چکیده انگلیسی
This study investigated the absorption heat, equilibrium CO2 solubility, absorption and desorption rates, cyclic capacities, heat duty, and absorption kinetic modeling of amine blends containing AMP and DETA. The AMP and DETA concentrations were varied (1-2.5â¯kmol/m3 and 0.5-2â¯kmol/m3, respectively) while the total amine concentration was constant at 3â¯kmol/m3. The absorption experiment was conducted at 15â¯%v/v CO2 and 313â¯K while the desorption temperature was at 363â¯K. Experimental results revealed that the absorption rates, cyclic capacities and desorption rates of some AMP-DETA blends were higher than those of 5â¯kmol/m3 MEA. The absorption heat of the blends is comparable to that of MEA while the heat duty of some AMP-DETA blends are much lower than that of 5â¯kmol/m3 MEA. The optimal amine blend was confirmed to be 2â¯kmol/m3 AMP - 1â¯kmol/m3 DETA. A model similar to the power law kinetic model showed that CO2 composition in the feed gas affected the initial absorption rates as compared to AMP/DETA molar concentration ratio. The model predicted the initial absorption rate with a %AAD of 0.52%. These results provide good prospects for AMP-DETA blends towards CO2 capture.
