A Complex Imidazoline Corrosion Inhibitor in Hydrochloric Acid Solutions for Refinery and Petrochemical Plant Equipment

摘要

A newly developed imidazoline inhibitor was introduced in this article. Its inhibition effects for mild steel were investigated by weight loss measurements with a different additive dose, immersion time, corrosive media temperature, and concentration of HC1 solution. The results showed that this imidazoline inhibitor was suitable for mild steel, which was usually used in petrochemical plant equipment in acid media, and had an excellent inhibiting effect at a concentration of 100 mu g/g, 6 hr immersion time, and with the concentration of 0.0001 M HCl solution at 50 deg C.
