De-scaling, experimental, DFT, and MD-simulation studies of unwanted growing plant as natural corrosion inhibitor for SS-410 in acid medium

De-scaling will save economic losses caused by changing whole pipelines over time. By de-scales, can clean choked pipelines and the oil flow will be maintained. The SS-410 steel is used in the petroleum industry, tested for adsorption and corrosion studies. The preliminary corrosion tests were carried out using weight loss analysis and it was confirmed with the Electrochemical measurements 93% inhibition efficiency was achieved at 500 mg/ l concentration. The inhibition efficiency increases Ageratum houstonianum (A. houstonianum) extract concen-tration. The extract of A. houstonianum, obeyed the Langmuir's adsorption isotherm. Quantum chemical cal-culations show that the Beta-tertamethoxy phenyl, 6-hydroxyl 2,3,4,5-tetramethoxy Benzoic Acid (BHB) has the greatest inhibition efficiency investigated phytochemicals of A. houstonianum. The adsorption analysis done by atomic force microscope (AFM) supports the concept that the surface of SS-410 steel protected by the A. houstonianum extract in a destructive medium.

Automated summary

De-scaling is crucial in maintaining oil flow and reducing economic losses. The study shows that A. houstonianum extract can effectively inhibit corrosion of SS-410 steel, with increasing inhibition efficiency as the concentration increases.
