Abstract
Corrosion inhibition compositions and methods useful for inhibiting corrosion are provided. The corrosion inhibition compositions comprise at least one filming agent and at least one promoting agent and the methods for inhibiting corrosion on metal surfaces utilize the disclosed corrosion inhibiting compositions.
Claims9
A corrosion inhibition composition configured to treat one or more metal surfaces, the corrosion inhibition composition comprising:
- at least one filming agent comprising 3,5-dimethyl-1-hexyn-3-ol, wherein the corrosion inhibition composition comprises about 11 wt % of the at least one filming agent;
- at least one coupling agent comprising an alkyl imino propionic acid comprising an alkyl indirectly linked to an amine of the alkyl imino propionic acid via an ether spacer;
- at least one promoting agent comprising potassium polysulfide, wherein the corrosion inhibition composition comprises about 1 wt % of the at least one promoting agent;
- and
- at least one solvent.
A method of inhibiting corrosion of metal surfaces, the method comprising:
- contacting at least one metal surface with a corrosion inhibition composition comprising:
- at least one filming agent comprising 3,5-dimethyl-1-hexyn-3-ol, wherein the corrosion inhibition composition comprises about 11 wt. % of the at least one filming agent;
- at least one coupling agent comprising an alkyl imino propionic acid comprising an alkyl indirectly linked to an amine of the alkyl imino propionic acid via an ether spacer;
- at least one promoting agent comprising potassium polysulfide, wherein the corrosion inhibition composition comprises about 1 wt % of the at least one promoting agent;
- and at least one solvent.
A method of treating a subterranean hydrocarbon producing formation with a corrosion inhibiting composition such that corrosive effects of an acidizing composition on metal surfaces in contact therewith are reduced, comprising:
- contacting a subterranean zone with the corrosion inhibiting composition comprising:
- at least one filming agent comprising 3,5-dimethyl-1-hexyn-3-ol, wherein the corrosion inhibition composition comprises about 11 wt. % of the at least one filming agent;
- at least one coupling agent comprising an alkyl imino propionic acid comprising an alkyl indirectly linked to an amine of the alkyl imino propionic acid via an ether spacer;
- at least one promoting agent comprising potassium. polysulfide, wherein the corrosion inhibition composition comprises about 1 wt % of the at least one promoting agent;
- and at least one solvent.
