چکیده انگلیسی


• Bicarbonate and carbamate are produced at low carbon dioxide loadings.
• EAE aqueous solutions show similar behavior than amines with shorter alkyl group.
• Low amount of EAE causes a dramatic decrease in kL.

The present study aims to analyze the carbon dioxide absorption process in a chemical solvent based on 2-(ethylamino)ethanol, which is not commonly used in industry for this purpose, but it allows extracting interesting conclusions about the influence of absorption regime, physical properties or reagent chemical structure upon both hydrodynamic and mass transfer behavior in a bubble reactor. The influence of gas flow-rate upon bubble size distribution or gas hold-up allows understanding how the behavior of this type of reactors is and how they can influence the overall process. In this way, in analyzing the predominant reaction mechanism, the behavior of mass transfer coefficient can be known and understood as to why, for this kind of chemical solvent, a dramatic decrease of this coefficient is produced only with the presence of a small amount of amine.
