Solubility and Thermodynamic Parameters of HS/CH in Ionic Liquids Determined by H NMR.

Natural gas remains an important global source of energy. Usually, sour gas from the well or refinery stream contains HS 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 HS from sour gas.
