MATHEMATICAL MODELING AND SIMULATION OF PROCESSES AFFECTING THE CORROSION KINETICS IN OIL PIPELINES ON THE ABSHERON PENINSULA

The article presents the mathematical modeling and simulation of processes influencing the corrosion kinetics in oil pipelines on the Absheron Peninsula.It has been determined that a high concentration of chloride ions and an acidic environment intensify the kinetics of corrosion.Under the influence of radiation, the main parameters of adsorption undergo significant changes.The type of crystal lattice on the surface directly affects the kinetics and energy of adsorption.Dislocation processes within crystal structures can alter the adsorption mechanism by modifying the surface characteristics of the material.Dislocation lines create local variations in energy and stress on the crystal surface, leading to preferential accumulation of adsorbates in these regions.The stress fields generated as a result of dislocation processes reduce the energy barrier for adsorption on the surface, thereby increasing the adsorption rate.Simulation results indicate that as the stress level rises, the degree of surface coverage by adsorbates also tends to increase.This finding demonstrates the strong influence of the dislocation mechanism on adsorption.Thermodynamic parameters, particularly temperature and Gibbs free energy, have a direct effect on adsorption and the kinetics of corrosion.
