Automotive Grade Urea

Automotive grade urea is well known as AdBlue urea, SCR Urea, DEF Urea. It is used for Aqueous Urea Solutions production.

AdBlue/DEF/AUS 32/ ARLA 32, commonly known as automotive urea fluid, is a consumable that must be used in SCR technology and is mainly used for exhaust gas treatment of diesel engines. With the policy for energy conservation and emission reduction, most light trucks on the market are now equipped with urea tanks, but what is the difference between automotive grade urea and the most common agricultural grade urea?

Although automotive grade urea is also urea, it is very different from agricultural grade urea. Automotive grade urea has strict ratio requirements, basically composed of high-purity urea and deionized water, and the mass fraction should be strictly controlled at 31.8%–33.2%. One of the quality standards is the degree of control of impurities, and there are many impurities such as particulate impurities in agricultural urea. Adding agricultural urea fluid to the car will cause fatal damage to the SCR system, and it will cost a lot to replace an SCR system in trucks.

Automotive grade urea is the raw material to produce AdBlue (DEF / AUS 32), which is a kind of liquid for reducing nitrogen oxide pollution in diesel vehicle exhaust.
