Mathematical modeling of CO2 corrosion with NORSOK M 506

Abstract

The consequences of corrosion are catastrophic. Also costs to the global economy reached "$2.5 trillion, or world GDP's 3.4%". Despite the magnitude of the corrosion cost, it can be concluded that scientific studies on corrosion prevention are quite limited, except for high-risk sectors such as aviation and the fuel oil industry. It is important to fight against corrosion to ensure the safe operation of oil-carrying pipelines under the sea, and to prevent accidents and environmental damage. As a result of developing industry conditions and increasing needs, modeling corrosion is a very effective method for the prevention of corrosion. Industry, research companies, and universities have developed many corrosion rates and prediction models. One of them is the NORSOK M 506 model. In this study, the NORSOK M 506 CO2 corrosion prediction model and the experimental results conducted by Nešić, Solvi and Enerhaug in 1995 were compared in terms of CO2 corrosion rate. The results showed that the mathematical corrosion model calculated nearly six times higher than the experimental studies.
