Solubility and Thermodynamic Parameters of H₂S/CH₄ in Ionic Liquids Determined by ¹H NMR.

ABSTRACT: Natural gas remains an important global source of energy. Usually, sour gas from the well or refinery stream contains H₂S among other contaminants that should be removed to fulfill permissible standards of use. Despite the use of different gas-liquid sour gas upgrading technologies, ionic liquids (ILs) have been recognized as promising materials to remove H₂S from sour gas. However, data concerned with thermodynamic solution functions of H₂S in ILs have scarcely been reported in the literature. In this work, solution ¹H NMR spectroscopy was employed for quantifying H₂S soluble in [BMIM][Cl] and for gaining a better understanding of the H₂S-IL interaction. Experiments were carried out in a Young-Tap NMR tube containing a satu
