MEG delivery system
Baker Hughes was asked to suggest a corrosion inhibitor for the largest monoethylene glycol (MEG) delivery system in Australia. The MEG was being used to treat an extensive wet gas pipeline system. The gas contained 3% CO2 and required a robust corrosion control program.
To meet economic goals, the pipeline operator needed a reasonably priced corrosion inhibitor solution that would remain active in the MEG after regeneration. In addition, the operator required a corrosion inhibitor that would not cause emulsions, the formation of solids or foam in the MEG regeneration system.
Baker Hughes drew on its extensive knowledge of treating MEG systems around the world to identify a set of product candidates to treat this particular system. After laboratory testing to select the most cost-effective product and ensure its compatibility and performance under system conditions, the CGW24010 corrosion inhibitor was identified as the best product for this system.
Working closely with the operator’s integrity management team, Baker Hughes conducted a field trial to validate the performance of the CGW24010 corrosion inhibitor against key performance indicators (KPI).
