Abstract

Solvent degradation and metal corrosion are critical concerns of a post-combustion CO₂ capture process. Systemic analysis indicated that oxidation, nitrosation, and corrosion reactions occur or initiatethrough a radical reaction and thus addition of a radical scavenger is expected to work effectively to avoid these reactions. Here, for the first time, a multifunctional organic compound (CAER additive) has been evaluated as an inhibitor. The corrosion rate of A106 in 5 mol/kg MEA was lowered by one order of magnitude when 5mM inhibitor was added. Oxidation of 5 mol/kg MEA was monitored based on accumulation of formate concentration in the solution and formate levels were below the detection limit when CAER additive was present. Furthermore, the same additive was found to inhibit nitrosation of 5 mol/kgmorpholine with 100 ppm of NO₂ gas by 91% in 6 h.
