A review on the solid–liquid–vapor phase equilibria of acid gases in methane

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