Abstract
A bio-based corrosion inhibitor composition includes a corn stillage product, and may be a substantially water insoluble fraction of corn stillage. The corrosion inhibitor composition is useful in protecting metal articles from corrosion.
Claims10
A corrosion inhibitor composition, comprising an acid solution containing a substantially water insoluble fraction of corn stillage.
A method for inhibiting corrosion of a metal article, said method comprising:
- (a) providing a corrosion inhibitor including a substantially water insoluble fraction of corn stillage;
- and
- (b) contacting the metal article with said corrosion inhibitor.
A method for inhibiting corrosion of a metal article, comprising applying to the metal article an amount of substantially water insoluble liquidous fraction of corn stillage effective to inhibit corrosion of the metal article.
A method for inhibiting corrosion, comprising providing a corrosion inhibitor including a substantially water insoluble liquidous fraction of corn stillage, and interacting said corrosion inhibitor with a corrosive agent having a chloride salt.
An anti-corrosion composition, comprising a chloride salt and an amount of substantially water insoluble liquidous fraction of corn stillage that is effective to reduce corrosion of a metal article.
A method for inhibiting corrosion of a metal article, comprising providing a corrosion inhibitor including a substantially water insoluble liquidous fraction of stillage, and positioning said corrosion inhibitor so as to be contactable with the metal article.
