Solubility of hydrogen sulfide in pure water and in NaCl solutions, from 20 to 320°C and at saturation pressures

Modeling Studies on the Transport of Benzene and H2S in CO2-Water Systems

“…Experimental data in a similar temperature range were also presented by Drummond (1981), falling within 7-10% of the data from Suleimenov and Krupp (1994). Suleimenov and Krupp (1994) Chapoy et al (2005) reported a set of data measured at low temperature and pressure conditions (T<70°C, P<40 bar). The comparison of measured data and calculated values at 35°C, 45°C, 55°C, and 65°C ( Figure A19 and A20) shows that TMVOC_REACT is capable of reproducing measured data at low temperatures and pressures.…”

“…Because (1) the capability of equations of state to reproduce measured data has been proved by Morris and Byers (1991), (2) the same equations of state are used in TMVOC_REACT, and (3) the interaction parameter in TMVOC_REACT is very close to that reported by Morris and Byers (1991), testing against experimental data for this system was not deemed necessary. (Bierlein and Kay, 1953) Table A6 compares H 2 S solubilities measured by Suleimenov and Krupp (1994) with values computed using TMVOC_REACT, showing good agreement except for one large deviation (at 40.4°C and 2.64 bar) attributed either to a transcript or experimental error. Experimental data in a similar temperature range were also presented by Drummond (1981), falling within 7-10% of the data from Suleimenov and Krupp (1994).…”

“…The solubilities measured by Chapoy et al (2005) are mainly for low temperatures and pressures, whereas those measured by Suleimenov and Krupp (1994) cover a larger temperature and pressure range. TMVOC_REACT was also tested against measured data at relatively low temperature (about 50-100°C) but rather high pressure-thus conditions more relevant for CO 2 geological sequestration.…”
