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 20):
The treated fluid system of  claim 12  where for the reaction products of an aldehyde with a phenol:\n the aldehyde is selected from the group consisting of formaldehyde, formaldehyde acetals, formaldehyde hemiacetals, paraformaldehyde, 1,3,5-trioxane, glycolaldehyde, glyoxal, and mixtures thereof; and \n the phenol is selected from the group consisting of phenol, catechol, resorcinol, mono-alkyl group substituted phenol where the alkyl group has from 1 to 12 carbon atoms.
