The target of this work is to evaluate three analytical techniques, ICP-MS, SEM-EDS and XRD, which can be applied in corrosion monitoring of ethanolamine based post-combustion CO2 capture plants. The work is based on analyses of the solvent and 316 SS cylinders used in thermal degradation experiments. ICP-MS is used for the determination of total Fe, Cr and Ni of the solutions as an indication of...
Amine degradation and corrosion can be a severe operational problem in the CO2 absorption process. In this paper the effect of MEA's degradation products on corrosion is studied. Different solutions of MEA 30wt% containing also 1wt% of a specific degradation product were placed in 316 stainless steel cylinders and stored in a thermostat chamber at 135oC. Samples are analysed for Fe, Cr, Ni and Mo...
