Abstract: 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.
