Thermal Degradation of Single and Blended Amines for CO2 Capture Process

Author(s): Nabil El Hadri, Hessa Mohammed Al Shehhi, Dang Viet Quang, Mohammad Abu-Zahra.

Abstract:

Thermal degradation of aqueous amine solutions of monoethanolamine (MEA) 30 wt% and 50 wt%, piperazine (Pz) 30 wt% and their blend (MEA 10 wt%/20 wt% Pz) with CO2 have been studied at 140C. A lab-scale experiment was performed in order to study the thermal degradation at the stripper operating conditions in post-combustion process. Experiments were done at different conditions (amine concentration, time exposure) and a quantification of the degradation products was obtained in order to understand the different impact of these parameters. Thermal degradation products were identified by gas chromatography - flame ionized detector (GC-FID). It has been shown that Pz is more stable against thermal degradation in comparison with MEA.

Keywords: Amine concentration, degradation products, monoethanolamine, piperazine, thermal degradation.
