Abstract:
Every industry in the world is experiencing a huge problem with corrosion, which is the degradation of materials to their atomic components, but the petrochemical industry is particularly affected. Crude storage tanks play a crucial role in the petrochemical process since they keep everything functioning properly. Storage tanks are extremely vulnerable to corrosion because of the aqueous environment, which could lead the petrochemical industry to significant financial loss. Corrosion in the bottom plates of storage tanks for crude oil and refined products is directly related to water present in the crude that is transported with the products, whether in suspended or condensed form. After processing, crude oil taken from wells and kept in a storage tank for 24 to 72 hours before being transported. Crude extracted from reservoirs contains microorganisms as well as salt, sand, carbonates, and chlorides. Because the nozzle for draining produced water is located above the bottom plate, produced water accumulates in the tank's bottom all year long. During the settling process, slugs progressively accumulate in the tank's bottom and corrode the bottom plate. This study's objectives were to assess the underlying causes of corrosion in a crude storage tank's bottom plate as well as the rate of corrosion in various corrosive media, including crude, produced water, and solution (crude represented 80% of corrosion and produced water 20%) by using weight loss and linear polarization resistance methods. Additionally, the application and analysis of various corrosion control measures, such as various corrosion inhibitor types (oil base, water base), and fiber reinforcement polymer (FRP) coatings, are the main goals of this study. The findings demonstrated that FRP coating, as opposed to corrosion inhibitors, reduced the specimen's rate of corrosion. By using FRP coating, the bottom plate's corrosion rate was decreased by 93 (%) and the results were compared to those from other methods.
