Abstract
Present research work analyzes carbon dioxide chemical absorption using different types of alkanolamines (primary, secondary and tertiary) with the presence of several organic co-solvents. These additional substances have been considered as interesting additives in previous works that can produce improvements upon the overall carbon dioxide separation process. On the basis of this hypothesis, this research analyses the influence of these solvents upon the absorption process using two parameters: absorption rate and carbon dioxide loading. Two different types of co-solvents have been tested analyzing the effect of their concentration in the liquid phase. Also the influence of these substances upon the reaction mechanism has been studied.
