“…The amount adsorbed was determined by mass balances applied to the gaseous phase using pressure-volume-temperature (PVT) measurements and the ideal gas equation, as reported by Talu (1998) and Llewellyn and Maurin (2007). For pressures above 1 bar, the compressibility factor was incorporated into the mass balance equations and estimated by Bender's equation of state for pure fluids (Ghazouani et al, 2005).…”

-Separation of CO 2 from CO 2 -CH 4 mixtures is an important issue in natural gas and biogas purification. The design of such separation processes depends on the knowledge of the behavior of multicomponent adsorption, particularly that of CO 2 -CH 4 mixtures. In this study, we present a series of experimental binary equilibrium isotherms for CO 2 -CH 4 mixtures on an activated carbon at 293 K and compare them with predicted values using the Ideal Adsorption Solution Theory (IAST) and the Extended Langmuir (EL) model. Even at concentrations of ca. 20% for all binary isotherms, CO 2 already presents higher adsorbed amounts with respect to CH 4 . A maximum selectivity of around 8.7 was observed for a nearly equimolar mixture at 0.1 MPa. The IAST in conjunction with the Toth equation showed slightly better results than IAST using the Langmuir equation and both showed better results than the EL model.

“…All monobranched alkanes, in the five-to eight-carbon atom range are found to exhibit inflection behavior (14,(27)(28)(29)(30). Interestingly, n-hexane also shows a slight inflection at a loading of four molecules per unit [see, e.g., Fig.…”

“…There are several pristine works that explain this phenomenon in detail [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Adsorbents are porous solids, preferably having a large surface area per unit mass.…”

Pressure swing adsorption (PSA) is a well-established gas separation technique in air separation, gas drying, and hydrogen purification separation. Recently, PSA technology has been applied in other areas like methane purification from natural and biogas and has a tremendous potential to expand its utilization. It is known that the adsorbent material employed in a PSA process is extremely important in defining its properties, but it has also been demonstrated that process engineering can improve the performance of PSA units significantly. This paper aims to provide an overview of the fundamentals of PSA process while focusing specifically on different innovative engineering approaches that contributed to continuous improvement of PSA performance.
