CO2 chemical absorption in 3-amino-1-propanol aqueous solutions in BC reactor

• We analyze CO2 capture by 3-amino-1-propanol aqueous solutions.
• An increase in interfacial area is observed with CO2 loading.
• The main reaction product is bicarbonate ion.
• A new regeneration process shows similar behavior than the conventional one.

The present paper analyzes the overall carbon dioxide absorption process in aqueous solutions of 3-amino-1-propanol using a bubble column reactor (BCR). These studies focus on the absorption rate, the reactor hydrodynamics, the speciation during the experiments, the changes in liquid phase temperature and the solvent regeneration to be used in new absorption cycles. Some of these studies have allowed knowing the importance of each involved reaction in the mechanism, while others allow evaluating the potential use of this amine for carbon dioxide capture in an industrial process.
