AdBlue - Urea Solution / SCR CAT

 

Q and A's

1. What is AdBlue?Adblue is a very pure grade of urea that has to meet the automotive DIN 70070 specification which is being converted to an ISO standard.

2. What is the shelf life of AdBlue?As long as the stipulated storage conditions are observed, AdBlue has a shelf life of 12 months. However, if you still have some AdBlue after 12 months you don't need to dispose of it - you can have it analysed to check is still conforms to the AdBlue specification.

3. What happens if I don't put AdBlue in my vehicle?There will be no change in performance of early vehicles although the vehicle will be operating illegally and enforcement authorities such as VOSA have said they'll treat non-compliance seriously. However, in time vehicle's will be fitted with OBD that will reduce the power of the vehicles if they are run without AdBlue.

4. Will AdBlue be subject to tax or duty?Apart from VAT, no. It is understood there are no plans to introduce any duty.

5. Where can I buy AdBlue?As well as Volvo dealers, AdBlue will become available on some forecourts and truckstops. Bulk and IBC solutions are also easily installed at transport home depots/ yards to compliment existing fuel installations.

6. In what form can I buy AdBlue?AdBlue can be bought in packages of 10 litre canisters and 1000 litre IBC's (Intermediate Bulk Container's) as well as in bulk supplied by road tanker.

7. It is hazardous or dangerous?AdBlue is safe therefore not explosive, flammable or toxic and is not subject to any hazardous products regulations such as ADR. Storage installations do need to be bunded however to protect water courses from potential AdBlue ingress due to perhaps a tank failure. AdBlue doesn't directly pollute but can promote the growth of algae which can in turn take away oxygen for other marine life.

8. Do existing vehicles (such as Euro III) need changing or modifying? No, it only affects new vehicles although in certain cases some buses may have retrofit systems. This is due to their age and certain local air quality initiatives.

9. Is AdBlue; blue?No, it is a clear liquid very similar in appearance to water.

10. What is Air1?Air1 is a unique concept developed by Yara to ensure you a secured supply of the high-quality AdBlue needed in your SCR system. Yara has formed a partnership with Europe's largest distributor, Brenntag, to ensure the supply of AdBlue through the Air1 concept all accross Europe.

11. How much AdBlue will I need?It is expected that the average AdBlue consumption will be about 5% by volume of diesel consumption for Euro IV and about 6% for Euro V.

Yara operates the largest adblue centres

Yara owns and operates one of the world's largest Adblue plants in Sluiskil, Netherlands, to market the Air1 brand across Europe.

Yara is currently one of the largest producers of Adblue in the world.

Its plant will have an annual capacity of 200,000 tonnes of Air1, one of the key ingredients in the urea solution used to reduce nitrogen oxide emissions from heavy-duty vehicles in Europe.

AdBlue Wiki Entry - Adblue decay and contamination

AdBlue is the registered trademark for AUS32 (Aqueous Urea Solution 32.5%) and is used in a process called selective catalytic reduction (SCR) to reduce emissions of oxides of nitrogen from the exhaust of diesel engined motor vehicles.
As the name AUS32 would suggest, it is a 32.5% solution of high-purity urea in demineralized water that is clear, non-toxic and is safe to handle. However, it can be corrosive for some metals, and must be stored and transported using the correct materials. The AdBlue trademark is currently held by the German Association of the Automobile Industry (VDA), who ensure quality standards are maintained in accordance with ISO 22241 specifications.^[1]
AdBlue is carried onboard SCR-equipped vehicles in specially designed tanks, and is dosed into the SCR system at a rate equivalent to 3–5% of diesel consumption. This low dosing rate ensures long refill periods and minimises the tank's impact on chassis space. On-highway SCR systems are currently in use throughout Europe, in Japan, Australia, Hong Kong, Taiwan, Korea, New Zealand and Singapore. The United States Environmental Protection Agency‎'s (US EPA) 2010 legislation will limit NOx to levels that will require North American trucks to be equipped with SCR post-2010. The current generic name in North America for AUS32 is diesel exhaust fluid (DEF). Some trucking industry OEMs have already developed branded SCR solutions, such as Daimler's BlueTec.
All European truck manufacturers currently offer SCR equipped models, and the future Euro6 emission standard is set to reinforce the demand for this technology. SCR systems are sensitive to potential chemical impurities in the urea solution, therefore, it is essential to maintain high standards of AdBlue quality according to the ISO 22241 standard.
The use of SCR technology in Europe made it necessary to develop an AdBlue supply infrastructure. AdBlue is available from thousands of service stations, this locator finder is updated monthly with new Retail sites selling AdBlue. It can also be purchased in canisters of 5 or 10 litres at service stations. Larger quantities of AdBlue can be delivered in, for example, 208 litres (46 imp gal; 55 US gal) drums, 1,000 litres (220 imp gal; 260 US gal) intermediate bulk container (IBCs), and bulk.

Truck operators caught out by tightening of emissions standards

Truck operators must take notice and act in good time to avoid being caught out by the forthcoming tightening of the emissions standards within the London Low Emissions Zone (LEZ); that’s the message coming from the manufacturers and exhaust system suppliers alike.
