Beschreibung
Zusammenfassung:	Functionalized alpha-hydroxy alkyl ethers have been found to perform as non (or anti-) scaling hydrogen sulfide scavengers. A method of scavenging hydrogen sulfide includes contacting a fluid containing hydrogen sulfide with a treatment fluid including a functionalized alpha-hydroxy alkyl ether. Accordingly, the alpha-hydroxy alkyl ether reacts with the hydrogen sulfide to reduce the amount of hydrogen sulfide in the fluid. The functionalized alpha-hydroxy alkyl ether is functionalized with a phosphate group, phosphonate group, sulfate group, or sulfonate group. A broad range of alpha-hydroxy alkyl ethers are disclosed. L'invention concerne des a-hydroxy-alkyléthers fonctionnalisés utilisés en tant que fixateurs de sulfure d'hydrogène de non entartrage ou antitartre. Un procédé de fixation de sulfure d'hydrogène inclut la mise en contact d'un fluide contenant du sulfure d'hydrogène avec un fluide de traitement incluant un a-hydroxy-alkyléther fonctionnalisé. Par conséquent, l'a-hydroxy-alkyléther réagit avec le sulfure d'hydrogène pour réduire la quantité de sulfure d'hydrogène dans le fluide. L'a-hydroxy-alkyléther fonctionnalisé est fonctionnalisé avec un groupe phosphate, un groupe phosphonate, un group sulfate ou un groupe sulfonate. Une large gamme d'a-hydroxy-alkyléthers est divulguée.
