The study was carried out to develop a theoretical description of aqueous scrubbing processes for NOx emission control. The theoretical description is necessary to provide a basis for process development. The important chemical species present and the reactions they undergo in the sorption process were defined. An equilibrium model was developed so that the concentrations of the significant nitrogen-oxygen species present in the gas phase could be calculated under given conditions. A sorption mechanism and rate limiting step were proposed and an experimental program for testing them and providing engineering data was defined. Potential metal oxide sorbents were evaluated for effectiveness and efficiency on the basis of the thermodynamics of the sorption reactions. (Author)
