N2 - Oxyfuel combustion in a pulverised fuel coal-fired power station produces a raw CO(2) product containing contaminants such as water vapour plus oxygen, nitrogen and argon derived from the excess oxygen for combustion, impurities in the oxygen used. and any air leakage into the system There are also acid gases present. such as SO(3), SO(2), HCl and NO(x) produced as byproducts of combustion. At GHGT8 (White and Allam, 2006) we presented reactions that gave a path-way for SO(2) to be removed as H(2)SO(4) and NO and NO(2) to be removed as HNO(3) In this paper we present initial results from the OxyCoal-UK project in which these reactions are being studied experimentally to provide the important reaction kinetic information that is so far missing from the literature This experimental work is being carried out at Imperial College London with synthetic flue gas and then using actual flue gas via a sidestream at Doosan Babcock's 160 kW coal-fired oxyfuel rig The results produced support the theory that SO(x) and NO(x) components can be removed during compression of raw oxyfuel-derived CO(2). and therefore, for emissions control and CO(2) product purity, traditional FGD and deNO(x) systems should not be required in an oxyfuel-fired coal power plant (C) 2009 Elsevier Ltd All rights reserved
