COMPARISON OF DIFFERENT TECHNIQUES FOR THE IMPROVEMENT OF THE CO2CORROSION BEHAVIOR OF CARBON STEELS IN OIL AND GAS INDUSTRY

摘要

CO2 internal corrosion behavior of carbon steels protected by various methods has been studied.The purpose is to evaluate if a new technology based on sol-gel materials can be used as viable option toprevent CO2 corrosion in gas and oil pipelines. The corrosive process was compared to that obtained inpresence of asphaltene and corrosion inhibitor films. Pressured experiments (weight loss) and linearpolarization resistance tests were carried out.
