Abstract
Compositions and methods for use in treating hydrocarbon liquids are provided. Specifically, the compositions and methods of the present disclosure relate to additives including betaine and one or more organic acids. In some embodiments, an additive comprising betaine and an organic acid may be added to a hydrocarbon liquid. In certain embodiments, the additive may be added to a hydrocarbon liquid prior to a processing operation.
Claims16
A method of contaminant removal comprising:
- introducing one or more organic acids and one or more organic acid surfactant boosters into a hydrocarbon liquid, and thereafter introducing the hydrocarbon liquid into a vessel,
- wherein the one or more organic acids and the one or more organic acid surfactant boosters are introduced into the hydrocarbon liquid at an organic acid to organic acid surfactant booster mole ratio of about 0.01:0.5, wherein the one or more organic acid surfactant boosters comprise at least one surfactant selected from the group consisting of a betaine, phosphate ester, a quaternary amine, a polyol, a complex polyol ester, a thiophosphate ester, an alcohol alkoxylate, and any combination thereof;
- wherein the one or more organic acids comprises at least one organic acid selected from the group consisting of acetic acid, citric acid, formic acid, glycolic acid, and any combination thereof;
- and
- separating at least a portion of contaminants from the hydrocarbon liquid in the vessel, wherein at least the one or more organic acids and/or the one or more organic acid surfactant boosters interact with the contaminants in the hydrocarbon liquid, wherein the separating removes amines from the hydrocarbon liquid in an amount of about 50% or more by weight of the hydrocarbon liquid and further removes calcium from the hydrocarbon liquid in an amount of about 30% or more by weight of the hydrocarbon liquid.

A method of contaminant removal comprising:
- introducing one or more organic acids and one or more organic acid surfactant booster into a water feed, wherein the one or more organic acid surfactant boosters comprise at least one surfactant selected from the group consisting of a betaine, phosphate ester, a quaternary amine, a polyol, a complex polyol ester, a thiophosphate ester, an alcohol alkoxylate, and any combination thereof, wherein the one or more organic acids and the one or more organic acid surfactant booster are introduced into the water feed at an organic acid to organic acid surfactant booster mole ratio of about 0.01:0.5;
- combining at least the water feed and crude oil and thereafter introducing the hydrocarbon liquid into a vessel;
- and
- separating salt from the crude oil, wherein the separating salt further removes at least amines and calcium from the crude oil.
