Experimental, modeling and RSM optimization of CO2 loading for an aqueous blend of diethylenetriamine and 3-dimethyl amino-1-propanol
Post-combustion CO 2 capture by aqueous amine solvent is one of the most promising methods for mitigating the presence of CO 2 in the environment. In this work, a novel amine blend of Diethylenetriamine and 3-Dimethyl amino-1-propanol was selected. Experiments were performed in the temperature range...
