PHOSNOX
The PHOSNOX process, developed in 1990, removes NOx from Flue Gas simultaneously with SOx removal in existing wet FGD systems. NO is oxidized into more soluble NO2, by the addition of yellow phosphorus P4 to the scrubbing solution. Phosphoric acid is a recoverable byproduct. Process would be cheap and effective, but perceived safety issues have blocked further development. (Bechtel was actively promoting this for some time.)
