In the oil and gas industry, carbon dioxide (CO₂) corrosion is a well-known issue, causing general corrosion and localized corrosion. CO₂ can be dissolved in the aqueous phase, forming carbonic acid (H₂CO₃). This can be dissociated into a hydrogen ion and a carbonate ion that can promote the oxidati...
