Corrosion inhibitors were evaluated in a flow loop apparatus, for a subsea production flowline application in a major gas condensate project. The design temperature for the production was 115 degree C, with a considerable carbon dioxide (CO2) presence. Acceptable corrosion inhibitors were identified in this examination. However, the evaluation demonstrated that the presently available green inhibitors were not suitable. The corrosion performance was strongly dependent on temperature, especially above approximately 90 degree C. Most inhibitors performed well (<0.025 mm/y or 1 mpy) in the static environment, but exhibited poorer performance in the flowing (4 m/s) condition. Elevated temperature performance was associated with separation of the hydrocarbon and aqueous phases. This study was influenced by the general lack of corrosion inhibitor partitioning data available in the industry.
