(54ak) Study of the Effects of Flow Conditions on the Performance of Corrosion Inhibitors in CO2 Environment

Major process safety incidents have been caused by corrosion all over the world. Despite the increasing knowledge in corrosion, efforts are still needed to understand different damage mechanisms and their control methods. One of the most common active corrosion mitigation techniques in refineries is the use of corrosion inhibitors. Film-forming corrosion inhibitors create a protective layer that can be influenced by different flow characteristics and flow regimes. These changes in hydrodynamic conditions have an effect on the performance of corrosion inhibitors; therefore, more study is required to understand the behavior of corrosion inhibitors under various flow conditions and corrosive environments. This work focuses on the study of different flow parameters such as flow velocity and its influence on corrosion inhibitors efficiency under CO₂ environment_. The experimental work will be performed in a rotating cylinder electrode (RCE) that allows to simulate different flow effects. Electrochemical techniques and surface analysis will be used to understand the behavior of the inhibitor under different inhibitor concentrations and flow conditions. The objective isto analyze the adsorption mechanism of the selected inhibitor and its efficiency to help in the fundamental understanding of the performance of CO₂ corrosion inhibitors.
