View Solution Give balanced equation for the conversions A and B . Sulphide APb(CH3COO)2soln.−−−−−−−−−−−−→ Black precipitate Vi...
To properly address the H2S transport in geological formations, the dissolved amount of H2S in formation waters has to be estimated. To calculate phase equilibrium of H2S + brine systems, actually most of the available basin or reservoir modeling tools use empirical correlations (e.g. Barta and...
The DLS measurement was consistent with ζ-potential measurements indicating AgNPs became less negative in RPMI at pH 7, compared to DI water (Table 2). The change in ζ-potential probably arises due to the screening effect of salts in cell culture medium on the surface charge of ...
metallic materials to cracking in H2S service include H2S partial pressure, in situ pH, the concentration of dissolved chloride or other halide, the presence of elemental sulfur or other oxidant, temperature, galvanic effects, mechanical stress and time of exposure to contact with a liquid water ...
In this model the same equations, based on an equation of state, are used for both the liquid and vapour phase. The model can be extrapolated and the speciation of the components occurring in the liquid phase can be calculated. Moreover the solubility of physically dissolved hydrocarbons (i....
The effect of pH is important because if the pH is either neutral or basic for high water cut systems, the hydrogen sulphide starts dissociating into HS− and S2− ions that remain dissolved in the water, and will not partition into oil and gas. However, presence of ionic salt in ...
Thus, considering that there are molecules of water and oxygen in the gaseous stream treated, H2S could be transformed into SO2 and SO3 according to equations (3), (4). Additionally, this both sulphur oxides could be formed from chemical oxidation of S0 in line with equation (5), (6)....
