Vapour pressure and excess Gibbs free energy of binary mixtures of hydrogen sulphide with ethane, propane, and n-butane at temperature of 182.33K

Addition of the Hydrogen Sulfide Group to the PPR78 Model (Predictive 1978, Peng–Robinson Equation of State with Temperature Dependent kij Calculated through a Group Contribution Method)

“…Table presents the list of pure components used in this study. Their physical properties ( T c , P c , and ω) originate from Poling et al Table details the sources of the binary experimental data used in our evaluations – along with the temperature, pressure, and composition range for each binary system. Most of the data available in the open literature (2299 bubble points + 1561 dew points + 63 mixture critical points) have been collected.…”

Phase Equilibria of H2S-Hydrocarbons (Propane, n-Butane, and n-Pentane) Binary Systems at Low Temperatures

“…It is not surprising as for these temperatures the pressure is quasiconstant for an important range of composition. If these points are removed along with the data set of Lobo et al, the relative deviation is reduced to a similar order of magnitude than the two other systems (Figure ).…”

“…Relative deviations for the system H 2 S– n -butane (enlargement between (0 and 2) MPa). Experimental data are taken from □, Lobo et al; △, Leu and Robinson;, and ×, this work.…”

“…Although the open literature is rich about the carbon dioxide + hydrocarbons mixtures, the data in the presence of hydrogen sulfide are rarer due to the toxic nature of it. As mentioned by Lobo et al, most of the experimental results available about H 2 S and lighter alkanes come from the years 1940 to 1960. Table shows the available studies about hydrogen sulfur and lighter alkanes.…”
