“…The phase diagrams of the three measured systems calculated by the PR-EoS and other three systems comparing calculations against literature data [22] are shown in the Figure 1. According to Scott and van Konynenburg, the phase diagram of this system is classified as type III [7]. This means that the curves presented in the phase envelops of Figure 1 are dew lines, therefore no density was measured in the liquid region.…”

“…BIPs for the CH 4 -H 2 S system have been regressed for both the SAFT-VR Mie EoS (k ij =0.0314) and the PR EoS (k ij =0.0807) models using VLE data from the literature [7] [8] Figure 6, as an example of the modelling result of this system at high pressure (up to 70MPa).…”

“…Despite hydrogen sulphide is a polar molecule, we have considered H 2 S as a non-associating compound due to the good results that classical cubic models have shown to model the phase equilibrium of the CH 4 + H 2 S system [7]. The critical properties (T c and P c ) and acentric factors (ω) of methane and hydrogen sulphide are given in Table 3.…”

“…Thus, the binary parameters avoid wrong predictions of the two phase region during density calculations. A temperature independent k ij has been regressed by minimizing the objective function given in Equation 6, which is based on calculated bubble point pressures and experimental VLE data from the literature [7] [8] [22]. The regressed BIP is reported in Table 5.…”

“…The sweetening and desulphurisation of acid gases, such as the SPREX process [6] or physical and chemical absorption with solvents, are costly processes that require accurate thermodynamic models to design natural gas processing plants. The methane-H 2 S binary system is of interest to the oil and gas industry [7] because CH 4 and H 2 S are important components of reservoir fluids.…”

An accurate description of the phase behavior of the CH 4 1 H 2 S system is given for temperatures from 70 K to the critical temperature of H 2 S and pressures up to 250 MPa. The study includes the solid phases of CH 4 and H 2 S. A global pressure-temperature diagram is presented. The types of temperature-composition and pressure-composition phase diagrams that can be encountered in the studied temperature and pressure ranges have been described. The temperature and pressure ranges where the phase behavior of the system changes have been identified and a representative phase diagram is presented for each range. Phase diagrams have been obtained through the solid-liquid-vapor equation of state proposed by Yokozeki.

In spite of the increasing levels of greenhouse gases in the atmosphere, and their impact on the environment, the demand for natural/biogas will increase significantly in the coming few decades. To cover this demand, the global energy industry is continuously exploiting sour gas reserves located around the world. Nonetheless, sour gas has to be sweetened before the practical utilization of natural or biogas. The cryogenic separation technologies have emerged as a new technology to separate carbon dioxide (CO2) and hydrogen sulfide (H2S gases) from natural/biogas. The cryogenic separation produces less harmful gases, and can be less expensive to operate and maintain in comparison to the conventional technologies. To design cryogenic separation equipment, vapor–liquid equilibrium (VLE), solid–liquid equilibrium (SLE), solid–vapor equilibrium (SVE), and solid–liquid–vapor equilibrium (SLVE) data for the corresponding binary systems (of CH4‐CO2, CH4‐H2S, and H2S‐CO2) and ternary system (of CH4‐H2S‐CO2) are required. The main target of this article is to review the SLVE data for the acid gases (CO2 and H2S) in methane (CH4) as the main constituent of natural/biogas. It will address SLVE data for the binary systems of CH4‐CO2, CH4‐H2S and H2S‐CO2 as well as the ternary system of CH4‐H2S‐CO2. It will not only address the available laboratory data, but it will also discuss, compare and evaluate the different models used to correlate/predict these data. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.
