Sažetak
During the life cycle, the structural elements of oil pipelines are exposed to various chemical, physical and biological influences that can cause their corrosion damage. As a result of corrosion, accidents such as fire, explosion, and toxic release can occur at oil pipelines, resulting in casualties, economic losses, and environmental problems, thus reducing the sustainability of pipeline transportation. To ensure the environmental and economic sustainability of the pipeline designing and selecting the best available systems and materials for pipelines and their corrosion protection systems is an important issue for the oil industry. This paper aims to study the corrosion process of mild steel in oil pipeline as different process parameters are simulated. FREECORPTM 2.0 corrosion prediction software was used for the simulation. The main features of this model include: prediction of corrosion rate caused by CO2, H2S, organic acids, i.e. CH3COOH, and/or O2, simulation of iron carbonate film and iron sulphide film growth and identification of major corrosive species by quantifying respective contributions from various species. The main parameters are temperature, time, pressure, pipe diameter and liquid velocity. The parameters of the aqueous solution are pH and concentration of corrosive species such as carbon dioxide, hydrogen sulphide, acetic acid, oxygen and concentration of Fe2+ ions. Based on specific input parameters, the uniform corrosion rate was calculated and the contribution of corrosive species to overall corrosion rate was determined.
