Integrated Gasification Combined Cycles (IGCC) offer the potential of utilizing the heating value of a high-carbon containing fossil fuel to transform it into electrical power with a higher efficiency than pulverized coal boilers, reducing the specific emissions of the plant. Emissions can be driven to substantially lower levels when CO2 capture technology is implemented in the plant. Research and technology development focus on different pathways to capture carbon related emissions in IGCC. A growingly interesting option consists of inherent carbon capture where a metallic oxygen carrier withdraws O2 from the compressed air stream releasing it in a N2 free environment where combustion of syngas takes place, also known as chemical looping combustion (CLC). This can be achieved by a cluster of gas switching combustion (GSC) reactors alternatively in reduction and oxidation mode achieving a steady state operation. Although the GSC provides an inherent separation of combustion gases and air, a certain mixing with depleted air (consisting mainly of N2) is unavoidable as a consequence of the switching valve mechanism. When fluidized beds are employed in the reactor cluster, this mixing effect is even more pronounced because of the better mixing properties of this reactor type. After heat is retrieved from the combustion gases stream and condensed water is knocked out, a purification unit is necessary to increase the CO2 concentration to at least 96% mol, which is the typical specification for cost effective CO2 transport.
