• Abstract:

  In industry in general and in the oil industry, corrosion has been a major costly problem, causing financial losses. In this context, this study sought to evaluate Sargassum vulgare, collected on the coast of Alagoas, as a corrosion inhibitor for metallic structures on oil platforms, more specifically in carbon steel hydrocarbon production pipes. For that, synthetic produced water was used in the absence and presence of the proposed inhibitor and gravimetric technique for evaluation of the test specimens. The study pointed out that the presence of algae reduced the percentage mass loss, the accumulated load and the corrosion current of the specimens, consequently impacting the reduction of corrosion in steel. Thus, the evaluated seaweed acted as a green corrosion inhibitor.
