Non-oxidative Thermal Degradation of Amines: GCMS/FTIR Spectra Analysis and Molecular Modeling

Aqueous amino solvents, such as monoethanolamine (ETA/MEA), methyl diethanolamine (MDEA)
or amine blends, are the most widely used solvents in commercial CO2 or acid gas separation
applications. These commercial solvents have various disadvantages, such as the possibilities of
the solvent to be degraded. This research examines the impact of non-oxidative thermal degradations
on the performance of the CO2 absorption and the degradation mechanism of amine
solvents. The impact of degradation was conducted by measuring the CO2 solubility of solvent
that had been heated to 120°C for 2 h. Although the performance of CO2 absorption was not
significantly reduced, the degradation of amines was found. Supported by Fourier Transform
Infrared (FTIR) and Gas Chromatography/Mass Spectrometer result, the suspected products of
non-oxidative thermal degradation of MDEA were MEA and acetone.
