Scrubbing System Design for CO2 Capture in Coal-Fired Power Plants
Zusammenfassung
Within the last decades a continuous tightening of environmental regulations has been observed in several countries around the world. These include restriction of anthropogenic CO2 emissions, since they are considered responsible for intensifying global warming. Coal-fired power plants represent a good possibility for capturing CO2 before it is emitted in the atmosphere, thereby contributing to combat global warming. This work focuses on reducing the CO2 emissions of such a power plant by 90 %. For this purpose a hard coal power plant is retrofitted with a chemical absorption using different solutions of piperazine promoted potassium carbonate. The resulting power plant’s efficiency losses have been accounted for. A comparison of different scenarios such as the variation of operating parameters offer an insight in detecting suitable operating conditions that will allow to minimize Efficiency penalties. Simulation details are provided along with a technical and an economic Analysis.
