Patent ID: 7288234

Claim:
A method for scavenging hydrogen sulfide and/or mercaptans from a liquid or gaseous stream which comprises bringing the stream into contact with a scavenging effective amount of at least one scavenger selected from the group consisting of: (i.) a 1,3,5-trisalkanylamino hexahydro-1,3,5-triazine derivative of the formula: wherein each A is independently selected from the formula —(CHR 7 ) x wherein x is from 1 to about 6 and each R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 7 is independently selected from —H or a C 1 -C 6 alkyl; (ii.) a nitrogen heterocyclic compound of the formula: e wherein Y is —N or —O and R 8 is 2-aminoethyl or 2-hydroxyethyl; and (iii.) an amine oxide of the formula (RCONHCH 2 CH 2 CH 2 )(CH 3 ) 2 N→O wherein R is a radical selected from the group consisting of decyl, cocoyl, lauryl, cetyl and oleyl and thereby scavenging hydrogen sulfide and/or mercaptan from the liquid or gaseous stream.
