Development of the Aqueous Processes for Removing NOx from Flue Gases.
Chappell, Gilford A.
A screening study was conducted to evaluate the capability of aqueous solutions to scrub NOx from the flue gases emitted by stationary power plants fired with fossil fuels. The report summarizes the findings of this laboratory program. The experimental program studied the following media for absorption of NOx from flue gases containing no NOx: Water; Metal hydroxides and slurries; Ammonia and 2-aminoethanol solutions; Acid solutions; and Salt solutions. In the scrubbing of flue gas containing NO2 and SO2, absorption of NO2-SO2 by sulfites, hydroxides, and carbonates was studied. Combined NOx-SOx scrubbing seems feasible using any of several hydroxide or carbonate systems provided NOx (NO) can be efficiently oxidized to NO2 upstream from the scrubbing unit. (NTIS)
