    Solubility is the property of a solid, liquid or gaseous chemical substance called solute to dissolve in a solid, liquid or gaseous solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature, pressure and presence of other chemicals (including changes to the pH) of the solution. 1 A COMPARISON OF PHYSICAL SOLVENTS FOR ACID GAS REMOVAL INTRODUCTION Physical solvents such as DEPG (Selexol™ or Coastal AGR®), NMP or N-Methyl Pyrrolidone (Purisol®), Methanol (Rectisol®), Propylene Carbonate (Fluor Solvent™), and others are becoming increasingly popular as gas treating solvents, especially for coal gasification Size: KB.

    These coefficients, combined with experimental data for the vapor pressure of methanol, Henry's constants, partial molar volumes, and Margules coefficients for dissolved gases in methanol, yield a correlation for calculating solvent losses as a function of temperature, pressure, and gas composition. (EG), diethylene glycol (DEG), triethylene glycol (TEG) and methanol are commonly used in wet gas dehydration processes. EG and methanol are also injected into wet gas to act as hydrate inhibitors. Acid gas removal can be accomplished by the physical solvent DEPG, which is a mixture of dimethyl ethers of polyethylene glycols, and by methanol.

Oxygen, nitrogen and hydrogen have been at the core of .   The solubility of gases is not constant in all conditions. If temperatures differ, the solubility of gases differ. Figure \(\PageIndex{1}\): The solubilities of these gases in water decrease as the temperature increases. All solubilities were measured with a constant pressure of kPa (1 atm) of gas above the solutions. (CC BY; OpenStax).

Polar liquids are best suited for these processes because they have a high degree of selectivity be- tween acid gases and the valuable gas components. Methanol serves as the solvent in Lurgi's proprietary Rectisol process. For example, methanol has been effectively used to remove water (and acid gases such as carbon dioxide and hydrogen sulfide) from natural gas [1] prior to its subsequent liquefaction.

It was found that the solubilities of gases in multicomponent systems deviate from the values estimated from binary data.

The solubility of inert gases in methanol for multi component systems is much greater than that in a binary system due to the influence of carbon dioxide and carbonyl by: The solubilities of methanol, toluene, acetone, n-heptane or n-nonane in nitrogen, methane or carbon dioxide are determined at temperatures of K.
