Abstract:
Certain functionalized aldehydes scavengers may be used to at least partially scavenge sulfur-containing contaminants from fluid systems containing hydrocarbons and/or water. The contaminants scavenged or otherwise removed include, but are not necessarily limited to, H 2 S, mercaptans, and/or sulfides. Suitable scavengers include, but are not necessarily limited to, reaction products of glycolaldehyde with aldehydes; reaction products of glycolaldehyde with a nitrogen-containing reactant (e.g. an amine, a triazine, an imine, an aminal, and/or polyamines); non-nitrogen-containing reaction products of a hydrated aldehyde with certain second aldehydes; reaction products of 1,3,5-trioxane with hydroxyl-rich compounds (e.g. glyoxal, polyethylene glycol, polypropylene glycol, pentaerythritol, and/or sugars); and reaction products of certain aldehydes with certain phenols; and combinations of these reaction products.

Claim (Index 11):
A method for at least partially scavenging a sulfur-containing contaminant from a fluid system selected from the group consisting of hydrogen sulfide, mercaptans, sulfides (salts of H 2 S), and mixtures thereof, the method comprising:\n contacting the fluid system with a scavenger in an amount of is a mole ratio of scavenger to sulfur-containing contaminant of 0.1:1 to 3.0:1 to at least partially scavenge the sulfur-containing contaminant from the fluid system, where the scavenger is selected from the group consisting of:\n reaction products of glycolaldehyde with aldehydes, formaldehyde acetals, or formaldehyde hemiacetals; \n reaction products of glycolaldehyde with a nitrogen-containing reactant; \n non-nitrogen-containing reaction products of a hydrated aldehyde with a second aldehyde; \n reaction products of 1,3,5-trioxane with a hydroxyl-rich compound; \n reaction products of an aldehyde with a phenol; and \n combinations thereof; and \n at least partially scavenging the sulfur-containing contaminant from the fluid system.
