Application & Dosage
Diesel Exhaust Fluid Blue DEF having various application ::: The most importat use of DEF is for reduction of Nitrous Oxide ( NO ). DEF help full combustion of soot and to prevent them exhausting unburnt fuel.
■ It is used in NOx reduction and as a nutrient component in organic waste water treatment plants.
■ In the manufacture of liquid feed supplement for ruminant animals
■ In plywood and coreboard adhesives
■ Textile processing and coatings
■ In some paper coatings.
Urea is also consumed in animal feeds, other chemical manufacturing, as an alternative to rock salt for de-icing, as an effluent treatment plant or fermentation nutrient and is growing in diesel emissions control.
Diesel exhaust fluid (DEF) can be dosed directly into the exhaust pipeline, where the urea molecule rapidly vaporizes and dissociate into ammonia and carbon dioxide. This process prohibit the formation of Nitrous oxide ( NOx) And finally ammonia (NH3) chemically changes into water ( H2O) and nitrogen (N2), which is not harmfull; and these are then released through the exhaust.
