| description | The present invention relates to an aqueous alkanolamine solution demonstrating low volatility comprising 2-dimethylamino-2-hydroxymethyl-1, 3-propanediol useful for removing acid gases from gaseous mixtures. Said aqueous alkanolamine solution may further comprise one or more of an acid or acid-forming compound, another amino compound, an activator, a physical solvent, or one or more other compounds used in gal-liquid treatment practices. Further, the present invention relates to a process for removing acid gases from a gaseous mixture, preferably hydrogen sulfide, comprising the step of contacting the gaseous mixture with said aqueous alkanolamine solution. Examples of the gaseous mixtures include natural gas, synthesis gas, tail gas, and refinery gas.
L'invention concerne une solution d'aminoalcool aqueuse démontrant une faible volatilité comprenant du 2-diméthylamino-2-hydroxyméthyl-1,3-propanediol utile pour éliminer des gaz acides de mélanges gazeux. Ladite solution d'aminoalcool aqueuse peut en outre comprendre un ou plusieurs éléments parmi un acide ou un composé formant un acide, un autre composé amino, un activateur, un solvant physique, ou un ou plusieurs autres composés utilisés dans des pratiques de traitement gaz-liquide. En outre, l'invention concerne un procédé d'élimination des gaz acides à partir d'un mélange gazeux, de préférence du sulfure d'hydrogène, comprenant l'étape consistant à mettre en contact le mélange gazeux avec ladite solution d'aminoalcool aqueuse. Des exemples des mélanges gazeux comprennent le gaz naturel, un gaz de synthèse, un gaz résiduaire et un gaz de raffinerie. |
