CO2 Corrosion Analysis of Water Samples from the Western Caspian Sea: Insights from Sumqayit, Neftchala, Bilgah, and Pirallahi

Corrosion caused by carbon dioxide (CO2 ) poses considerable problems to infrastructure in maritime settings, significantly impacting the oil and gas industries. This study examines the CO2 corrosion rates in water samples obtained from four significant sites in the western Caspian Sea: Sumqayit, Neftchala, Bilgah, and Pirallahi. We utilised gravimetric analysis to quantify the corrosion rates of steel plates submerged in these fluids for five hours at ambient temperature. The findings indicated differing degrees of corrosion aggressiveness throughout the locales, with Sumqayit and Neftchala demonstrating the most outstanding rates. This underscores the geographical variability in water chemistry and its influence on corrosion. Comprehending these patterns is vital for formulating tailored corrosion control strategies, especially in industries such as oil, gas, and transportation, where the durability of infrastructure is paramount. The work establishes a foundation for future investigations into corrosion inhibitors, providing insights for improving protective strategies in the industrial settings of the Caspian area.
