Abstract
Experiments were conducted with carbon steel to investigate the corrosion protection performance of five commercial chemicals as inhibitors in oil field effluent and aquifer waters. The effect of different inhibitor concentrations and flow velocity was determined using the disc electrode RDE method. The corrosion rate of carbon steel under stagnant and flow conditions was determined by the linear polarization resistance LPR method at a scan rate of 0.1mVs versus a saturated calomel electrode SCE. All experiments were conducted at 82C. Results indicated that a blend of ethoxylated amine inhibitor for the effluent water, alkylpyridiniumoxyalkylatedalkylphenol amine salts inhibitor was found to be the best for both the effluent and aquifer waters.
