Abstract
In recent years, the corrosion problem of equipment and pipeline caused by oilfield produced water is becoming increasingly serious. In this work, corrosion inhibitor of triazine, synthesized from formaldehyde and ethanolamine, was evaluated using weight-loss techniques. The triazine was found to inhibit the corrosion of mild steel in simulated oilfield produced water. The adsorption of inhibitor was studied, which was consistent with the assumption of Langmuir adsorption model. Thermodynamic parameters of corrosion inhibition process were further calculated and analyzed, which indicated that adsorption of triazine inhibitor was exothermic, spontaneous and physical process.
