Technical Grade Urea

 

Technical Grade Urea/ Urea used for AdBlue

The issue of global warming is responsible for many environmental problems in the world, including incessant flooding, drought, and rising sea levels. All these environmental hazards are linked to the unprecedented spike in the amount of nitrogen oxides (NOx), which are dangerous, in the atmosphere, resulting in acid rain and impenetrable smog. Moreso, nitrogen oxides can affect the human respiratory systems and cause certain burning irritation in human eyes.

The seriousness of these environmental problems prompted some countries to urgently look for the most appropriate solution to minimize the impact of nitrogen oxides. One of the suitable approaches adopted by these countries  is the use of AdBlue. The primary raw material for producing AdBlue is urea. The AdBlue Urea, also referred to as SCR Urea or Technical Grade Urea, is an uncoated kind of urea, required for the manufacturing of AUS40, AdBlue, and Marine Urea.

Automotive Grade Urea must be used to produce AdBlue which is  in compliance with the ISO 22241 specification. More importantly, it is uncoated and free from aldehyde and heavy metals. As a matter of fact, most of the AdBlue/AUS32/ARLA32 solutions used in road vehicles, railway locomotives, power generators, off-road equipment, and agricultural machinery are manufactured using urea prills.

This is how SCR Urea/AdBlue works: It should be injected into a vehicle’s exhaust pipe. The urea in the AdBlue solution will be hydrolyzed into ammonia. The ammonia will then react with nitrogen oxides to produce nitrogen gas (N2) and water. Nitrogen gas is generally harmless, and it will vaporize. The water produced is then let out via the exhaust pipes.

As a white, crystalline organic substance that is safe and odourless, urea can also readily dissolve in water. Urea can be manufactured in the forms of granular and prills.

The Selective Catalytic Reduction (SCR) systems are inbuilt in vehicles. Urea, used in SCR systems, neutralises nitrogen oxides (NO and NO2), which are dangerous to people and the environment. The AdBlue/AUS32/ARLA32 solutions consist of 32.5% of urea, and AUS40 and Marine Urea contain 40% of urea. The engines of vehicles that utilise diesel need urea to stay clean and function properly.

SCR Urea makes it possible for vehicle owners to enjoy longer miles per gallon (MPG) because urea increases the efficiency of their vehicles’ engines, thereby reducing how much they spend on fuel.

As a distributor of high-grade urea, AirNox is capable of maintaining a continuous supply of urea to our customers. At AirNox, we can offer urea prill/granular in 1000kg big bags or in 25kg sacks.
