DHP AdBlue® AUS 32 (Aqueous Urea Solution 32.5 %) in IBC 1000L
DHP AdBlue® is NOx reducing agent AUS 32 for Selective Catalytic Reduction (SCR) systems
For diesel engines, direct diesel injection technology has developed to the point where it can
nearly be called the standard technology. The very tough legislation now in place to regulate diesel
engine exhaust emissions makes exhaust after treatment technology a must. That is why many of
today's passenger car diesel engines are equipped with oxidation catalytic converters. Further
exhaust after treatment systems will be needed for at least the heavier vehicles in the passenger
car and light commercial vehicle categories in order to comply with the latest emissions
regulations.
A range of different systems are currently in development, and in some cases already in use, for
reducing NOx emissions. In heavy commercial vehicles, NOx catalytic converters employing urea
as the reduction agent provide a system for the highly selective reduction of nitrogen oxide
emissions. There is selective catalytic NOx reduction in the presence of ammonia here.
The urea/water solution introduced into the exhaust train is first converted into ammonia via an
upstream reaction stage. In the subsequent catalytic reduction process, the ammonia breaks down
most of the NOx to nitrogen and water.
The urea-SCR process for exhaust after treatment is state of the art. A detailed description of the
quality of the reducing agent must form the basis for the universal, manufacturer-independent
introduction of this technology and is essential for ensuring the long-term operation of the exhaust
after treatment system. The reducing agent requirements have been published in standards DIN
70070 (requirements) and DIN V 70071 (test procedure).
Standardization on international level has been completed and can be found in the international
standard ISO 22241-1:2006-10-15
An urea/water solution must be used for diesel engine vehicles based on the requirements of ISO
22241 In Europe, the brand name "AdBlue®" is frequently used for this quality.
When using qualities not conforming to the specification, damages to the Bluetec system cannot
be ruled out.
