| 英文摘要 | ZIF-8/2-methylimidazole-ethylene glycol-water slurry was used for separating CO2 from CO2/N2 in a pilot-scale packed tower. In order to evaluate the tower efficiency and energy consumption of the packed tower in the CO2 capture process, firstly, the binary interaction parameters kCO2 of CO2 and ZIF-8 slurry were fitted by Peng-Robinson equation of state. Then the binary interaction parameters were related to Aspen Plus to simulate the multi-stage absorption process of CO2/N2. The calculation results show that in the pilot-scale packed tower, with only 5 theoretical plates, ZIF-8 slurry could reduce the CO2 concentration from 20%(mol) to less than 2%(mol), indicating the tray efficiency of the packed tower is 25%. About the energy consumption for the separation of CO2/N2 in the pilot plant, the results indicate that when desorption conditions were set at 333 K, 0.8 MPa, and 200 L/h, the CO2 capture equivalent work can be as low as 0.474 GJ/t CO2. When ZIF-8 slurry and MEA (30%(mass)) aqueous solution were used for CO2 capture under the same conditions, the CO2 capture equivalent work are 0.507 GJ/t CO2 and 0.957 GJ/t CO2, respectively. The CO2 capture equivalent work of ZIF-8 slurry is only 53% of that of MEA aqueous solution. 漏 2022, Editorial Board of CIESC Journal. All right reserved. |
