Corrosion inhibitors are used in the petroleum industry in several steps, including drilling, production, transportation, and storage of oil and gas. [ 2 ] [ 3 ] They can mitigate different types of corrosion in the petroleum industry, such as generalized corrosion, pitting corrosion, erosion corrosion, stress corrosion, galvanic corrosion ...
The effectiveness of a corrosion inhibitor depends on fluid composition and dynamics. Corrosion inhibitors are common in industry, and also found in over-the-counter products, typically in spray form in combination with a lubricant and sometimes a penetrating oil. They may be added to water to prevent leaching of lead or copper from pipes. [2]

With oxygenated treatment, oxygen is injected into the feedwater to keep the oxygen level between 30 and 50 ppb. OT programs are most commonly used in supercritical (i.e. >3250psi) power boilers.
Scale inhibitors are specialty chemicals that are added to oil production systems to delay, reduce and/or prevent scale deposition. [ 4 ] acrylic acid polymers, maleic acid polymers and phosphonates have been used extensively for scale treatment in water systems due to their excellent solubility, thermal stability and dosage efficiency.
NACE International Standard TM0208 defines volatile corrosion inhibitor (VCI) as a chemical substance that acts to reduce corrosion by a combination of volatilization from a VCI material, vapor transport in the atmosphere of an enclosed environment, and condensation onto surface in the space, including absorption, dissolution, and hydrophobic ...
Low pH (acidic) aggravates corrosion, so use corrosion coupons [clarification needed] to monitor corrosion type, rates and to tell correct chemical inhibitor is used in correct amount. A corrosion coupon is a small piece of metal exposed to the process so to evaluate the effect the corrosive conditions would have on other equipment of similar ...
Corrosion prevention measures, including Cathodic protection, designing to prevent corrosion and coating of structures fall within the regime of corrosion engineering. However, corrosion science and engineering go hand-in-hand and they cannot be separated: it is a permanent marriage to produce new and better methods of protection from time to time.
