From urea to AdBlue«4you
GreenChem produces AdBlue of the highest quality that can be used in SCR exhaust systems. We blend urea with pure (demineralized) water on our own blending sites. After blending, AdBlue will arrive at your location in the desired storage solution.
AdBlue« is produced by mixing pure water and pure non-coated urea prills. The water has to be heated up to 40░-45░C before urea is dosed into the reactor/mixer-tank. Urea dissolves quite fast, and a batch of AdBlue is ready after approximately 30 minutes.
An AdBlue blending site, how does it look?
A blending site for AdBlue mainly consist of five installations:
- Reverse Osmoses Unit (R.O. Unit)
This unit is used to purify water. Unpurified water contains salts and minerals that can cause the forming of deposits in SCR systems. Reverse osmoses is a way of filtering solutions through a membrane that allows only small molecules to pass freely. This will result in the parting of pure water and possibly harmful ‘solute’.
- Water tank
This tank is used to store purified water.
- Urea dosing system
This system will gradually add urea prills to the mixing tank, ensuring clot free AdBlue.
- Mixing tank
This is where the urea and pure water are blended into AdBlue. The water is heated and mixed with urea prills. The Adblue is ready for use after about thirty minutes.
- AdBlue storage tanks
These tanks are used to store AdBlue before it is transported to our customers.

Getting AdBlue to you
After AdBlue is mixed, it is ready for IBC filling or bulk delivery.
