In the FP7 project CAESAR, Air Products, BP, ECN, SINTEF and Politecnico di Milano worked together in the further development of the SEWGS process with the objective to reduce the energy penalty and the costs per ton of CO2 avoided to less than 25 through optimization of sorbent materials, reactor and process design and smart integration of the SEWGS unit in a combined cycle power plant. The most promising applications for the SEWGS technology are IGCC power plants and in combined cycles power plants fuelled with blast furnace top gas.<p>Extensive sorbent development work resulted in a new sorbent called ALKASORBp>+ p> with a high capacity resulting in cost of CO2 avoided for the IGCC application of 23. This is a reduction of almost 40 % compared to the Selexol capture case. Since ALKASORBp>+ p> requires much less steam in the regeneration, the specific primary energy consumption is reduced to 44 % below the specific energy consumption for the Selexol (2.08 versus 3.71 MJLHV/kgCO2).<p>From a technical point of view SEWGS is ready to move to the next development level, which is a pilot plant installation with a capacity of 35 ton CO2 per day. This is over 500 times larger than the current ECN's multi column SEWGS installation, but still 50 times smaller than an envisaged commercial scale installation. The pilot plant will prove the technology under field conditions and at a sufficiently large scale to enable further up-scaling, delivering both the basic design and investment costs of a full scale SEWGS demonstration plant.
