| 제목 | Stripper Analysis of Post Combustion CO2 Capture Process with Operating Condition Change |
| 초록 | The necessity of heat and energy requirement for the post-combustion capture process causes 20-25% of power de-rate by steam extraction from power plants. Especially, stripper reboiler is the most energy-intensive unit and has been known to use less energy with higher operating pressure. In this study, the optimal operating pressure of the stripper is proposed to minimize power de-rate of power plants. The CO2 capture process combined with a 550 MW coal-fired power plant was simulated. The results show that intermediate pressure is optimal in case of integrated process, not the highest operable pressure. With optimal pressure, the power de-rate minimization is up to 14.7% relative to the base case. This research was supported by a grant from the LNG Plant R&D Center funded by the Ministry of Land, Transportation and Maritime Affairs (MLTM) of the Korean government, by the Energy Efficiency & Resources Core Technology Program of the Korea Institute of Energy Technology Evaluation and Planning(KETEP) granted financial resource from the Ministry of Trade, Industry & Energy, Republic of Korea (No. 2010201020006D). |
