Definitions
- the present invention relates to the inhibition of corrosion of a metal surface using one or more anti-corrosion agents.
- Corrosion has been the subject of scientific study for more than 150 years. Corrosion is a naturally occurring phenomenon that relates to the deterioration of a material or its properties because of a reaction with its environment. In addition to reduced longevity, corrosion also produces oxides that can further deteriorate a system by erosion, plugging, and fouling. Oxides can deposit on heat transfer surfaces, reducing efficiency, and increasing energy costs. Common sources of corrosion include dissolved oxygen, bacteria, electrolysis (stray current), differential metal (dielectric), and differential cells. Flow, temperature, and pressure can effect the corrosion rate.
- Corrosion inhibitors are used in oil and gas exploration and production, petroleum refining, chemical manufacturing, heavy manufacturing, water treatment, and the product additive industries. As products and manufacturing processes have become more complex and the consequences of corrosion more costly, greater attention is being given to the control and prevention of corrosion. Thus, there is a continued need to identify more effective corrosion inhibitors that minimize financial and environmental costs with better toxicological profiles.
- a feature of the present invention is to inhibit corrosion of a metal surface.
- Another feature of this invention is to provide methods of using an anti-corrosion agent having low toxicity and/or high efficacy to prevent or minimize the corrosion of metal surfaces.

- Metal corrosion can occur via electrochemical reactions at the interface between a metal and an electrolyte solution.
- a thin film of moisture on a metal surface forms the electrolyte for atmospheric corrosion.
- Corrosion normally occurs at a rate determined by an equilibrium between opposing electrochemical reactions, anodic (metal oxidation) and cathodic (reduction of a solution species). These reactions can occur on one metal or on two or more dissimilar metals that are in electrical communication.
- Corrosion current can be used to generate a corrosion rate by assuming an electrolytic dissolution reaction involving a chemical species. Uniform corrosion across a metal surface allows calculation of the corrosion rate in units of distance per year.
- equivalent weight is a weighted average of the equivalent weights of the alloy components. If the dissolution is not uniform, corrosion products can be used to calculate equivalent weight.

- ASTM Standard G 102 Standard Practice for Calculation of Corrosion Rates and Related Information from Electrochemical Measurements can be used.
- An eddy current instrument and probe can be used for measuring corrosion by monitoring a conductivity curve and impedance plane and using one or more techniques such as single layer corrosion detection, two layer corrosion detection, a limited penetration method, dual frequency method, and/or a variable frequency method.
- Copper metal sample coupons with a surface area of 3.38 in were installed in a laboratory-scale liquid recirculating loop equipped with a reservoir capable of holding approximately 11 L total volume.
- the apparatus was designed to hold metal sample coupons in the path of flowing liquid at a chosen flow rate and temperature for chosen period of time. After exposure for an adequate period of time, the metal sample weight loss resulting from corrosion was used to calculate the corrosion rate.
- the exact conditions of the tests are listed in the Tables 1-3. For tests shown in all three tables, the temperature was 35°C, linear velocity was 7 gallons per minute (GPM) (3 ft/s), and the mass of treatment was 10 L. Synthetic water was used having 1170 ppm NaCl and 505 ppm NaHC0 3 , at pH 8.
