This work explores the promise of aqueous solutions of blended methyldiethanolamine (MDEA) and piperazine (PZ) as a costeffective absorbent for carbon dioxide (CO2) capture from power plant flue gas streams. The hanging film experiment is used to study the law of the corrosion of blended MDEA/PZ containing different CO2 loading with carbon steel and stainless steel. Electrochemical corrosion experiments were carried out using the potentiodynamic polarization technique for carbon steel corrosion measurements. Many factors are taken into account, including temperature, CO2 loading, mixing ratio of blended MDEA/PZ. The results show that the corrosion rate of carbon steel increases with solution temperature, concentration of PZ, CO2 loading of solution.
