Abstract

A Nonlinear Regression Analytical model was used to simulate the corrosion rate of CO2 flowing through a pipeline at different operating conditions. The model was formed by applying the simple current-resistance relationship which was further simplified to obtain an appropriate expression for estimating the corrosion rate of a pipeline in relation to the partial pressure of the gas at different temperatures (30–37 °C). Field conditions were validated against simulated results and based on the findings, the model proved to be an accurate tool for determining the corrosion rate of CO2 for curvilinear pipe of 3 km length transporting fluids having similar gas composition. Based on the estimated corrosion rates, the model's accuracy lies in the range of 96–99%. Also, from the results, there seem to be an approximate linear relationship/positive correlation between the corrosion rate of CO2 and, the system temperature and CO2 partial pressure.
