摘要：

Carbon dioxide emission reduction has become a hot issue and attracted international attention. In recent years, chemical absorption methods gradually dominate the market since they have advantages of high efficiency, widely adaptation and mature technologies. CO2 absorption experiments were conducted in a rotating packed bed using aqueous sodium glycine as a solvent. Effects of rotational speed, concentration and temperature of absorption solution, and gas-liquid ratio on CO2 absorption efficiency were investigated. The experimental results indicate that the absorption efficiency of CO2 increases with the increasing of rotational speed and the absorption efficiency becomes stable when the rotational speed is 1000 r·min-1. The absorption efficiency of CO2 also increases with the increase of absorption solution temperature, which can reach to over 83% at 90℃. Under certain operation conditions, the absorption efficiency of CO2 increases slightly with the increase of absorption solution concentration, while it decreases first and then becomes a constant with the increase of gas-liquid ratio. ©, 2015, Zhejiang University.
