Preparation of new stable hydrogen sulfide scavengers useful in both water as well as oil medium applications
The disclosure provides compositions and methods that are useful in removing, lowering, or otherwise controlling hydrogen sulfide and mercaptans. The compositions and methods can be used in any industry where hydrogen sulfide poses problems, such as when dealing with crude oil based, natural gas based, and/or coal based products. In some embodiments, the compositions include one or more alkoxylated amino formaldehyde adducts.
1. A composition comprising at least one hydrogen sulfide scavenger comprising a structure selected from the group consisting of:
wherein each R is independently selected from a hydrogen, methyl, ethyl, propyl, and/or CH 2 OR 10 , where R 10 ═H, methyl, ethyl, propyl, isopropyl, butyl, phenyl, or benzyl; and wherein each R 1 is independently selected from a hydrogen or methyl.
2. The composition of claim 1 , wherein the composition further comprises a stream.
3. The composition of claim 2 , wherein the stream is aqueous, gaseous, organic, or any combination thereof.
4. The composition of claim 1 , wherein the composition is anhydrous.
5. The composition of claim 1 , wherein the composition comprises an aqueous solvent or an organic solvent.
