Abstract
Abstract Present work analyzes the behavior of several gas-liquid-liquid systems for carbon dioxide separation using chemical absorption. The type of amine center in a solvent with two liquid phases (organic and aqueous) shows a high importance in relation to the overall behavior. The experimental results for these solvents have been compared with a previous study using octylamine in the chemical solvent because it has shown suitable results for carbon dioxide loading, absorption rate and energy cost associated to solvent regeneration. Present study analyzes the carbon dioxide absorption mechanism in multiphasic reactors (specifically G-L-L) using different types of amines in order to understand the overall behavior that involves steps of mass transfer and chemical reaction.
