چکیده انگلیسی
An rotating packed bed (RPB) was applied to capture CO2 from the flue gases of natural gas power plants containing 4Â vol% of CO2 using an aqueous solution with mixed absorbents piperazine (PZ) and diethylenetriamine (DETA)Â in this study. The experimental results showed that PZ/DETA with 4.0Â m/4.0Â m, as the most promising formulation, not only exhibited higher CO2 capture efficiency and capacity but also showed lower regenerated energy in an RPB with 54.8% lower than the most common used absorbent of 7.0Â m monoethanolamine (MEA). The effects of absorbent concentration, lean loading and regeneration in an RPB were all investigated. Based on the Aspen Plus simulation to 7.0Â m MEA with various loadings, a packed bed (PB) required 4.6 times the volume of an RPB to achieve the same capture efficiency at the same operating conditions; the CO2 capture efficiency and amount using an RPB were 63% and 4.6 times higher, respectively, than those for the same volume PB, indicating the superiority of an RPB to treat low CO2 concentration flue gases.
