AdBlue
Product characteristic: |
 |
| |
|
AdBlue (NH2)2CO + H2O is a water solution of urea. It is obtained from technically pure urea (free from contaminants) and demineralised water. The urea content in the solution is 32.5%.
AdBlue is non-toxic, odour-free, colourless, safe and environment friendly. High quality of the solution must be assured not only at the production stage, but also during its transport and storage. |

| Transportation: |
|
| |
| In order to avoid contamination of AdBlue and corrosion of the equipment, all tanks, containers (together with the pipes), valves and instruments used for the storage, transport or handling of AdBlue should be made from highly alloyed austenite steel as well as various plastics (ethylene plastics, polypropylene plastics, isobutylene plastics, fluoroethylene plastics, etc.). To avoid contamination and ensure optimum quality, Zakłady Azotowe Puławy supply AdBlue using its own means of transport. |

| Usage: |
|
| |
|
AdBlue finds application in new generation Diesel engines which use the SCR (Selective Catalytic Reduction) technology. The catalyst used in this technology imposes high requirements with respect to the content of metals (i.e. Na, K, Mg, Ca, Al, and in particular heavy metals) in a urea solution. AdBlue is used in the SCR systems in the motor industry in connection with the new EU legislation regulating exhaust gases emission standards for Diesel engines.
In line with the provisions of EU directives, new, more stringent emission standards (the so-called “Euro IV” emission standard) became effective on October 1st 2006. These standards will be further tightened from October 1st 2008 with the coming into force of the “Euro V” emission standard. The new standards require producers of freight trucks with load capacity of over 3.5 tonnes to manufacture vehicles which are capable of meeting the new emission standards. This is possible thanks to the SCR technology. The SCR technology converts the oxides of nitrogen (NOx) into elementary nitrogen and water. In line with the Euro V emission standard, the emission of noxious nitrogen oxides was reduced by 60% and of particulate matter by at least 80%.
New freight trucks are equipped with additional tanks for AdBlue. AdBlue is dosed under high pressure directly into the catalytic converter of exhaust fumes (the SCR technology). This leads to reduced emissions of noxious exhaust gases, which cause the greenhouse effect and acid rain. |

| Storing Conditions: |
|
| |
| AdBlue is not flammable, but its storage in a temperature of more than 30 oC may cause its hydrolytic cleavage with ammonia as one of the cleavage products. On the other hand, in a temperature below –11.5 oC AdBlue crystallizes, and for this reason all the tanks, dispensers and valves should be insulated or even heated if needed. |
