Conceptual Development of Flue Gas Cleaning for CO_2 Capture from Coal-fired Oxyfuel Combustion Power Plant

摘要

The conceptual development of flue gas cleaning system is described for CO_2 capture from PF oxyfuel combustion power plants. Important issues associated with the design criteria expected for the flue gas cleaning system are discussed based on different demands on the CO_2 end product depending on transport and storage options as well as plant operational issues. A rough techno-economical evaluation shows the expected impacts of different flue gas recycle and clean-up strategies on the investment costs of the flue gas cleaning system.
