A method of measuring the flow of polar corrosion inhibitor comprising:
- providing a polar corrosion inhibitor;
- measuring the corrosion inhibitor with a magnetic flow meter at or before an outlet;
- and
- adding the measured corrosion inhibitor to a non-aqueous, non-conducting liquid from the outlet.
A method of inhibiting corrosion:
- providing a polar corrosion inhibitor;
- adding the polar corrosion inhibitor to a non-aqueous, non-conducting liquid to produce a corrosion inhibited mixture;
- and
- measuring the flow of the corrosion inhibited mixture with a magnetic flow meter.
A method of buffering the pHe of an ethanol composition comprising:
- providing a polar corrosion inhibitor;
- adding the polar corrosion inhibitor to the ethanol composition;
- and
- buffering the ethanol composition to a desired pHe
A polar corrosion inhibitor comprising:
- an amount of a polar compound to provide a conductivity of greater than 5 microSiemens per centimeter;
- an effective amount of an aromatic solvent;
- an effective amount of an aliphatic acid anhydride;
- and
- an effective amount of an amine.
