The capture/separation step for carbon dioxide (CO2) from large-point sources is a critical one with respect to the technical feasibility and cost of the overall carbon sequestration scenario (capture followed by storage). For large-point sources, such as those found in power generation and industrial operations, the carbon dioxide capture techniques should possess the potential for improved efficiency and costs as compared to more conventional technologies. The techniques can have wide applications, for example capture/separation of carbon dioxide from flue gas (postcombustion, for example from fossil fuel-fired combustors) and from fuel or synthesis gas (precombustion, such as integrated gasification combined cycle – IGCC). This session will concentrate on new or improved methods of CO2 capture from advanced power systems and large industrial plants that can significantly reduce CO2 capture costs and associated energy requirements. Novel concepts are being developed including, but not limited to, wet scrubbing with either chemical or physical absorption; chemical absorption or adsorption with solid sorbents; separation by membranes; oxyfiring of fossil fuels; and chemical looping. Presenters are encouraged to submit in the above technological areas or in any other areas that apply to the general advancement in carbon capture.
