Corrosion of Carbon Steel in Aqueous Solutions of Ionic Liquids and Alkanolamine Containing Carbon Dioxide
Ionic Liquids, MEA, Electrochemical Techniques, Carbon Steel and CO2 Corrosion
The new data for corrosion of carbon steel are reported in aqueous mixed solution containing (0.1-1.0 M) 1-Butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]), (0.1-1.0 M) 1-Butyl-3-methylimidazolium dicyanamide ([bmim][DCA]) and 4M monoethanolamine (MEA) at 60 ◦C and CO2 loading 0.55 mol/mol using electrochemical techniques; which were impedance spectroscopy and polarization curves. The experimental results show that the corrosion of carbon steel decreased with increasing concentrations of both ([bmim][DCA]) and ([bmim][BF4]) from 0.1-1.0 M. Also the surface analysis scanning electron microscopy (SEM) was carried out to characterize the corrosion products layers on the metal surface. Ionic liquids with dicyandiamide anion provided a better protection than tetrafluoroborate. These results suggest that the nature of the anion of ILs have influence on the corrosion of carbon steel.
