Study of the Effects of Flow Conditions on the Performance of Corrosion inhibitors under CO2 Environment
Abstract
Major process safety incidents have been caused by corrosion all over the world. These incidents are usually related to loss of containment of highly flammable liquids or gases, causing severe damages to the environment, impacts on people and monetary losses. Despite the increasing knowledge in corrosion, efforts are still needed to understand different damage mechanisms and their control methods. This work focuses on the study of different flow parameters such as flow velocity in a brine solution saturated with CO2 in presence of a non-toxic corrosion inhibitor. The tests will be performed using a rotating cylinder electrode which is a well-defined apparatus to study changes in hydrodynamic conditions in a pipe. Electrochemical techniques such as Electrochemical Impedance Spectroscopy (EIS) coupled with surface images will be used to understand the behavior of the inhibitor under different flow velocities. The objective isto enhance the fundamental understanding of the damage mechanisms present in the in downstream processes of oil and gas industry. The experimental results from this work would allow developing a model describing the corrosion behavior.
