Demonstration of Long-Term Operation with a Potassium-Based Dry Sorbent for CO2 Capture in Two Interconnected Fluidized Bed Reactor |
| 초록 |
The CO2 removal in dry sorbent CO2 capture system consists of two reactors for carbonation and regeneration. We used spray-dried sorbents contained alkali carbonate, which was supplied by KEPRI in order to see the sorbent performance in continuous operation mode with solid circulation. The process with 2Nm3/h of gas treatment capacity has been continuously operated during 50 hours, circulating potassium-based solid sorbents between a fast fluidized-bed carbonator and a bubbling fluidized-bed regenerator. 13% inlet CO2 concentration in a flue gas stream has been maintained during continuous operation. The effects of CO2 removal on the solid circulation rate and the regeneration temperature were examined. Increasing the solid circulation rate and the regeneration temperature gave rise to the increase of the overall CO2 removal. |
