Murillo Villuendas, Ramón Grasa Adiego, Gemma Abanades García, Juan Carlos Post-combustion CO2 capture Ca-looping cycle 10th International Conference on Greenhouse Gas Control Technologies [EN] This work analyses a Ca-looping system that uses CaO as regenerable sorbent to capture CO2 from the flue gases generated in an existing supercritical power plant. The CO2 is captured by CaO in a CFB carbonator while coal oxycombustion provides the energy required to regenerate the sorbent. Part of the energy introduced into the calciner can be transferred to a new supercritical steam cycle to generate additional power. Two case studies based on a scenario of low solid circulation rate between reactors have been integrated with the new supercritical steam cycle. Efficiency penalties, mainly associated with the energy consumption of the ASU, CO2 compressor and auxiliaries, can be as low as 7.5 percentage points of net efficiency when working with low CaCO3 make-up flows and integrating the Ca-looping with a cement plant that makes use of the solid purge. 70 % of the CO2 generated in the existing plant is captured under these conditions; with an overall CO2 capture over 86 %. This work is partially supported by the European Commission under the 7th Framework Programme (CaOling project). I. Martínez thanks Diputación General de Aragón for the F.P.I. fellowship.
