Technique
Description
Applicability
a.
Condensation
See Section 12.1
Generally applicable
b.
Wet scrubbing
See Section 12.1. In many cases, scrubbing efficiency is enhanced by the chemical reaction of the absorbed pollutant (partial oxidation of NOX with recovery of nitric acid, removal of acids with caustic solution, removal of amines with acidic solutions, reaction of aniline with formaldehyde in caustic solution)
c.
