| 초록 | The concentration of CO2 in the earth’s atmosphere has been increased by combusting fossil fuels to generate electricity in power plants. In order to reduce net CO2 emissions into the atmosphere, several options have been suggested, which are reducing energy consumption by increasing the efficiency of energy conversion, switching to less carbon intense fuels, and using renewable energies. These options, however, may not be enough to mitigate global warming in the future, so the technology of CO2 capture and storage has been recently considered as an imminent and important option for mitigating global warming. Several methods have been developed for CO2 capture such as wet absorption, adsorption, membrane separation, and cryogenic separation. However, these methods have been faced on the limits of cost and energy required to treat the massive flue gas streams from fossil fuel-fired power plants. Recently, CO2 chemical absorption using dry regenerable solid sorbents has been studied as an innovative concept for CO2 recovery. CO2 is efficiently removed from the flue gas stream by reacting with solid sorbents while regeneration produces an off-gas containing only CO2 and H2O. The condensation of an off-gas generates highly pure CO2, which is suitable for chemical feedstock or sequestration. CO2 capture with a solid sorbent is cost-effective since solid sorbents are made of cheap alkali metals. Korea Institute of Energy Research (KIER) and Korea Electric Power Research Institute (KEPRI) have developed the dry sorbent CO2 capture system since 2002. We have finished the detail design of pilot plant based on the long-term operation and the several tests using bench scale unit (BSU) which treated 100 Nm3/h of flue gas. The pilot plant consists of a transport type carbonator and a bubbling type regenerator, which configuration is the same as the BSU facility. The pilot plant has been constructed at Hadong coal-fired power plant in Korea Southern Power Company. It can treat 2,000 Nm3/h of flue gas (0.5 MW scale). The construction has been done in late 2009 and the operation has been performed in 2010. |
