Project overview

The CAESAR project includes six work packages (WP)

WP1 (Materials development): Develop optimum sorbent/catalyst system for application in SEWGS based on syngas from natural gas, coal, refinery residues, or blast furnace gas feeds. Minimal steam use for purge and rinse flows (in total less than 2 mol steam / mol CO2).


WP2 (Reactor design): The development of a SEWGS reactor model that is validated against experimental results. More than 2000 cycles stable operation of the single column unit at steam/CO2 ratio of less than 2 and more than 95% CO2 capture. Reactor design for SEWGS in one or more of the applications.


WP3 (Process design): Experimental validation on the multi-column set-up. Develop a SEWGS process cycle, with a total steam/CO2 ratio of 2. Experimental demonstration of the cycle on the multi-bed SEWGS test rig. Development and demonstration of the cyclic SEWGS process for application in coal gas and blast-furnace gas.


WP4 (Application and process integration): Development of flow sheet models and costing tools for the new SEWGS set-up for natural gas fired power generation and for coal gas and industrial applications (refinery residues gasification and blast-furnace gas). SEWGS system with an efficiency penalty of less than 5% point and capture costs of 15€/ton CO2 or an IGCC with WGS and separation & compression.


WP5 (pilot plant design): Deliver a mechanical reactor design for a pilot plant for one of the applications studied.


WP6: Project management and dissemination: public reports, peer-reviewed papers, Organisation of  EU CCS conferences in collaboration with other FP7 projects in the CO2 capture field.
