Development of a novel high temperature stable scavenger for removal of hydrogen sulfide

A method of treating hydrogen sulfide in a stream comprising:

• adding a composition to a stream comprising an amount of hydrogen sulfide, wherein the composition comprises one or more scavenger compounds having the following general formula:
• wherein the C1-C6 ring structure may be aromatic or cyclic aliphatic;
• C1-C6 may be independently selected from carbon, nitrogen, oxygen, and sulfur, wherein C2 may be present or absent and, if absent, the ring structure is a five-membered ring structure;
• wherein C2-C4 may be independently selected from the group:
• X-R-{(OCH2)kOH}m;
• wherein the ring structure may be substituted with an electron withdrawing group or an electron donating group;
• X may be selected from the group consisting of carbon, nitrogen, oxygen, sulfur, a carbonyl group, an alkyl group, and an alkenyl group;
• R may be selected from the group consisting of hydrogen, an alkyl group, an alkenyl group, an alkynyl group, nitrogen and oxygen, wherein the alkyl group, alkenyl group and the alkynyl group may be unsubstituted or substituted;
• k is an integer selected from 0 to 25;
• and
• m is an integer selected from 1 to 4.
