sulfur solubility table

Table 1 shows that in the range T = 25–175 C, the solubility of sulfur in DMSO increases by 100 times, and the concentration of saturated sulfur solutions at T ≈ 25 C increases up to 15 times. For reproduction of material from all other RSC journals. Hino et al. that the correct acknowledgement is given with the reproduced material. Solubility of sulfur in mixed solvents of {toluene (1 − x*) + [C 6 mim][PF 6] (x*)}. The T-dependence of solubility of solids, as a rule, is expressed graphically in the form of solubility curves [ 15 ]. Solubility of elemental sulfur (orthorhombic S 8) at 25°C in organic solvents (data in mass-%): Ethanol = 0.066 Acetone =0.079 Diethyl ether =0.181 (1)) of the system at various temperatures10,11) and compared their results to those reported by other researchers. Res. Therefore, the activity of sulfur was assumed as 0.005 and 0.0025. Please enable JavaScript Reproduced material should be attributed as follows: Information about reproducing material from RSC articles with different licences 9, the sulfur content depends on the activities of aluminum and sulfur, but the observed sulfur content in the 12CaO·7Al2O3 phase in the solid oxide is larger than that in the molten oxide of the sample with identical composition. Because when the mass ratio of this oxide to solid steel is enough large, sulfur can be dissolved in this oxide and the formation of CaS can be suppressed. * Three-parameter temperature-dependent equations for the binary interaction coefficients between sulfur and solvents are proposed. Elemental Sulfur Chemical Reviews, 1976, Vol. 7Al 2 O 3 was independent of the heating temperature and was higher than that in the liquid oxide of the same composition. © 2019 by The Iron and Steel Institute of Japan, [Advance Publication] Released: 2019/06/22. Therefore, the observed sulfur content in this study is reasonable. (2)18) and (3).18) For the Al-killed steel, the activity of oxygen can be calculated using Eq. Chem. 8 and 9 show the ARE and AARE values of sulfur solubility in H 2 S calculated from the experimental data at three different temperatures (316.26, 338.71, and 363.15 K). Fig. Licence. This may take some time to load. fluorine or chlorine), according to the following reactions: If the exchange reaction with sulfide is considered, the following equation can be written: From the mass balance calculations, if all free oxygen sites are replaced by sulfur ions, the sulfur content would increase to 2.28 mass%. It is important to accurately predict the elemental sulfur solubility in hydrogen sulfide, carbon dioxide, and methane because these are the three main components of high-sulfur-content natural gas. The 12CaO·7Al2O3 phase is known to be an electrically conductive oxide ceramic.19,20,21) Its crystal has a unique subnanoporous structure composed of 12 positively charged cages, including two free oxygen ions which maintain electrical neutrality. Table 1. In the case to suppress the formation of CaS, desulfurization is generally conducted in the secondary refining. Sulfur (in British English: sulphur) is a chemical element with the symbol S and atomic number 16. sci-tech@hotmail.com Fetching data from CrossRef. Temperature dependence of the equilibrium sulfur content in the molten oxide. In this calculation, the sulfide capacity at 1823, 1873, and 1923 K, the measured values were used and those at 1723 and 1773 K were estimated using the temperature dependence obtained from the Arrhenius equation. Fundamentals of High Temperature Processes, Solubility of Sulfur in the Solid Oxide of the Calcium-Aluminate System. (2) Sulfur was dissolved only in 12CaO·7Al2O3 at approximately 1.2 mass% while the sulfur content in the other oxides was very low. is available on our Permission Requests page. In this work, we show that the binary interaction coefficients are not constant, but temperature dependent. B.  Fincham and  F. D.  Richardson: E.  Schürmann,  R.  Bruder,  K.  Nürnberg and  H.  Richter: S.  Ban-ya,  M.  Hobo,  T.  Kaji,  T.  Itoh and  M.  Hino: Steelmaking Data Sourcebook, ed. Sulfur solubility in pure and mixed organic solvents Steven F. Sciamanna and Scott Lynn Cite this: Ind. If the ratio of the partial pressure of O2 and S2 is fixed, the sulfur content in the oxide can be calculated using Eqs. The binary interaction coefficients between sulfur and hydrogen sulfide, carbon dioxide, and methane are the key parameters for predicting the sulfur solubility with a thermodynamic model. Licence. Based on Table 5, the total ARE and AARE values for predicting the sulfur solubility were 6.30% and 7.90%, respectively. This work was performed under the Research Program “Dynamic Alliance for Open Innovation Bridging Human, Environment and Materials”. The sulfur content in the CaS-saturated CaO–Al2O3 system was measured and the results can be summarized as follows: (1) In the Al2O3-rich oxide, CaO·Al2O3, 12CaO·7Al2O3, and CaS phases were observed, whereas the dominant phases in the CaO-rich oxide were 12CaO·7Al2O3, 3CaO·Al2O3, and CaS. Material from this article can be used in other publications provided by The 19th Committee on Steelmaking, The Japan Society for the Promotion of the Science, Gordon and Breach, New York, (1988), 203. Assuming that the activity of aluminum is 0.05 or 0.025 and that of sulfur is 0.005 or 0.0025, the equilibrium sulfur content in the molten oxide was calculated and the results shown in Fig. School of Petroleum Engineering, Southwest Petroleum University, Chengdu 610500, China During development of high sulfur-content natural gas fields, gaseous sulfur is likely to precipitate and deposit in the reservoir and transmission pipelines owing to changes in the temperature, pressure, and gas components.
