Abstract

This research explores the sustainable application of Gmelina arborea and Wire Croton plant extracts as green corrosion inhibitors for oil pipeline infrastructure. Steel samples were exposed to different corrosive environment (acidic, alkaline, saline, and neutral) to simulate the diverse conditions faced by pipelines. Three different concentration ratios of the extract (50:50, 60:40, and 40:60) were applied into the corrosive environment to determine their efficacy in inhibiting pipeline corrosion. Gas Chromatography-Mass Spectrometry (GC-MS) was used to identify the phytochemicals responsible for corrosion inhibition in the Gmelina arborea and Wire Croton plant extracts. Additionally, surface morphology changes were evaluated using Scanning Electron Microscopy (SEM) to assess the protective layers formed by the inhibitors on the steel surface. The results reveal that the 60:40 ratio combination of Gmelina arborea and Wire Croton significantly reduces corrosion rates with highest inhibition efficiency, offering a sustainable eco- friendly alternative for corrosion control in the oil and gas industry. By mitigating corrosion, this study addresses not only environmental concerns but also provides a cost-effective solution, reducing maintenance costs and extending the lifespan of oil pipeline infrastructure. It underscores the potential of bio-based inhibitors as a viable approach to enhancing the longevity and safety of pipeline systems, ultimately lowering the economic burden on the industry.
