Abstract
The present disclosure provides compositions and methods for reducing sulfur-containing compounds in a hydrocarbon fluid. The compositions include an alpha amino ether and a synergistic compound. Additionally, the compositions may include a third component. The third component may be, for example, a heteroatom-containing component or a solvent.
Claims20
A method for reducing an amount of a sulfur-containing compound present in a hydrocarbon fluid, comprising:
- adding an effective amount of a composition to the hydrocarbon fluid,
- wherein the composition comprises a sulfide scavenger and a synergistic compound,
- wherein the sulfide scavenger comprises an alpha amino ether, and
- wherein the synergistic compound comprises Formula (I):
- wherein n is 1 or 2,
- X is NR5, O, or S,
- Y is H, OH, SH, NH2, NHR, NHCOR, SR, or OR,
- Z is H, OH, SH, NH2, NHR, NHCOR, SR, or OR,
- R is H or a C1-C10 alkyl or alkenyl group,
- R1 and R2 are each independently H, a C1-C10 alkyl or alkenyl group, a cyclic group, a carbocyclic group, or a heterocyclic group,
- R3 and R4 are each independently H or a C1-C10 alkyl or alkenyl group, and
- R5 is H or a C1-C10 alkyl group, provided that the synergistic compound excludes diethanolamine.
A method for reducing an amount of a sulfur-containing compound present in a hydrocarbon fluid, comprising:
- adding an effective amount of a composition to the hydrocarbon fluid,
- wherein the composition comprises a sulfide scavenger and a synergistic compound,
- wherein the sulfide scavenger comprises an alpha amino ether, and
- wherein the synergistic compound comprises diisopropanolamine.
