Abstract
Alpha-hydroxy alkyl esters have been found to perform as hydrogen sulfide scavengers. A method of scavenging hydrogen sulfide includes contacting a fluid containing hydrogen sulfide with a treatment fluid including an alpha-hydroxy alkyl ester. Accordingly, the alpha-hydroxy alkyl ester reacts with the hydrogen sulfide to reduce the amount of hydrogen sulfide in the fluid. A broad range of alpha-hydroxy alkyl esters are disclosed.
