2What is AdBlue and why is it needed AdBlue is a high-purity aqueous Urea solution containing a 32.5% solution of Urea in water. The quality of AdBlue is important and is defined in a DIN standard, DIN 70070New legislation regarding exhaust emission limits have been set by the European Union. These new emission limits come into force in (EURO 4) and in 2008 (EURO 5). The limits are set out in several European Union Directives, including 88/77/EEC, 1999/96/EC and 2001/27/EC.Selective Catalytic Reduction (SCR) and AdBlue has been selected by the European Vehicle Manufactures as the solution to reduce the emissions from Diesel engines.SCR systems will be used on diesel powered heavy-duty vehicles over 3.5 tons to reduce the nitrogen oxide emissions (NOx). AdBlue usage amounts to approximately 3-4% of the fuel consumption on EURO 4 vehicles. A typical heavy-duty vehicle will consume approximately 3 tons of AdBlue each year.
3How does SCR technology work SCR is an after-treatment system which deals with emissions in the exhaust system. AdBlue is mixed with air and injected directly into a catalytic converter inside the exhaust system. A chemical reaction takes place which converts the NOx present in the exhaust into a harmless gas and water.Dosing & control systemCompressed airAdBlue tankClean exhaustExhaust gases from the engineCatalytic convertersTypical SCR system on vehicle (Example from BOSCH)
4Projected Requirement for AdBlue in Europe The requirement for AdBlue will increase steadily over the coming years. It is estimated that by 2010 the yearly demand for AdBlue will exceed 4 million tons per year and around 20,000 filling locations will exist in Europe.
5Careful Handling is Required Although AdBlue is considered non-hazardous it presents several challenges when it comes to storing and handling the chemical on a daily basis. AdBlue has the following specific propertiesIt quickly crystallises when exposed to airIt freezes at -11oCIt has a corrosive effect on some common metalsIt should be protected for contaminationIt should not be released freely into the environmentThese properties require that AdBlue is handled with care. Any equipment that comes in contact with AdBlue must be made of suitable materials to prevent corrosion and contamination.Dispensing systems must minimise contact with air to prevent crystallisation, provide protection from cold weather and prevent spillage. Conventional dispensing equipment is not suitable for handling AdBlue.
6AdBlue Requires a Sealed Connection To ensure AdBlue can be handled in a reliable and safe way, IDENTIC has developed a sealed dispensing system for refilling AdBlue on vehicles. This spill-free vehicle refilling system provides the following advantagesIt prevents the risk of spillage reducing the risk of crystallisation and corrosion on the vehicle and at the filling pointIt ensures only AdBlue can be filled in the vehicles AdBlue tank preventing the risk of incorrect filling which could permanently damage the vehicles SCR equipment or create a hazardIt protects the quality of AdBlue preventing the risk of contamination, ensuring the vehicle reaches the emission standards it was designed to achieve.Unique interface not interchangeableConventionalDiesel NozzleSpill-free AdBlue nozzle
8AdBlue SVR Nozzle and Tank Inlet Adaptor IDENTIC has designed a spill-free nozzle specifically for use with AdBlue. The SVR Nozzle provides a sealed connection between the dispenser and the vehicles AdBlue tank.Key BenefitsOnly AdBlue can be filled in AdBlue tankNo spillageNo crystallisationProtects SCR-system from contaminationAutomatically filling to correct level
9AdBlue SVR Tank Inlet Adaptor A tank inlet adaptor is fitted inside the neck of the vehicles AdBlue tank. This allows the SVR Nozzle to be connected and ensures only AdBlue can be filled in the tank.Key BenefitsCan be installed by the vehicle manufacturer or tank supplierMay be retrofitted by the vehicle operatorAdaptable for all types of vehicle tanksAllows the tank inlet to be positioned at all anglesBuilt-in pressure and expansion control
10Designs for Tank Inlet Adaptors A range of tank inlet adaptors are being produced to suit different AdBlue tank designs
