Abstract

Corrosion mitigation was evaluated at 80 °C in a naturally aerated 30 wt % monoethanolamine (MEA) solution with a CO₂ loading of 0.43 mol_CO2/mol_alkalinity for a FeCO₃-coated A106 carbon steel sample fabricated from solutions of NaHCO₃ and piperazine with CO₂ loading. The results showed that spontaneous passivation of A106 carbon steel was promoted by this FeCO₃ coating, which resulted in a Fe₃O₄ layer formation. FeCO₃ was metastable in this aerated MEA solution and eventually would transform into Fe₃O₄. Overall, the FeCO₃ coating reduced the corrosion rate by a factor of 70. In this case, a semi in situ process to form and/or recover a dense FeCO₃ layer to mitigate corrosion in a postcombustion CO₂ capture system is proposed. Because of its more environmentally friendly nature, easier process control, and faster FeCO₃ coating synthesis, NaHCO₃ is recommended as a FeCO₃ fabrication solution with respect to a piperazine solution with CO₂ loading.
