Abstract |
Technical notes pertaining to, and developed during, a study of the theoretical description of aqueous scrubbing processes for NOx emission control are presented. The ten notes are as follows: Review of the literature on experimental studies of the aqueous absorption of nitrogen oxides; Gas phase equilibrium in the system NOx-H2O; Compilation of thermodynamic properties for compounds of interest in nitrogen oxides aqueous absorption processes; High temperature behavior of anhydrous and hydrated nitrites and nitrates; Material balance calculations for NOx aqueous sorption in a packed tower; Selected values for equilibrium constants used in the aqueous equilibrium formulation; Vapor film mass transfer coefficients for HNO2 and HNO3 in a packed tower; Results of literature search on aqueous sorption of nitrogen oxides; Calculation of decomposition pressures over metal nitrates and nitrites and; Listing of subroutines for the gas phase equilibrium model.
