Temperature Effects on the Corrosion Inhibition of Mild Steel in Crude Oil Medium by the Seed Extract of Persea Americana (Avocado Tree)
Keywords:
Corrosion, Weight-loss method, Inhibition, AdsorptionAbstract
Weight-loss method was used in assessing the response to corrosion of samples of mild steel inserted in various concentrations (400, 600, 800 and 1000 ppm) of avocado seed extract in crude oil medium under various high temperature of 303, 313, 323, and 333 kelvin. The results show a negative correlation between temperature and corrosion inhibitor efficiency, with increased temperature leading to reduced corrosion effectiveness across all concentrations. Conversely, a positive correlation is observed between concentration and corrosion effectiveness, with higher concentrations resulting in enhanced corrosion protection. The findings suggest that elevated temperatures reduce the effectiveness of the avocado seed oil extract due to reduced solubility, reduced inhibitor adsorption rate on metal surface and potential degradation. The study highlights the importance of considering temperature and concentration factors when evaluating natural products as corrosion inhibitors in industrial applications, and suggests that avocado seed extract is an effective biodegradable corrosion inhibitor at high temperature.
