ABSTRACT
Corrosion study of the inhibition properties of Monoethylene glycol (MEG) in acid gas corrosion of wet gas pipeline (carbon steel) was performed. MEG is a thermodynamic hydrate preventer use in the stop hydrate formation in gas pipelines. The quest for energy encourages more offshore gas development and operation. The integrity of the entire pipeline for the transportation of gas from source to process facilities onshore is very important. With the conditions obtainable in the transportation of this gas severe corrosion can occur on the pipeline without proper inhibition by corrosion inhibitors or other corrosion method. This paper describes the efforts in preventing the corrosion of the gas pipeline in the presence of MEG using commercially available corrosion inhibitors and discusses the corrosion inhibition mechanisms. The effect of under dosing of the inhibitor is also highlighted using surface analysis techniques. The paper also describes the corrosion inhibition effects of MEG in certain specified conditions.

Keywords: Wet gas pipelines CO2 Corrosion Monoethylene Glycol (MEG) and Corrosion Inhibitor.
